0.9.0
|
|
||||||
-----
|
|
||||||
|
|
||||||
* [BC Break] Remove the `providerClass` argument of `#[CompletionProvider]`. Use `provider:`, which takes the same class-string and is now the first positional argument.
|
|
||||||
* Add `HttpTransport::getSessionId()` to read the server-minted `Mcp-Session-Id`: a request-scoped caller can persist it and pass it back through the constructor's `$headers` on a later transport. Always `null` on `2026-07-28`, which removed protocol-level sessions.
|
|
||||||
* Fix OIDC discovery rejecting issuers with a trailing slash (e.g. Authentik, Auth0).
|
|
||||||
|
|
||||||
0.8.0
|
|
||||||
-----
|
|
||||||
|
|
||||||
* Support for MCP spec version 2026-07-28 incl. stateless HTTP transport
|
|
||||||
* Negotiate the protocol revision during `initialize`: the server counter-offers a revision it supports and the client fails the handshake instead of continuing on an unagreed one. Adds `Client::getProtocolVersion()`.
|
|
||||||
* Serve both protocol eras from one endpoint: `StreamableHttpTransport` classifies each request (`InboundClassifier`) and routes it to the matching dispatcher, so one URL answers modern and handshake-era clients alike. `Builder::withoutModernEra()` opts out, `Builder::setModernVersions()` narrows the modern leg.
|
|
||||||
* Speak the lifecycle from the client: `Client` opens with `server/discover`, stamps `_meta` with version, capabilities and client info, and sends the `Mcp-Method`/`Mcp-Name`/`Mcp-Param-*` headers (via `Client\Stateless\ToolCatalog`). `Schema\Wire\McpHeader` holds the shared header names.
|
|
||||||
* Add multi round-trip requests (SEP-2322): a handler returning `InputRequiredResult` yields `resultType: "input_required"` with an opaque, signed `requestState` (`RequestStateCodec`, key via `Builder::setRequestState()`); the client retries with `inputResponses`, read through `RequestContext::getInputContext()` and its typed `elicitResult()`/`samplingResult()`/`rootsResult()`. On the client, `InputRequestResolver` answers such results automatically from the host's elicitation, sampling and roots handlers.
|
|
||||||
* Serve `ClientGateway::elicit()`/`elicitUrl()` on every revision: where the client cannot be asked mid-request, `Server\Stateless\ElicitationReplay` turns the ask into `input_required` and resumes once re-sent — the handler is entered once per ask. `InputRequiredShim` does the reverse for handshake-era clients. `sample()`/`listRoots()` raise a `LogicException` on `2026-07-28`, which removed them.
|
|
||||||
* Run stateless handlers in a fiber so `$gateway->progress()`/`log()` stream over SSE when the handler emits something and the client accepts `text/event-stream`; honour `io.modelcontextprotocol/logLevel` (SEP-2575). Adds `LoggingLevel::severity()`/`isAtLeast()`.
|
|
||||||
* Deliver notifications on `subscriptions/listen` (SEP-2575) via `NotificationBusInterface` — `InMemoryNotificationBus` for persistent runtimes, `Psr16NotificationBus` for PHP-FPM — set with `Builder::setNotificationBus()`; `Builder::setSubscriptionLifetime()` replaces the hard-coded 30s ceiling.
|
|
||||||
* Validate the standard request headers (SEP-2243) with `StandardHeaderValidator` (`Builder::setHeaderValidator()`), answering `-32020` when they contradict the body.
|
|
||||||
* Add `Wire\CachePolicy` (`Builder::setCachePolicy()`) for SEP-2549 caching hints; defaults to `ttlMs: 0, cacheScope: private`. A `ReadResourceResult` may override with its own values.
|
|
||||||
* Carry W3C trace context (SEP-414): `traceparent`/`tracestate`/`baggage` from `_meta` are exposed via `RequestContext::getTraceContext()` and echoed onto the request's notifications.
|
|
||||||
* Close the schema gaps for `2025-06-18`/`2025-11-25` and add the `2026-07-28` surface (SEP-2106): url-mode elicitation (`ClientGateway::elicitUrl()`/`supportsElicitationUrl()`), `Implementation::title`, and `outputSchema`/`structuredContent` accepting any JSON value.
|
|
||||||
* Deprecate Roots, Sampling and Logging (SEP-2577, earliest removal `2027-07-28`); they keep working but trigger a deprecation notice.
|
|
||||||
* [BC Break] Answer a not-found subject with `-32602` instead of `-32002` (SEP-2164): `resources/read` picks the code by revision (`-32602` from `2026-07-28` on), `prompts/get`, `completion/complete` and `tools/call` switch on every revision. Adds `ProtocolVersion::usesInvalidParamsForResourceNotFound()`.
|
|
||||||
* [BC Break] A list-shaped tool result is only sent as `structuredContent` on `2026-07-28`+; older revisions keep the JSON-encoded value in `content`.
|
|
||||||
* [BC Break] Add the extensions framework (SEP-2133) MCP Apps sits on: `ExtensionInterface::getId()` returns an `ExtensionIdentifier` value object, and the interface gains `getMessages()`/`getRequestHandlers()` (extend `AbstractExtension` to skip both). `MessageFactory::make()` takes an `$additional` message list; `RequestHandlerInterface`'s result template is covariant. `ServerExtensionInterface` is replaced by the side-agnostic `Schema\Extension\ExtensionInterface`.
|
|
||||||
* Add client-side extension negotiation: `ClientGateway::supportsExtension()`, `Client\Builder::enableExtension()`, `ClientCapabilities::withExtensions()`.
|
|
||||||
* Add sampling-with-tools: sampling requests can carry tools and tool-choice preferences, messages support tool-use/tool-result blocks, and clients advertise `sampling.context`/`sampling.tools` (`ClientGateway::supportsSamplingTools()`/`supportsSamplingContext()`). Requests violating the tool-flow rules are rejected with a JSON-RPC error.
|
|
||||||
* [BC Break] `SamplingMessage::$content` and `CreateSamplingMessageResult::$content` may be a list of content blocks — use `getContentBlocks()`. `CreateSamplingMessageResult` rejects roles other than `assistant` and empty content.
