add new sample: kotlinlang mcp server with 2 tools
- search
- get_page
## How Has This Been Tested?
inspector/unit
## Breaking Changes
none
## Checklist
- [x] I have read the [MCP
Documentation](https://modelcontextprotocol.io)
- [x] My code follows the repository's style guidelines
- [x] New and existing tests pass locally
- [x] I have added appropriate error handling
- [x] I have added or updated documentation as needed
<!-- Provide a brief summary of your changes -->
Add support for MCP extension negotiation during the initialize
handshake, as defined in the MCP extensions specification. Clients and
servers can now advertise supported extensions via a new `extensions:
Map<String, JsonObject>?` field on their respective capabilities
objects.
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
Extensions are supported part of the [MCP spec
](https://modelcontextprotocol.io/extensions/overview) and are available
in other language libraries e.g. [Golang
](862d78a265/mcp/protocol.go (L215)).
## How Has This Been Tested?
Existing and added unit tests
## Breaking Changes
<!-- Will users need to update their code or configurations? -->
Adding a new field to existing ClientCapabilities and ServerCapabilities
fields will break already compiled clients. They will need to recompile
on upgrading.
## Types of changes
<!-- What types of changes does your code introduce? Put an `x` in all
the boxes that apply: -->
- [ ] Bug fix (non-breaking change which fixes an issue)
- [x] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update

<blockquote>
<h2>1.11.0</h2>
<p>This release is based on Kotlin 2.3.20 and provides a new Json
exceptions API and some bugfixes and improvements.</p>
<h2>Expose Json exceptions structure</h2>
<p>To make working with exceptions easier and providing proper error
codes in e.g., REST APIs,
classes <code>JsonException</code>, <code>JsonDecodingException</code>,
and <code>JsonEncodingException</code> are now public.
They have relevant public properties, such as <code>shortMessage</code>,
<code>path</code>, <code>offset</code>, and others.
This API is currently experimental, and we're going to improve it
further in the subsequent releases.
See the linked issues for the details: <a
href="https://redirect.github.com/Kotlin/kotlinx.serialization/issues/1930">#1930</a>,
<a
href="https://redirect.github.com/Kotlin/kotlinx.serialization/issues/1877">#1877</a>.</p>
<h2>Ability to hide user input from exception messages for
security/privacy reasons.</h2>
<p>Historically, exception messages in kotlinx.serialization often
included the input Json itself for debuggability reason.
Such behavior may pose additional challenges for logging, analytics, and
other systems, since
a system is not always allowed to store user data due to
privacy/security reasons, which imposes additional sanitation logic.
To address this issue, a new property
<code>exceptionsWithDebugInfo</code> is added to
<code>JsonConfiguration</code>.
Disable it to hide user input from exception messages.
IMPORTANT: This behavior will be enabled by default when this property
becomes stable.
See <a
href="https://redirect.github.com/Kotlin/kotlinx.serialization/issues/2590">#2590</a>
for more details.</p>
<h2>Bugfixes and improvements</h2>
<ul>
<li>CBOR: Relax value range check when decoding numbers (<a
href="https://redirect.github.com/Kotlin/kotlinx.serialization/issues/3167">#3167</a>)</li>
<li>Use a specialized writeDecimalLong method for IO stream integrations

Remove Codecov configuration and CI steps for uploading coverage/test
reports.
## Motivation and Context
- Codecov integration relies on third-party credentials
- Codecov has not demonstrated clear value for the project:
- Coverage analysis is already handled by kover, which runs locally and
in CI
- PR reviews still require manual inspection of tests regardless of
codecov reports
- Codecov flaky test detection is unreliable, it marks 3325 out of all
tests as flaky with similar failure rates, making the signal useless
(https://app.codecov.io/gh/modelcontextprotocol/kotlin-sdk/tests)
Remove unused OpenAPI Generator plugin, its configuration, and the
`.openapi-generator-ignore` file.

