Prerequisites
- An organization admin has enabled MCP (see overview).
- A ChatGPT plan that supports custom connectors / developer mode. Availability and admin controls vary by plan (Plus, Pro, Business, Enterprise).
Add the connector
Open connector settings
In ChatGPT, go to Settings → Connectors (under Apps & Connectors). If you’re adding your own server, enable Developer mode under Advanced.
Create a custom connector
Click Create (or Add custom connector) and enter:
- Name — Metal
- MCP server URL —
https://mcp.metal.ai/mcp - Authentication — OAuth
Connect and sign in
Create the connector, then Connect. ChatGPT opens a browser window to sign in with your Metal account. Approve access, and choose an organization if prompted.
Verify
Ask ChatGPT something that uses your data, for example:Use the Metal connector to find companies in my pipeline tagged as targets and summarize them.
Troubleshooting
- Can’t add a connector — custom connectors and developer mode depend on your plan and may be restricted by a workspace admin.
- Connection or sign-in fails — confirm an admin enabled MCP under Settings → Organization → API & MCP Access, and that the URL is exactly
https://mcp.metal.ai/mcp.