|
|
||||||
* Add client-side Roots support (`RootsCallbackInterface`, `Client::sendRootsListChanged()`) and server-side `ClientGateway::listRoots()`/`supportsRoots()`/`supportsSampling()`.
|
|
||||||
* Add `Schema\Content\ResourceLink` to reference a resource by URI in tool results and prompt messages.
|
|
||||||
* [BC Break] `Schema\JsonRpc\Error` accepts `null` as `$id`; an unreadable id now omits the member instead of sending `"id": ""`. `MessageFactory` decodes a missing or null id as an id-less error.
|
|
||||||
* Preserve the request `id` on an invalid-but-parseable message (`-32600`) via `InvalidInputMessageException::getRequestId()`.
|
|
||||||
* [BC Break] Drop the SDK-only name pattern on `ResourceDefinition`/`ResourceTemplate` `$name`; the spec allows any string.
|
|
||||||
* Log expected tool failures (`ToolCallException`) at debug level instead of error.
|
|
||||||
* Add `annotations` to `ImageContent`.
|
|
||||||
* Fix empty tool/resource schemas serializing as `[]` instead of `{}`.
|
|
||||||
* Fix `PromptResultFormatter` dropping `annotations`, `_meta` and `mimeType` for plain-array content.
|
|
||||||
|
|
||||||
0.7.0
|
|
||||||
-----
|
|
||||||
|
|
||||||
* Add client-side elicitation support: `ElicitationCallbackInterface`, `ElicitationRequestHandler`, and `ElicitationException` let clients respond to server elicitation requests.
|
|
||||||
* Defer element loading to the first registry read: loaders now run at request time (first `has*`/`get*` call) instead of eagerly at `Builder::build()`, fixing empty registries under persistent runtimes (e.g. FrankenPHP worker mode) where a loader's data source is not ready at build time. Adds `Builder::setLazyLoading()` (default on), a public `Registry::load()`, and an optional `LoaderInterface` constructor argument on `Registry`.
|
|
||||||
* [BC Break] Element loading is lazy by default: loader failures now surface on the first request rather than at `Builder::build()`, and `initialize` advertises capabilities from the configured sources rather than the loaded registry. Call `Builder::setLazyLoading(false)` to restore eager build-time loading.
|
|
||||||
* Allow `[$instance, 'methodName']` as an element handler in `Builder::addTool()`, `addResource()`, `addResourceTemplate()`, and `addPrompt()`. Unblocks handlers with constructor dependencies that the container-less `new $className()` fallback cannot build.
|
|
||||||
* Always emit an `items` schema for array tool parameters: untyped arrays get `items: {}` and nullable typed arrays (e.g. `string[]|null`) keep their element type. Fixes strict clients rejecting tools with "array type must have items" (#151).
|
|
||||||
* Harden JSON-RPC input parsing: single-message vs batch is now decided from the decoded JSON type (object → single, list array → batch) instead of the raw first byte. Scalars, empty payloads, and non-object batch elements are surfaced as `InvalidInputMessageException` entries instead of triggering warnings or a `TypeError`.
|
|
||||||
* Add `maxBatchSize` (default `100`) to `MessageFactory` — oversized JSON-RPC batches are rejected before any message is constructed, guarding against amplification.
|
|
||||||
* Add `maxBodyBytes` (default 4 MiB) to `StreamableHttpTransport` — POST bodies exceeding the cap are rejected with `413`. Unknown-size/chunked bodies are read incrementally and stopped at the cap so they cannot exhaust memory.
|
|
||||||
* Reject malformed `Mcp-Session-Id` headers with a `400` response: a repeated header or a value that is not a valid UUID is now rejected up front instead of surfacing as an uncaught `Uuid::fromString()` error.
|
|
||||||
* Extract RFC 9728 metadata serving into `ProtectedResourceMetadataHandler`, a transport-neutral PSR-15 `RequestHandlerInterface` that can be mounted directly as a Symfony/Laravel controller; `ProtectedResourceMetadataMiddleware` now delegates to it (no BC break).
|
|
||||||
|
|
||||||
0.6.0
|
|
||||||
-----
|
|
||||||
|
|
||||||
* Add `Builder::add(Tool|ResourceDefinition|ResourceTemplate|Prompt $definition, ElementHandlerInterface $handler)` for explicit registration of elements whose schema is only known at runtime.
|
|
||||||
* Add handler interfaces `ToolHandlerInterface`, `ResourceHandlerInterface`, `ResourceTemplateHandlerInterface`, `PromptHandlerInterface`, and the `ElementHandlerInterface` marker.
|
|
||||||
* [BC Break] Renamed `Mcp\Schema\Resource` to `Mcp\Schema\ResourceDefinition`. No alias.
|
|
||||||
* [BC Break] Renamed `Mcp\Capability\Registry\Loader\ArrayLoader` to `Mcp\Capability\Registry\Loader\ReflectedElementLoader`.
|
|
||||||
* [BC Break] Bump default protocol version to `2025-11-25`
|
|
||||||
* Add support for MCP Apps extension in schema and server
|
|
||||||
* Add `extensions` to `ServerCapabilities` and `ClientCapabilities` and `Builder::enableExtension()`
|
|
||||||
* Allow overriding the default name pattern for Discovery
|
|
||||||
* Add configurable session garbage collection (`gcProbability`/`gcDivisor`)
|
|
||||||
* Add optional `title` field to `ResourceDefinition` and `ResourceTemplate` for MCP spec compliance
|
|
||||||
* Add `ChainLoader` to compose multiple `LoaderInterface` implementations via explicit ordering.
|
|
||||||
* Add `RegistryInterface::unregisterTool()`, `unregisterResource()`, `unregisterResourceTemplate()`, `unregisterPrompt()` — idempotent removals.
|
|
||||||
* Add `RegistryInterface::hasTool()`, `hasResource()`, `hasResourceTemplate()`, `hasPrompt()` — by-name existence checks.
|
|
||||||
* `DiscoveryLoader` now refreshes only its own previously written entries; manual registrations (via `Builder::addTool()` etc. or runtime `$registry->registerTool()` calls) survive rediscovery, and a same-name manual registration takes precedence over discovery on collision.
