What causes MCP token expiry in production?

OAuth timeouts (1h-90d), admin revokes, registry rotations like NPM—silent unless you watch.

Pre-flight checks, structured errors (credential_expired tags), secrets store rotation. Fail loud at startup.

Nah—free with Vault Community or Doppler free tier. Manual fixes cost sanity.

AI folks hyped MCP as the glue for agent tools. Reality? Your production server ghosts out at 2AM from expired tokens, and nobody's watching.
