MCPT-01 Servers answer tools/list
Live introspection — CLI-only, behind the explicit --mcp-live flag.
Why it matters
A configured server that can't complete the MCP handshake is dead weight: every session carries its config, but no tool ever becomes available — and the failure is usually silent.
How to fix it
Run the server's command by hand and fix what breaks (missing binary, bad args, missing env). It must complete initialize → initialized → tools/list over stdio.
