Conversation
- AddCache() extension on IThargaMcpBuilder registers both providers. - CacheResourceProvider exposes four System-scope resources: cache://types, cache://items, cache://health, cache://queue. - CacheToolProvider exposes two System-scope tools: cache.clear_stale and cache.clear_all. - Persist type names are surfaced with the leading 'I' stripped (Memory/Redis/MongoDB/File) to match the Blazor UI convention.
10 tests covering: - Resource provider: lists 4 descriptors; each resource read returns well-formed JSON (types, items, health, queue); unknown URI returns explanatory text. - Tool provider: lists 2 tools; clear_stale and clear_all delegate to ICacheMonitor; unknown tool returns IsError=true. Tharga.Cache.Tests now references Tharga.Cache.Mcp directly to keep the MCP tests alongside the rest of the unit tests.
The sample now exposes the cache via MCP at /mcp:
- AddThargaMcp(mcp => { mcp.Options.RequireAuth = false; mcp.AddCache(); })
- app.UseThargaMcp()
RequireAuth is set to false so the sample is reachable without auth
middleware. Production consumers leave it true and wire their own
authorization.
Per the updated shared-instructions, completed features live in the project's Plan directory ($DOC_ROOT/Tharga/plans/Toolkit/Cache/done/), not inside the repo's .claude/. Moved all 9 archived feature files out and deleted the now-empty .claude/features-done/ folder.

Summary
New package
Tharga.Cache.Mcpthat plugs into Tharga.Mcp and exposes the cache to MCP-aware AI clients.Closes the cross-project request "MCP Provider for Cache monitoring" (Quilt4Net Server / PlutusWave / Florida / Eplicta).
Registration
The naming follows the established
AddMongoDB/AddPlatform/AddCommunicationpattern onIThargaMcpBuilder(the request mentionedAddMcpCache()but consistency wins).Resources
