TMCP: A New Way to Build MCP servers in TS
summary
Claims a minimal TypeScript MCP server library called TMCP that replaces the official SDK with a lightweight JSON-RPC core using JSON-RPC 2.0, adapters for validators like Zod v4/Valibot, and separate STDIO/HTTP transports. Demonstrations show working tools, resources, elicitation and session managers backed by Redis/Postgres, plus helper utils (tool.text). Size and dependency wins are concrete: 325 KB vs 4 MB, 5 direct vs 17 direct deps and 5 vs 93 total, and ~608K weekly installs compared to millions.
