Cannot configure Remote GitHub MCP Server in ChatGPT (OAuth discovery error)

[J3m5]

Summary

Attempting to add the remote GitHub MCP server as a custom connector in ChatGPT fails during OAuth setup with the message: “Error fetching OAuth configuration.”

Per the README, the remote server URL is https://api.githubcopilot.com/mcp/, and OAuth is listed as supported for compatible MCP hosts. ChatGPT appears unable to complete OAuth discovery/handshake.

Steps to Reproduce

1. In ChatGPT (Plus/Pro or higher):
2. Go to Settings → Connectors → Create.
3. Enter a name and set MCP Server URL to: https://api.githubcopilot.com/mcp/
4. Leave Authentication as OAuth.
5. Check “I trust this application.”
6. Click Create.

Expected

The GitHub MCP server is added and becomes available as a connector (OAuth flow completes).

Actual

ChatGPT shows “Error fetching OAuth configuration.” The connector is not created.

Environment

• Product: ChatGPT (web)
• Plan: Plus/Pro (individual)
• MCP Server URL: https://api.githubcopilot.com/mcp/

Hi 👋 GitHub currently does not support Dynamic Client Registration, that's why adding MCP this way won't work. Chat GPT has a separate integration with GitHub API, I suggest you try that:

Hi, thanks for clarifying. I’m aware of the built-in GitHub integration, but it currently only works in Agent and Deep Research modes, not as a general MCP connector.

Is support for Dynamic Client Registration on the roadmap for the GitHub MCP server?

We are committed to bring DCR support in the future.

Have you tried a proxy server between ChatGPT and Github Remote MCP? I've having the same issue.

OAuth in ChatGPT seems to work now, but organization project access doesn't seem to work. #1325