Bumps [hono](https://github.com/honojs/hono) from 4.12.9 to 4.12.12.
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/honojs/hono/releases">hono's
releases</a>.</em></p>
<blockquote>
<h2>v4.12.12</h2>
<h2>Security fixes</h2>
<p>This release includes fixes for the following security issues:</p>
<h3>Middleware bypass via repeated slashes in serveStatic</h3>
<p>Affects: Serve Static middleware. Fixes a path normalization
inconsistency where repeated slashes (<code>//</code>) could bypass
route-based middleware protections and allow access to protected static
files. GHSA-wmmm-f939-6g9c</p>
<h3>Path traversal in toSSG() allows writing files outside the output
directory</h3>
<p>Affects: <code>toSSG()</code> for Static Site Generation. Fixes a
path traversal issue where crafted <code>ssgParams</code> values could
write files outside the configured output directory.
GHSA-xf4j-xp2r-rqqx</p>
<h3>Incorrect IP matching in ipRestriction() for IPv4-mapped IPv6
addresses</h3>
<p>Affects: IP Restriction Middleware. Fixes improper handling of
IPv4-mapped IPv6 addresses (e.g. <code>::ffff:127.0.0.1</code>) that
could cause allow/deny rules to be bypassed. GHSA-xpcf-pg52-r92g</p>
<h3>Missing validation of cookie name on write path in setCookie()</h3>
<p>Affects: <code>setCookie()</code>, <code>serialize()</code>, and
<code>serializeSigned()</code> from <code>hono/cookie</code>. Fixes
missing validation of cookie names on the write path, preventing
inconsistent handling between parsing and serialization.
GHSA-26pp-8wgv-hjvm</p>
<h3>Non-breaking space prefix bypass in cookie name handling in
getCookie()</h3>
<p>Affects: <code>getCookie()</code> from <code>hono/cookie</code>.
Fixes a discrepancy in cookie name handling that could allow
attacker-controlled cookies to override legitimate ones and bypass
prefix protections. GHSA-r5rp-j6wh-rvv4</p>
<hr />
<p>Users who use Serve Static, Static Site Generation, Cookie utilities,
or IP restriction middleware are strongly encouraged to upgrade to this
version.</p>

Users currently must manually `install(ContentNegotiation) {
json(McpJson) }` before calling `mcp()`,
`mcpStreamableHttp()`, or `mcpStatelessStreamableHttp()`. Forgetting
this or using the default `json()`
instead of `json(McpJson)` causes silent serialization failures at
runtime (e.g., explicit null fields in JSON-RPC
responses). This PR makes the SDK install it automatically.
Fixes#664
## Changes
- **Core feature** — `mcp()`, `mcpStreamableHttp()`, and
`mcpStatelessStreamableHttp()` now auto-install `ContentNegotiation`
configured with `McpJson`. If the user already installed
`ContentNegotiation`, a warning is logged instead of crashing with
`DuplicatePluginException`.
- **`KtorServerHelpers.kt`** (new) — `installMcpContentNegotiation()`
internal helper with `pluginOrNull` guard and warning
- **`KtorServer.kt`** — calls the helper from all three entry points
- **`build.gradle.kts`** — adds `ktor-server-content-negotiation` and
`ktor-serialization` as `implementation` deps to `kotlin-sdk-server`
- **Removed manual installs** from `ConformanceServer.kt` and
`AbstractStreamableHttpIntegrationTest.kt`.
- **Test infrastructure** — replaced `slf4j-simple` with Logback and use
`ListAppender` (`LogCapture` utility) for deterministic log assertion.
Added `logback-test.xml` matching previous log levels.
- **`StreamableHttpServerConfigurationTest.kt`** (new) — verifies the
warning for all three entry points: `mcpStreamableHttp`,
`mcpStatelessStreamableHttp`, and `mcp` (SSE).
- **README.md** — removed manual `ContentNegotiation` boilerplate from
examples, documented automatic installation, added CORS configuration
snippet for browser-based clients.
- **CI** — added `ktlintCheck` to the Linux build matrix job.

## Summary
Add `maxRequestBodySize` parameter to
`StreamableHttpServerTransport.Configuration`, allowing consumers to set
a custom request body size limit lower than the default 4 MB.
- Add `maxRequestBodySize: Long` property to `Configuration` with a
default of 4 MB (`4,194,304` bytes)
- Replace hardcoded `MAXIMUM_MESSAGE_SIZE` constant with the
configurable value in `parseBody()`
- Use `Long` for content-length comparison to avoid `Int` overflow on
large values
## Motivation and Context
Closes#521
The `StreamableHttpServerTransport` has a hardcoded 4 MB request body
limit. Consumers who need a lower limit currently have to manually count
the request payload size before passing it to the SDK. This change makes
the limit configurable via `Configuration`.
## How Has This Been Tested?
- Existing unit tests continue to pass (default 4 MB behavior unchanged)
- Added `POST with custom max request body size rejects oversized
payload` — verifies `PayloadTooLarge` is returned for payloads exceeding
the custom limit
- Added `POST at exactly custom max request body size is not rejected as
payload too large` — verifies payloads at exactly the limit are not
rejected by the size check
```bash
./gradlew :kotlin-sdk-server:jvmTest --tests "*.StreamableHttpServerTransportTest"
```
## Breaking Changes
None. The new parameter has a default value matching the previous
hardcoded limit.

Add URL mode elicitation support and typed `PrimitiveSchemaDefinition`
hierarchy to align with MCP specification 2025-11-25
closes#540
## How Has This Been Tested?
unit/integration/conformance
## Breaking Changes
- `ElicitRequestParams` changed from `data class` to `sealed interface`.
A deprecated factory function preserves source compatibility for
`ElicitRequestParams(message, requestedSchema)`.
- `RequestedSchema.properties` changed from `JsonObject` to `Map<String,
PrimitiveSchemaDefinition>`.
- `ElicitRequest.requestedSchema` is deprecated, use `(params as
ElicitRequestFormParams).requestedSchema`.
