Write the MCP server code: SDK setup, primitive registration, transport wiring,
error semantics, and protocol behavior. Fixes the failures agents actually hit:
stale/deprecated SDK APIs, stdout-corrupted stdio streams, exceptions where
isError results belong, hand-rolled framing, and transport wiring that breaks
in real clients.
Targets spec revision 2025-11-25 and SDKs verified current on 2026-07-20:
TypeScript @modelcontextprotocol/sdk v1.29 and Python mcp v1.28
