ChatGPT

Hosted URL, no install
  1. Status: unknown. Not tested.
  2. ChatGPT accepts remote MCP servers only in developer mode on some plans.
  3. The server publishes OAuth discovery documents (/.well-known/oauth-protected-resource returns 200), so the URL form may work. This isn't verified.

Test status: unknown
