Connect ChatGPT

Not possible today. Here is exactly why, so you know what to watch for rather than guessing.

ChatGPT connectors require OAuth — this server's OAuth path is not live yet

ChatGPT's custom-connector spec requires OAuth 2.1 with Dynamic Client Registration for every connector; a static Authorization: Bearer header — the mechanism Claude Code, Claude Desktop, and Cursor all use to connect to PMM Tools today — is not accepted for connectors at all.

The PMM Tools MCP server has started building OAuth support (discovery metadata is live at /.well-known/oauth-protected-resource/api/mcp), but token verification is not functional yet: the app still signs its session tokens with a legacy symmetric (HS256) secret, so the public key set an OAuth client needs to verify a token is currently empty, and every OAuth token fails closed. Until asymmetric signing is enabled, there is no working credential ChatGPT could use — this isn't a ChatGPT-side setting to change.

In the meantime, Claude Code, Claude Desktop, and Cursor all connect today with an API key. See the full tool list and plan limits for what's available once you're connected on one of those.