|
|
||||||
* [BC Break] Removed `ElementReference::$isManual` public property and the `bool $isManual` parameter from all `*Reference` constructors. Origin tracking is no longer carried on the element; manual-over-discovered precedence is encoded by loader execution order.
|
|
||||||
* [BC Break] `RegistryInterface::registerTool()`, `registerResource()`, `registerResourceTemplate()`, `registerPrompt()` lost their trailing `bool $isManual = false` parameter. Callers using positional arguments must drop the flag.
|
|
||||||
* [BC Break] Removed `RegistryInterface::clear()`, `getDiscoveryState()`, `setDiscoveryState()`. Rediscovery now goes through `DiscoveryLoader::load()` directly.
|
|
||||||
* `Registry::register*()` semantics changed to plain last-write-wins (overwrites silently) and the methods now return the stored `*Reference`. The previous "discovered registration is ignored when a manual one already exists" precedence rule still applies, but is now enforced by `DiscoveryLoader` via reference-identity tracking — and still emits a debug log when a discovery is skipped due to a conflicting registration.
|
|
||||||
* Add optional `title` parameter to `Builder::addResource()` and `Builder::addResourceTemplate()` for MCP spec compliance
|
|
||||||
* [BC Break] `Builder::addResource()` signature changed — `$title` parameter added between `$name` and `$description`. Callers using positional arguments must switch to named arguments.
|
|
||||||
* [BC Break] `Builder::addResourceTemplate()` signature changed — `$title` parameter added between `$name` and `$description`. Callers using positional arguments must switch to named arguments.
|
|
||||||
* Add `CorsMiddleware`, `DnsRebindingProtectionMiddleware`, and `ProtocolVersionMiddleware` for `StreamableHttpTransport`, composed automatically as the default stack via `StreamableHttpTransport::defaultMiddleware()`
|
|
||||||
* [BC BREAK] `StreamableHttpTransport` constructor: `$corsHeaders` parameter removed; CORS is now configured via `CorsMiddleware`. The `$middleware` parameter is nullable — `null` (or omitted) installs the default stack; `[]` disables all defaults. Default `Access-Control-Allow-Origin` is no longer set (was `*`).
|
|
||||||
* [BC Break] `ResourceDefinition::__construct()` signature changed — `$title` parameter added between `$name` and `$description`. Callers using positional arguments must switch to named arguments.
|
|
||||||
* [BC Break] `ResourceTemplate::__construct()` signature changed — `$title` parameter added between `$name` and `$description`. Callers using positional arguments must switch to named arguments.
|
|
||||||
* [BC Break] `McpResource` and `McpResourceTemplate` attribute signatures changed — `$title` parameter added between `$name` and `$description`. Callers using positional arguments must switch to named arguments.

# Contributing
|
|
||||||
|
|
||||||
Thanks for considering a contribution to the PHP SDK for the Model Context Protocol. This is a
|
|
||||||
collaboration between [the PHP Foundation](https://thephp.foundation/) and the
|
|
||||||
[Symfony project](https://symfony.com/), and it follows Symfony's conventions throughout.
|
|
||||||
|
|
||||||
## Ways to contribute
|
|
||||||
|
|
||||||
- **Report a bug** or **propose a feature** by [opening an issue](https://github.com/modelcontextprotocol/php-sdk/issues).
|
|
||||||
Check existing issues first — many spec-driven changes are already tracked under the relevant
|
|
||||||
`2026-07-28`-style release label.
|
|
||||||
- **Send a pull request** for a fix, a new capability, or a docs improvement.
|
|
||||||
- **Improve the guides** under `docs/` — see [Documentation](#documentation) below for how they're built.
|
|
||||||
- **Help close a conformance gap** — `make conformance-tests` runs the official MCP conformance
|
|
||||||
suite against this SDK; a failing scenario there is a concrete, well-scoped contribution.
|
|
||||||
|
|
||||||
## Development setup
|
|
||||||
|
|
||||||
Requires PHP 8.1+.
|
|
||||||
|
|
||||||
```bash
|
|
||||||
composer install
|
|
||||||
```
|
|
||||||
|
|
||||||
## Before opening a pull request
|
|
||||||
|
|
||||||
Run the full CI suite locally:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
make ci
|
|
||||||
```
|
|
||||||
|
|
||||||
This runs, in order: `make cs` (PHP CS Fixer, auto-fixes style), `make phpstan` (static analysis),
|
|
||||||
and `make tests` (unit + inspector tests). All three must pass. If your change touches
|
|
||||||
protocol-observable behavior, also run:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
make conformance-tests # requires Docker
|
|
||||||
```
|
|
||||||
|
|
||||||
## Coding standards
|
|
||||||
|
|
||||||
This project follows [Symfony's coding standards](https://symfony.com/doc/current/contributing/code/standards.html)
|
|
||||||
and [backward compatibility promise](https://symfony.com/doc/current/contributing/code/bc.html). In short:
|
|
||||||
|
|
||||||
See [CLAUDE.md](CLAUDE.md) for a fuller tour of the codebase's architecture and layout.
|
|
||||||
|
|
||||||
## Tests
|
|
||||||
|
|
||||||
New capabilities need unit tests (`tests/Unit/`) covering the core logic, and — for anything
|
|
||||||
reachable over the wire — inspector tests (`tests/Inspector/`) for end-to-end coverage. If you're
|
|
||||||
adding a documented pattern, consider adding or updating an example under `examples/`.
|
|
||||||
|
|
||||||
## Documentation
|
|
||||||
|
|
||||||
The guides under `docs/` are built with [Zensical](https://zensical.org/) in `--strict` mode,
|
|
||||||
which fails the build on a broken internal link:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
make docs-guides
|
|
||||||
```
|
|
||||||
|
|
||||||
Links between guide pages must be relative paths that resolve within `docs/` (e.g.
|
|
||||||
`protocol-versions.md`, `../CLAUDE.md` will *not* resolve — Zensical only follows the `docs/` tree).
|
|
||||||
For anything at the repo root (`CLAUDE.md`, `ROADMAP.md`, `CHANGELOG.md`), link to it by its GitHub
|
|
||||||
URL instead, matching the pattern already used across `docs/`. The class-level API reference is
|
|
||||||
generated separately by phpDocumentor (`make docs-api`) and isn't hand-written.
|
|
||||||
|
|
||||||
## Versioning
|
|
||||||
|
|
||||||
The SDK follows [Semantic Versioning](https://semver.org/) — see
|
|
||||||
[SDK tier target](docs/sdk-tier.md#versioning) for what that means pre- and post-1.0, and how it
|
|
||||||
lines up with Symfony's backward compatibility promise.
|
|
||||||

||||||

||||||
If something is unclear or you want early feedback on an approach before writing code, open an
|
|
||||||
issue or a draft pull request — that's the right place to ask, rather than guessing at scope.

