* feat(memory): expose knowledge graph as MCP Resource
Register the knowledge graph as a readable MCP Resource at
memory://knowledge-graph, enabling clients to discover and read
the graph via the Resources protocol without invoking a tool.
Mutation tools (create_entities, create_relations, add_observations,
delete_entities, delete_observations, delete_relations) now emit
notifications/resources/updated so subscribed clients see live
graph changes.
Resource registration is extracted into the exported
registerKnowledgeGraphResource() function so it can be unit-tested
in isolation, mirroring the everything server's registration
pattern. New tests assert registerResource is called with the
correct kebab-case name, URI, mime type, and that the handler
returns the graph as JSON in the contents array.
Addresses PR #3323 review feedback:
- kebab-case resource name per CLAUDE.md style guide
- single-line comment per CLAUDE.md style guide
- title metadata for client discoverability
- resource update notifications after mutations
- test coverage matching everything/registrations.test.ts pattern
- README documents the new Resource
* feat(memory): support resources/subscribe for the knowledge-graph resource
PR #3323 emitted notifications/resources/updated after every mutation but
the server only advertised resources.listChanged, so resources/subscribe
returned -32601 and a spec-compliant client could never actually subscribe.
Declare resources.subscribe, add subscribe/unsubscribe request handlers that
track subscribed URIs, and only emit notifications/resources/updated when the
client has subscribed to that URI.
