#301 added the `title` field to the `Resource`/`ResourceTemplate` schema
classes and the `McpResource`/`McpResourceTemplate` attributes, but the
manual registration methods on `Builder` were never updated — so manual
registration could not set a resource title, unlike tools and prompts.
Add a `$title` parameter between `$name` and `$description` (matching
`addTool()`/`addPrompt()`) and propagate it through `ArrayLoader` when
constructing the `Resource`/`ResourceTemplate` objects.

The MCP specification (2025-11-25) defines an optional title field for
Resource and ResourceTemplate as a human-readable display label, distinct
from name (a short identifier). Tool and Prompt already implement this
field; Resource and ResourceTemplate were missing it.
Changes:
- Add title parameter to Resource and ResourceTemplate constructors
- Add title to fromArray(), jsonSerialize(), and PHPStan type arrays
- Add title to McpResource and McpResourceTemplate attributes
- Pass title through Discoverer when constructing schema objects
- Add tests for deserialization, serialization, and null omission
Fixes#296
Drop the isManual flag from ElementReference and the discovery-state methods
from RegistryInterface. The Registry becomes a flat last-write-wins map;
DiscoveryLoader owns its own owned-set bookkeeping so re-running discovery
only removes elements it itself contributed. Adds ChainLoader for explicit
composition. Manual-over-discovered precedence is preserved via loader
ordering, not a flag on the reference.
* Add optional namePatterns capability to discovery so that the default scan for `*.php` files can be overridden.
* add default to namePatterns docs
* add an error check if we manage to pass in an empty list of patterns
* add unit tests (and a static entry to classmap for composer.json so it autoloads from a non .php file for the test)
* run php-cs-fixer
* change how default namePatterns are set and make sure all the annotations are correct
* Fix bad whitespace

* feat(schema): add top-level title to Tool
Mirror PR #278's Prompt change for Tool:
- Add optional ?string $title to Mcp\Schema\Tool between $name
and $inputSchema. fromArray() now reads $data['title'];
jsonSerialize() emits 'title' right after 'name'. The
@phpstan-type ToolData gains title?: string.
- Add ?string $title to the #[McpTool] attribute between $name
and $description.
- Note ToolAnnotations::$title as deprecated-for-display in
favor of Tool::$title per MCP spec 2025-06-18 (PHPDoc only,
field retained for BC).
Phase 1 of plan 01--tool-title-spec-compliance. Later phases
update Discoverer, Builder::addTool(), ArrayLoader, and the
conformance fixture to match the new signature.
* feat(server): thread title through discovery
- Discoverer::processMethod() now propagates McpTool::$title
into every discovered Tool via named arguments.
- Builder::addTool() accepts ?string $title between $name and
$description. [BC Break] positional callers passing the old
$description as 3rd positional argument must switch to named
arguments, matching the precedent set for addPrompt() in
0.5.0.
- tests/Conformance/server.php migrated to named-argument form
for every addTool() call.
Phase 2 of plan 01--tool-title-spec-compliance.
* feat(loader): forward title in ArrayLoader
ArrayLoader now reads 'title' from each tool config entry and
passes it into the Tool constructor, completing the wiring
from Builder::addTool() through array-driven registration.
The $tools @param array-shape typedef gains title: ?string
between name and description.
Phase 3 of plan 01--tool-title-spec-compliance.
* test(schema): cover Tool.title end-to-end
- New tests/Unit/Schema/ToolTest.php: constructor round-trip,
jsonSerialize key-order when title set vs null, fromArray
tolerance.
- New tests/Unit/Capability/Discovery/DiscovererToolTitleTest
plus a TitleFixture class verifying McpTool(title: ...)
propagates through discovery into the registered Tool.
- New tests/Unit/Capability/Registry/Loader/ArrayLoader...
test verifying array-driven title propagation.
- Extend McpToolTest for title named-arg and default-null.
- Extend BuilderTest with addTool(title: 't') propagation.
- Update tests/Unit/.../RegistryTest, CallToolHandlerTest,
ListToolsHandlerTest and examples/.../server.php
new Tool(...) call sites to pass title (named args) so
they match the new constructor signature.
- CHANGELOG 0.6.0 section: feature bullet + [BC Break]
note for addTool() signature, mirroring 0.5.0 Prompt
entries.
- docs/server-builder.md: addTool() row and prose now
list title? between name and description.
Phase 4 of plan 01--tool-title-spec-compliance. All 730
phpunit tests pass; remaining phpstan warnings are
pre-existing and unrelated to Tool.title.
* refactor(schema): make Tool.title non-BC-breaking
Move `title` to the end of the Tool, Builder::addTool, and McpTool
attribute constructors with a default of null. This preserves
positional-argument compatibility and removes the need for
`title: null` boilerplate at call sites. JSON serialization order
(name, title, inputSchema, ...) is unchanged.
Also tighten the new tests: parameterize ToolTest with data
providers, fold the Discoverer title fixture into the existing
DiscoverableToolHandler, and drop the reflection-heavy Builder
test that overlapped with ArrayLoaderToolTitleTest.
* fix: move title after name

The MCP 2025-11-25 specification defines an optional `title` property on
Prompt for human-readable display in UI contexts, distinct from the
programmatic `name` identifier. This was missing from the SDK.
BC Break: Builder::addPrompt() signature changed — $title parameter added
between $name and $description. Callers using positional arguments for
$description must switch to named arguments.
Closes#276
Split formatting logic from Reference classes into dedicated formatter classes:
- ToolResultFormatter: Formats tool execution results into Content items
- PromptResultFormatter: Formats prompt results into PromptMessage items
- ResourceResultFormatter: Formats resource results into ResourceContents items
This refactor:
- Eliminates 122 lines of code duplication between ResourceReference and
ResourceTemplateReference (identical formatting logic)
- Improves code organization by separating formatting concerns from
capability reference management
- Makes formatters independently testable and reusable
- Reduces Reference classes by ~450 lines while maintaining all functionality
Changes:
- Create src/Capability/Formatter/* with three formatter classes
- Update Reference classes to delegate to formatters instead of inline logic
- Add comprehensive test coverage for all formatter classes
- All existing tests pass; no behavioral changes
* Remove `getSummary` method and update descriptions in snapshots and code