## Build a server
|
## Overview
|
||||||
|
|
||||||
A server is a plain PHP class plus three lines of wiring:
|
The MCP PHP SDK provides both **server** and **client** implementations for the Model Context Protocol, enabling you to:
|
||||||
|
|
||||||
|
- **Build MCP Servers**: Expose your PHP application's functionality (tools, resources, prompts) to AI agents
|
||||||
|
- **Build MCP Clients**: Connect to and interact with MCP servers from your PHP applications
|
||||||
|
|
||||||
|
## Server SDK
|
||||||
|
|
||||||
|
Build MCP servers to expose your PHP application's capabilities to AI agents like Claude, Codex, and others.
|
||||||
|
|
||||||
|

### Server Capabilities
|
||||||
[Try it with the Inspector](docs/get-started/inspector.md) shows it running.
|
|
||||||
|
|
||||||
## Build a client
|
- **Tools**: Executable functions that AI agents can call
|
||||||
|
- **Resources**: Data sources that can be read (files, configs, databases)
|
||||||
|
- **Resource Templates**: Dynamic resources with URI parameters
|
||||||
|
- **Prompts**: Pre-defined templates for AI interactions
|
||||||
|
- **Server-Initiated Communication**: Elicitations, sampling, logging, progress notifications
|
||||||
|
|
||||||
|
### Registration Methods
|
||||||
|
|
||||||
|
There are multiple ways to register your MCP capabilities—choose the approach that best fits your application's architecture:
|
||||||
|
|
||||||
|
**1. Attribute-Based Discovery** — Define capabilities using PHP attributes for automatic discovery:
|
||||||
|
```php
|
||||||
|
#[McpTool]
|
||||||
|
public function generateReport(): string { /* ... */ }
|
||||||
|
|
||||||
|
#[McpResource(uri: 'config://app/settings')]
|
||||||
|
public function getConfig(): array { /* ... */ }
|
||||||
|
```
|
||||||
|
|
||||||
|
**2. Manual Registration** — Register capabilities programmatically without attributes:
|
||||||
|
```php
|
||||||
|
$server = Server::builder()
|
||||||
|
->addTool([Calculator::class, 'add'], 'add_numbers')
|
||||||
|
->addResource([Config::class, 'get'], 'config://app')
|
||||||
|
->build();
|
||||||
|
```
|
||||||
|
|
||||||
|
**3. Hybrid Approach** — Combine both methods for maximum flexibility:
|
||||||
|
```php
|
||||||
|
$server = Server::builder()
|
||||||
|
->setDiscovery(__DIR__, ['.'])
|
||||||
|
->addTool([ExternalService::class, 'process'], 'external')
|
||||||
|
->build();
|
||||||
|
```
|
||||||
|
|
||||||
|
### Transports
|
||||||
|
|
||||||
|
Choose the transport that matches your deployment environment:
|
||||||
|
|
||||||
|
**1. STDIO Transport** — For command-line integration and local processes:
|
||||||
|
```php
|
||||||
|
$transport = new StdioTransport();
|
||||||
|
$server->run($transport);
|
||||||
|
```
|
||||||
|
|
||||||
|
**2. HTTP Transport** — For web-based servers and distributed systems:
|
||||||
|
```php
|
||||||
|
$transport = new StreamableHttpTransport($request, $responseFactory, $streamFactory);
|
||||||
|
$response = $server->run($transport);
|
||||||
|
```
|
||||||
|
|
||||||
|
### Session Management
|
||||||
|
|
||||||
|
Configure session storage to maintain state between requests. Choose the backend that fits your infrastructure:
|
||||||
|
|
||||||
|
**In-Memory** (default, suitable for STDIO):
|
||||||
|
```php
|
||||||
|
$server = Server::builder()
|
||||||
|
->setSession(ttl: 7200) // 2 hours
|
||||||
|
->build();
|
||||||
|
```
|
||||||
|
|
||||||
|
**File-Based** (suitable for single-server HTTP deployments):
|
||||||
|
```php
|
||||||
|
$server = Server::builder()
|
||||||
|
->setSession(new FileSessionStore(__DIR__ . '/sessions'))
|
||||||
|
->build();
|
||||||
|
```
|
||||||
|
|
||||||
|
**PSR-16 Cache** (for example with Redis for scaled deployments):
|
||||||
|
```php
|
||||||
|
$server = Server::builder()
|
||||||
|
->setSession(new Psr16SessionStore(
|
||||||
|
cache: new Psr16Cache($redisAdapter),
|
||||||
|
prefix: 'mcp-',
|
||||||
|
ttl: 3600
|
||||||
|
))
|
||||||
|
->build();
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Client SDK
|
||||||
|
|
||||||
|
Connect to MCP servers from your PHP applications to access their tools, resources, and prompts.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
```php
|
```php
|
||||||
use Mcp\Client;
|
use Mcp\Client;
|
||||||
use Mcp\Client\Transport\StdioTransport;
|
use Mcp\Client\Transport\StdioTransport;
|
||||||
|
|
||||||
|
// Build the client
|
||||||
$client = Client::builder()
|
$client = Client::builder()
|
||||||
->setClientInfo('My Application', '1.0.0')
|
->setClientInfo('My Application', '1.0.0')
|
||||||
|
->setInitTimeout(30)
|
||||||
|
->setRequestTimeout(120)
|
||||||
->build();
|
->build();
|
||||||
|
|
||||||
$client->connect(new StdioTransport(command: 'php', args: ['/path/to/server.php']));
|
// Connect to a server
|
||||||
|
$transport = new StdioTransport(
|
||||||
|
command: 'php',
|
||||||
|
args: ['/path/to/server.php'],
|
||||||
|
);
|
||||||
|
|
||||||
|
$client->connect($transport);
|
||||||
|
|
||||||
