Prerequisites
- An organization admin has enabled MCP (see overview).
- A Claude plan that supports custom connectors. On Team and Enterprise plans, an admin may need to allow custom connectors first.
Claude web and desktop
Add Metal as a custom connector in Claude.1
Open connector settings
In Claude, go to Settings → Connectors, then click Add custom connector.
2
Enter the Metal server
Give it a name like Metal and paste the server URL:
3
Connect and sign in
Click Add, then Connect. Claude opens a browser window to sign in with your Metal account. Approve access, and choose an organization if prompted.
4
Enable in a chat
Open the tools/connectors menu in a conversation and make sure Metal is enabled.
Claude Code (CLI)
Add the server with the Claude Code CLI:/mcp to complete the browser sign-in.
Verify
Ask Claude something that uses your data, for example:Use Metal to find recent deals in the industrials sector and list their stages.Claude requests permission to use the Metal tools on first use. Approve it.
Troubleshooting
- “Couldn’t connect”: confirm an admin enabled MCP under Settings → Organization → API & MCP Access, and that the URL is exactly
https://mcp.metal.ai/mcp. - Connector option missing: custom connectors require a supported plan; on Team/Enterprise an admin may need to enable them.
