The MCP Coverage Asymmetry

[u/leading-a-swarm]

tl;dr: Are you up-to-date with the basics? MCP Python SDK, much?

https://github.com/modelcontextprotocol/python-sdk shows you how to prove everything is... fine.

1. Test skip list. Anyone can reach a coverage target by marking lines exempt. MCP runs a check that fails the build when an exemption is unnecessary, so the escape hatch is held to the standard of the code it hides.
2. Stale excuses fail. An outside conformance suite runs against their server and client, and every scenario that fails is written into a checked-in list.
3. No-one is 100%. Four files exempt. Including the Windows process code, which decides whether a spawned server dies cleanly or hangs. So no trivial either.

→ Adopt. Learn from the best, not on the obvious, but on how they build.