|
// Discover and use capabilities
|
||||||
$tools = $client->listTools();
|
$tools = $client->listTools();
|
||||||
$result = $client->callTool('add', ['a' => 5, 'b' => 3]);
|
$result = $client->callTool('add', ['a' => 5, 'b' => 3]);
|
||||||
|
|
||||||
|
$resources = $client->listResources();
|
||||||
|
$content = $client->readResource('config://calculator/settings');
|
||||||
|
|
||||||
$client->disconnect();
|
$client->disconnect();
|
||||||
```
|
```

||||||
|

|
```php
|
||||||
|
$result = $client->callTool(
|
||||||
|
name: 'process_data',
|
||||||
|
arguments: ['dataset' => 'large_file.csv'],
|
||||||
|
onProgress: function (float $progress, ?float $total, ?string $message) {
|
||||||
|
echo "Progress: {$progress}/{$total} - {$message}\n";
|
||||||
|
}
|
||||||
|
);
|
||||||
|
```
|
||||||
|
|
||||||
|
- **Sampling Support**: Handle server LLM sampling requests
|
||||||
|
```php
|
||||||
|
$samplingHandler = new SamplingRequestHandler($myCallback);
|
||||||
|
$client = Client::builder()
|
||||||
|
->setCapabilities(new ClientCapabilities(sampling: true))
|
||||||
|
->addRequestHandler($samplingHandler)
|
||||||
|
->build();
|
||||||
|
```
|
||||||
|
|
||||||
|
- **Logging Notifications**: Receive server log messages
|
||||||
|
```php
|
||||||
|
$loggingHandler = new LoggingNotificationHandler($myCallback);
|
||||||
|
$client = Client::builder()
|
||||||
|
->addNotificationHandler($loggingHandler)
|
||||||
|
->build();
|
||||||
|
```
|
||||||
|
|
||||||
|
### Transports
|
||||||
|
|
||||||
|
Connect to MCP servers using the transport that matches your setup:
|
||||||
|
|
||||||
|
**1. STDIO Transport** — Connect to local server processes:
|
||||||
|
```php
|
||||||
|
$transport = new StdioTransport(
|
||||||
|
command: 'php',
|
||||||
|
args: ['/path/to/server.php'],
|
||||||
|
);
|
||||||
|
|
||||||
|
$client->connect($transport);
|
||||||
|
```
|
||||||
|
|
||||||
|
**2. HTTP Transport** — Connect to remote or web-based servers:
|
||||||
|
```php
|
||||||
|
$transport = new HttpTransport('http://localhost:8000');
|
||||||
|
|
||||||
|
$client->connect($transport);
|
||||||
|
```

# 0001 — The MCP server is an OAuth Resource Server, not an Authorization Server
|
|
||||||
|
|
||||||
- Status: Accepted
|
|
||||||
- Date: 2026-06-15
|
|
||||||
|
|
||||||
## Context
|
|
||||||
|
|
||||||
OAuth 2.1 defines three distinct roles:
|
|
||||||
|
|
||||||
| Role | What it does | Status in this SDK | Scope |
|
|
||||||
|------|--------------|--------------------|-------|
|
|
||||||
| Resource Server | Validates incoming bearer tokens, serves Protected Resource Metadata (RFC 9728), emits `WWW-Authenticate` | Shipped (`AuthorizationMiddleware`, `JwtTokenValidator`, `ProtectedResourceMetadata`) | **IN scope** |
|
|
||||||
| Delegation / proxy to an upstream AS | Forwards `/authorize` and `/token` to your existing IdP | Shipped (`OAuthProxyMiddleware`) | **IN scope — delegation ONLY** |
|
|
||||||
| Authorization Server / Identity Provider (IdP) | Mints its own tokens, registers clients, runs login and consent | Absent | **OUT of scope** |
|
|
||||||
|
|
||||||
The SDK repeatedly receives pull requests that move it toward becoming a full OAuth 2.1
|
|
||||||
**authorization server** — asking the MCP server to mint its own access and refresh tokens,
|
|
||||||
register clients, and run login and consent flows, that is, to become an Identity Provider.
|
|
||||||
The most explicit example is [#373](https://github.com/modelcontextprotocol/php-sdk/pull/373)
|
|
||||||
("[Server] Add native OAuth 2.1 authorization server", ~3,400 lines across 50+ files), but the
|
|
||||||
direction has crept in incrementally rather than in one PR.
|
|
||||||
|
|
||||||
A contributing factor is that the SDK already exposes the *authorization-server endpoints in
|
|
||||||
proxy form*, and that surface has grown:
|
|
||||||
[#221](https://github.com/modelcontextprotocol/php-sdk/pull/221) added the OAuth resource-server
|
|
||||||
middleware, and [#269](https://github.com/modelcontextprotocol/php-sdk/pull/269) added Dynamic
|
|
||||||
Client Registration (RFC 7591). Today `OAuthProxyMiddleware` answers `/authorize`, `/token`, and
|
|
||||||
`/.well-known/oauth-authorization-server`, and DCR endpoints exist. The shape of that surface
|
|
||||||
invites contributors to "finish the job" by backing those endpoints with a real token issuer.
|
|
||||||
It is not scaffolding to be completed — it is a delegating proxy, and that is the whole of its
|
|
||||||
intent.
|
|
||||||
|
|
||||||
## Decision
|
|
||||||
|
|
||||||
**The MCP server is an OAuth 2.1 Resource Server that MAY delegate to an upstream
|
|
||||||
authorization server. It will NOT issue tokens or act as an Identity Provider.**
|
|
||||||
|
|
||||||
Concretely:
|
|
||||||
|
|
||||||
- The SDK validates bearer tokens, serves RFC 9728 Protected Resource Metadata, and emits
|
|
||||||
`WWW-Authenticate` challenges. This is the Resource Server role and is fully supported.
