Connect to ChatGPT

Once your MCP server is running (see Setup MCP Server), follow these steps to connect it to ChatGPT.

1. Open the Connector Settings

Go to chatgpt.com/apps → Settings → Connectors → Advanced and click Add Connector.

2. Fill In Basic Details

Field	Value
Icon	Right-click and save:
Name	FeynmanLM
MCP Server URL	Your Tailscale URL with /mcp appended, e.g. https://your-mac.your-tailnet.ts.net/mcp
Authentication	OAuth

3. Configure Advanced Settings

Click Advanced settings to expand the OAuth options.

Client Registration

• Registration method: Select User-Defined OAuth Client
• OAuth Client ID: Paste the Client ID from FeynmanLM → Studio → Connect MCP
• OAuth Client Secret: Paste the Secret from FeynmanLM → Studio → Connect MCP
• Token endpoint auth method: Select client_secret_post

OpenID Support

• Uncheck "OIDC enabled" — FeynmanLM uses plain OAuth 2.1, not OpenID Connect.

OAuth Endpoints

These should auto-populate from your MCP Server URL. Verify they point at your Tailscale URL (not feynmanlm.com):

Field	Value
Auth URL	https://your-mac.your-tailnet.ts.net/oauth/authorize
Token URL	https://your-mac.your-tailnet.ts.net/oauth/token
Authorization server base	https://your-mac.your-tailnet.ts.net

4. Save

Check the "I understand and want to continue" box and click Create.

Try It Out

Ask ChatGPT things like:

• "What sources do I have in my knowledge base?"
• "Read my latest source and explain the key concepts."
• "Search for sources about oxidative phosphorylation."
• "Test me on this paper using Socratic questioning."

See Learning with MCP for more detailed learning workflows.

Disconnecting

Go to Settings → Connectors, find FeynmanLM, and click Remove.
