Agentlang apps can now act as MCP servers, allowing LLM clients to discover and invoke tools/resources over Streamable HTTP transport. - Extract shared API handlers (handlers.ts) from http.ts for reuse by both HTTP and MCP layers (evaluateEvent, queryEntity, createEntity, updateEntity, deleteEntity, verifyAuth, normalizedResult) - Add MCP server module (mcp.ts) with tool registration from public events, resource registration from entities, per-session transport management, and JSON Schema conversion from RecordSchema - Add MCP config section to ConfigSchema (enabled, path, name, version) - Add setMcpEndpointsUpdater for dynamic tool/resource updates - Wire authentication through MCP transport via req.auth -> extra.authInfo with per-tool and per-resource auth checks using shared verifyAuth
- Add resource templates (ListResourceTemplates handler) so clients can
fetch individual entities by ID via {scheme}://{module}/{entity}/{id}
- Extend ReadResource to parse template URIs and query single entities
- Replace hardcoded agentlang:// scheme with configurable uriScheme
(defaults to app name)
- Add TTL-based stale session cleanup with configurable sessionTtl
(default 30 min), skipped in stateless mode
- Declare listChanged capability for tools and resources