|
|
||||||
- The SDK MAY delegate `/authorize` and `/token` to an upstream authorization server via
|
|
||||||
`OAuthProxyMiddleware`. This is delegation only: the middleware redirects the browser to
|
|
||||||
the upstream `/authorize` endpoint and proxies `/token` requests to the upstream token
|
|
||||||
endpoint. It never mints, signs, stores, or rotates tokens of its own.
|
|
||||||
- The SDK will NOT implement an authorization server: no token issuance, no token signing or
|
|
||||||
key management, no login UI, no consent UI, no authorization-code or refresh-token storage,
|
|
||||||
no first-party Dynamic Client Registration acting as an issuer.
|
|
||||||
|
|
||||||
Pull requests that add authorization-server / IdP behavior are declined by reference to this
|
|
||||||
ADR.
|
|
||||||
|
|
||||||
## Rationale
|
|
||||||
|
|
||||||
- **Security liability.** Issuing tokens means owning signing-key generation, storage, and
|
|
||||||
rotation; authorization-code and refresh-token persistence; refresh-token rotation and
|
|
||||||
replay detection; and consent. A defect in any of these is a credential-issuance
|
|
||||||
vulnerability affecting every consumer of the SDK. This is precisely the surface an MCP SDK
|
|
||||||
should not own.
|
|
||||||
- **RFC footprint.** A correct authorization server must implement and keep current with
|
|
||||||
RFC 6749 (OAuth 2.0), RFC 7591 (Dynamic Client Registration), RFC 8414 (Authorization
|
|
||||||
Server Metadata), PKCE (RFC 7636), and refresh-token rotation guidance, among others. That
|
|
||||||
is an open-ended maintenance and conformance burden far outside the SDK's purpose.
|
|
||||||
- **Mature implementations already exist.** Token issuance is a solved problem.
|
|
||||||
`league/oauth2-server` provides it as a PHP library, and every production IdP — Keycloak,
|
|
||||||
Auth0, Microsoft Entra ID, Okta — provides it as a service. Re-implementing it inside an
|
|
||||||
MCP SDK adds risk without adding value.
|
|
||||||
|
|
||||||
## Boundary statement
|
|
||||||
|
|
||||||
`OAuthProxyMiddleware` **delegates** to an upstream IdP. It is **not** authorization-server
|
|
||||||
scaffolding to be completed. Backing its `/authorize` and `/token` endpoints with a
|
|
||||||
first-party token issuer is out of scope and will be declined.
|
|
||||||
|
|
||||||
## Consequences
|
|
||||||
|
|
||||||
- The supported authorization architecture is: an external authorization server (your IdP or
|
|
||||||
`league/oauth2-server` running in your own application) issues tokens; the MCP server
|
|
||||||
validates them as a Resource Server and optionally proxies the OAuth flow to that upstream.
|
|
||||||
- Contributors get a single, citable ruling for why authorization-server PRs are declined,
|
|
||||||
reducing repeated large-PR churn.
|
|
||||||
- Resource Server and proxy/delegation features remain welcome and supported.
|
|
||||||
|
|
||||||
## Alternatives / what to do instead
|
|
||||||
|
|
||||||
If you need an authorization server (token issuance, client registration, login, consent), do
|
|
||||||
**not** add it to this SDK. Instead:
|
|
||||||
|
|
||||||
- **Front the MCP server with an existing IdP** — Keycloak, Auth0, Microsoft Entra ID, or
|
|
||||||
Okta. Point `JwtTokenValidator` and `ProtectedResourceMetadata` at that issuer, and
|
|
||||||
optionally use `OAuthProxyMiddleware` to delegate `/authorize` and `/token` to it.
|
|
||||||
- **Run `league/oauth2-server` in your own application**, behind the SDK's existing proxy and
|
|
||||||
validator seams. The MCP server validates the tokens it issues; it does not issue them
|
|
||||||
itself.
|
|
||||||
|
|
||||||
See [`../docs/run/authorization.md`](../docs/run/authorization.md) for the supported Resource Server
|
|
||||||
and delegation setup.

# Custom Message Handlers
|
|
||||||
|
|
||||||
**Low-level escape hatch.** Custom message handlers run before the SDK's built-in handlers and give you total control over
|
|
||||||
individual JSON-RPC messages. They do not receive the builder's registry, container, or discovery output unless you pass
|
|
||||||
those dependencies in yourself.
|
|
||||||
|
|
||||||
> **Warning**: Custom message handlers bypass discovery, manual capability registration, and container lookups (unless
|
|
||||||
> you explicitly pass them). Tools, resources, and prompts you register elsewhere will not show up unless your handler
|
|
||||||
> loads and executes them manually. Reach for this API only when you need that level of control and are comfortable
|
|
||||||
> taking on the additional plumbing.
|
|
||||||
|
|
||||||
## Request Handlers
|
|
||||||
|
|
||||||
Handle JSON-RPC requests (messages with an `id` that expect a response). Request handlers **must** return either a
|
|
||||||
`Response` or an `Error` object.
|
|
||||||
|
|
||||||
Attach request handlers with `addRequestHandler()` (single) or `addRequestHandlers()` (multiple). You can call these
|
|
||||||
methods as many times as needed; handlers are collected in call order, and the whole custom list runs before the
|
|
||||||
built-in defaults:
|
|
||||||
|
|
||||||
```php
|
|
||||||
$server = Server::builder()
|
|
||||||
->addRequestHandler(new CustomListToolsHandler())
|
|
||||||
->addRequestHandlers([
|
|
||||||
new CustomCallToolHandler(),
|
|
||||||
new CustomGetPromptHandler(),
|
|
||||||
])
|
|
||||||
->build();
|
|
||||||
```
|
|
||||||
|
|
||||||
Request handlers implement `RequestHandlerInterface`:
|
|
||||||
|
|
||||||
```php
|
|
||||||
use Mcp\Schema\JsonRpc\Error;
|
|
||||||
use Mcp\Schema\JsonRpc\Request;
|
|
||||||
use Mcp\Schema\JsonRpc\Response;
|
|
||||||
use Mcp\Server\Handler\Request\RequestHandlerInterface;
|
|
||||||
use Mcp\Server\Session\SessionInterface;
|
|
||||||
|
|
||||||
interface RequestHandlerInterface
|
|
||||||
{
|
|
||||||
public function supports(Request $request): bool;
|
|
||||||
|
|
||||||
public function handle(Request $request, SessionInterface $session): Response|Error;
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
- `supports()` decides if the handler should process the incoming request
|
|
||||||
- `handle()` **must** return a `Response` (on success) or an `Error` (on failure)
|
|
||||||
|
|
||||||
## Notification Handlers
|
|
||||||
|
|
||||||
Handle JSON-RPC notifications (messages without an `id` that don't expect a response). Notification handlers **do not**
|
|
||||||
return anything - they perform side effects only.
