Buyer checklist

What to verify before adopting

  1. Which MCP role does the project serve: server, client, gateway, registry, or development tooling?
  2. Are authentication, permission, and secret-handling boundaries documented?
  3. Does the release history show compatibility work as the protocol evolves?
