# Metal MCP: Use Metal in Slack and Email

Source: https://maito.app/integrations/metal

Connect the Metal MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “Which deals in our pipeline are in the diligence stage?”

Metal holds deal data for investment firms: companies, deals and pipeline research. Connect the Metal MCP server to Maito once, and everyone on your team can use Metal from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

What do we know about Bright Labs from past deal notes?

Maito uses Metal to do the work and replies where you asked.

## How to connect Metal

Open Connections in your workspace and choose Connect next to Metal. You sign in to Metal in a new tab, and that's the whole setup. Name the account and choose Workspace under who can use it. That's the only time anyone signs in: your whole team, shared chats and Loops can use Metal from then on. Or skip ahead and ask for the work: Maito sends you a link if Metal isn't connected yet.

## Questions

### What is the Metal MCP server URL?

Metal publishes it at https://mcp.metal.ai/mcp, and it signs in with OAuth, so there's no key to copy.

### Can I use the Metal MCP server from Slack?

Yes. Connect it to Maito once, then mention Maito in any Slack channel or send it a direct message. The same connection works by email and from Claude, ChatGPT, Cursor, Codex, Grok or Muse.

### Does everyone on my team have to connect Metal?

No. One person connects it once and chooses Workspace. Then everyone in the workspace, shared chats and Loops can use Metal, without signing in themselves. Choose Only me instead to keep it to your own chats.

### Do I have to connect Metal before I ask?

No. If a request needs Metal and it isn't connected yet, your agent sends you a link. Connect it, and the work picks up where it stopped.

### Can I limit what Maito does in Metal?

Yes. After you connect, turn off any Metal tools you don't want Maito to use, such as the ones that change data. Tools Metal adds later stay off until you turn them on.