|
|
||||||
|
|
||||||
Attach notification handlers with `addNotificationHandler()` (single) or `addNotificationHandlers()` (multiple):
|
|
||||||
|
|
||||||
```php
|
|
||||||
// Handlers are your own classes implementing NotificationHandlerInterface;
|
|
||||||
// the SDK ships only its internal ones.
|
|
||||||
$server = Server::builder()
|
|
||||||
->addNotificationHandler(new AuditNotificationHandler($auditLog))
|
|
||||||
->addNotificationHandlers([
|
|
||||||
new MetricsNotificationHandler($metrics),
|
|
||||||
new CancellationNotificationHandler(),
|
|
||||||
])
|
|
||||||
->build();
|
|
||||||
```
|
|
||||||
|
|
||||||
Notification handlers implement `NotificationHandlerInterface`:
|
|
||||||
|
|
||||||
```php
|
|
||||||
use Mcp\Schema\JsonRpc\Notification;
|
|
||||||
use Mcp\Server\Handler\Notification\NotificationHandlerInterface;
|
|
||||||
use Mcp\Server\Session\SessionInterface;
|
|
||||||
|
|
||||||
interface NotificationHandlerInterface
|
|
||||||
{
|
|
||||||
public function supports(Notification $notification): bool;
|
|
||||||
|
|
||||||
public function handle(Notification $notification, SessionInterface $session): void;
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
- `supports()` decides if the handler should process the incoming notification
|
|
||||||
- `handle()` performs side effects but **does not** return a value (notifications have no response)
|
|
||||||
|
|
||||||
## Key Differences
|
|
||||||
|
|
||||||
| Handler Type | Interface | Returns | Use Case |
|
|
||||||
|-------------|-----------|---------|----------|
|
|
||||||
| Request Handler | `RequestHandlerInterface` | `Response\|Error` | Handle requests that need responses (e.g., `tools/list`, `tools/call`) |
|
|
||||||
| Notification Handler | `NotificationHandlerInterface` | `void` | Handle fire-and-forget notifications (e.g., `notifications/initialized`, `notifications/progress`) |
|
|
||||||
|
|
||||||

custom `tools/list` and `tools/call` request handlers independently of the registry.

# Protocol Extensions
|
|
||||||
|
|
||||||
MCP protocol extensions advertise additional, optional capabilities alongside the regular ones —
|
|
||||||
during the `initialize` handshake, or on revision `2026-07-28` (which has no handshake) inside the
|
|
||||||
capabilities that travel with every request. A server opts in via `Builder::enableExtension()` and
|
|
||||||
the SDK places the advertisement correctly for whichever era the client speaks:
|
|
||||||
|
|
||||||
```php
|
|
||||||
use Mcp\Schema\Extension\Apps\McpApps;
|
|
||||||
use Mcp\Server;
|
|
||||||
|
|
||||||
$server = Server::builder()
|
|
||||||
->setServerInfo('My Server', '1.0.0')
|
|
||||||
->enableExtension(new McpApps())
|
|
||||||
->build();
|
|
||||||
```
|
|
||||||
|
|
||||||
Pass one or more `ExtensionInterface` instances; multiple extensions can
|
|
||||||
be enabled in a single call. Enabling the same extension twice throws a
|
|
||||||
`LogicException`.
|
|
||||||
|
|
||||||
Clients (hosts) advertise the extensions they support the same way, via
|
|
||||||
`Client\Builder::enableExtension()`; the payload lands under
|
|
||||||
`capabilities.extensions` in the initialize request — or, on a modern revision,
|
|
||||||
under the client capabilities carried in each request's `_meta` envelope.
|
|
||||||
|
|
||||||
> Note: extensions enabled via `enableExtension()` are merged into the
|
|
||||||
> `extensions` capability even when you supply your own `ServerCapabilities` /
|
|
||||||
> `ClientCapabilities` via `setCapabilities()`. An enabled extension overrides
|
|
||||||
> any entry under the same id already present in those capabilities.
|
|
||||||
|
|
||||||
## Checking what the client negotiated
|
|
||||||
|
|
||||||
An extension is only in effect when both sides advertise it. On the server, a
|
|
||||||
handler can ask the `ClientGateway` from the injected `RequestContext` whether the
|
|
||||||
connected client did:
|
|
||||||
|
|
||||||
```php
|
|
||||||
use Mcp\Schema\Extension\Apps\McpApps;
|
|
||||||
use Mcp\Server\RequestContext;
|
|
||||||
|
|
||||||
public function getWeather(string $city, RequestContext $context): string
|
|
||||||
{
|
|
||||||
if (!$context->getClientGateway()->supportsExtension(McpApps::EXTENSION_ID)) {
|
|
||||||
// text-only fallback for hosts without MCP Apps support
|
|
||||||
}
|
|
||||||
// ...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
## MCP Apps (`io.modelcontextprotocol/ui`)
|
|
||||||
|
|
||||||
The [MCP Apps extension][ext-apps] lets servers expose interactive HTML UIs as
|
|
||||||
resources. Clients that support it render them in sandboxed iframes and bridge
|
|
||||||
tool calls between the iframe (the *View*) and the server via the host.
|
|
||||||
|
|
||||||
A UI consists of two pieces wired together by `_meta.ui`:
|
|
||||||
|
|
||||||
1. **A resource** with URI scheme `ui://` and MIME type
|
|
||||||
`text/html;profile=mcp-app`, returning the HTML body.
