If your MCP server uses OAuth, every directory thinks it has zero tools

We shipped a remote MCP server, registered it everywhere, and then noticed something odd: every directory listed it as having no tools at all . Not the wrong tools. Not a stale count. Zero.

  • Tools/list JSON-RPC method requires authenticated user
  • Separating public and authenticated methods resolves issue