|
|
||||||
2. **A tool** linked to that resource via `UiToolMeta`, so the client knows to
|
|
||||||
open the UI when the tool is invoked.
|
|
||||||
|
|
||||||
```php
|
|
||||||
use Mcp\Schema\Content\TextResourceContents;
|
|
||||||
use Mcp\Schema\Extension\Apps\McpApps;
|
|
||||||
use Mcp\Schema\Extension\Apps\ToolVisibility;
|
|
||||||
use Mcp\Schema\Extension\Apps\UiResourceContentMeta;
|
|
||||||
use Mcp\Schema\Extension\Apps\UiResourceCsp;
|
|
||||||
use Mcp\Schema\Extension\Apps\UiResourcePermissions;
|
|
||||||
use Mcp\Schema\Extension\Apps\UiToolMeta;
|
|
||||||
|
|
||||||
$server = Server::builder()
|
|
||||||
->enableExtension(new McpApps())
|
|
||||||
->addResource(
|
|
||||||
fn () => new TextResourceContents(
|
|
||||||
uri: 'ui://my-app',
|
|
||||||
mimeType: McpApps::MIME_TYPE,
|
|
||||||
text: file_get_contents(__DIR__.'/app.html'),
|
|
||||||
meta: ['ui' => new UiResourceContentMeta(
|
|
||||||
csp: new UiResourceCsp(connectDomains: ['https://api.example.com']),
|
|
||||||
permissions: new UiResourcePermissions(geolocation: true),
|
|
||||||
prefersBorder: true,
|
|
||||||
)],
|
|
||||||
),
|
|
||||||
'ui://my-app',
|
|
||||||
mimeType: McpApps::MIME_TYPE,
|
|
||||||
meta: ['ui' => McpApps::resourceMarker()],
|
|
||||||
)
|
|
||||||
->addTool(
|
|
||||||
$myToolHandler,
|
|
||||||
'my_tool',
|
|
||||||
meta: ['ui' => new UiToolMeta(
|
|
||||||
resourceUri: 'ui://my-app',
|
|
||||||
visibility: [ToolVisibility::Model, ToolVisibility::App],
|
|
||||||
)],
|
|
||||||
)
|
|
||||||
->build();
|
|
||||||
```
|
|
||||||
|
|
||||||
Note the two distinct `_meta.ui` shapes: the resource *descriptor* (its
|
|
||||||
`resources/list` entry) carries only an empty marker — `McpApps::resourceMarker()` —
|
|
||||||
flagging it as an MCP App, while the resource *content* returned by `resources/read`
|
|
||||||
carries the structured `UiResourceContentMeta` with the actual CSP and permission
|
|
||||||
configuration.
|
|
||||||
|
|
||||||
### Attribute-based discovery
|
|
||||||
|
|
||||||
The same linkage works with `#[McpResource]` / `#[McpTool]`, since both accept a
|
|
||||||
`meta` array and PHP allows `new` in attribute arguments. The one difference is the
|
|
||||||
descriptor marker: `McpApps::resourceMarker()` is a method call and cannot appear
|
|
||||||
in an attribute, so spell it as `new \stdClass()` there.
|
|
||||||
|
|
||||||
```php
|
|
||||||
use Mcp\Capability\Attribute\McpResource;
|
|
||||||
use Mcp\Capability\Attribute\McpTool;
|
|
||||||
use Mcp\Schema\Extension\Apps\McpApps;
|
|
||||||
use Mcp\Schema\Extension\Apps\ToolVisibility;
|
|
||||||
use Mcp\Schema\Extension\Apps\UiToolMeta;
|
|
||||||
|
|
||||||
final class WeatherApp
|
|
||||||
{
|
|
||||||
#[McpResource(uri: 'ui://my-app', mimeType: McpApps::MIME_TYPE, meta: ['ui' => new \stdClass()])]
|
|
||||||
public function view(): TextResourceContents { /* as above */ }
|
|
||||||
|
|
||||||
#[McpTool(name: 'my_tool', meta: ['ui' => new UiToolMeta(resourceUri: 'ui://my-app', visibility: [ToolVisibility::Model, ToolVisibility::App])])]
|
|
||||||
public function myTool(string $city): string { /* ... */ }
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Server-side DTOs
|
|
||||||
|
|
||||||
| Class | Purpose |
|
|
||||||
| --- | --- |
|
|
||||||
| `McpApps` | Extension marker; provides `EXTENSION_ID`, `MIME_TYPE`, `URI_SCHEME` constants. |
|
|
||||||
| `UiToolMeta` | Tool `_meta.ui` payload: `resourceUri` + `visibility`. |
|
|
||||||
| `ToolVisibility` | Enum: `Model`, `App`. |
|
|
||||||
| `UiResourceContentMeta` | Resource content `_meta.ui`: `csp`, `permissions`, `domain`, `prefersBorder`. |
|
|
||||||
| `UiResourceCsp` | CSP allow-lists: `connectDomains`, `resourceDomains`, `frameDomains`, `baseUriDomains`. |
|
|
||||||
| `UiResourcePermissions` | Sandbox permissions: `camera`, `microphone`, `geolocation`, `clipboardWrite`. |
|
|
||||||
|
|
||||||
### Writing the HTML view
|
|
||||||
|
|
||||||
The View and host exchange `JSONRPCMessage` **objects** (not JSON strings) via
|
|
||||||
`window.parent.postMessage`. Before the host forwards `tools/call`,
|
|
||||||
`tool-input`, or `tool-result`, the View must complete the spec-mandated
|
|
||||||
handshake:
|
|
||||||
|
|
||||||
1. View → Host: `ui/initialize` request
|
|
||||||
2. Host → View: response with `hostCapabilities`, `hostInfo`, `hostContext`
|
|
||||||
3. View → Host: `ui/notifications/initialized`
|
|
||||||
4. View → Host: `ui/notifications/size-changed` whenever the iframe wants to
|
|
||||||
resize
|
|
||||||
|
|
||||||
See the [`ext-apps` repository][ext-apps] for the full protocol, official
|
|
||||||
TypeScript SDK (`@modelcontextprotocol/ext-apps`), and view-side examples. A
|
|
||||||
