# Crossbeam MCP: Use Crossbeam in Slack and Email

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

Connect the Crossbeam MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “Which of our open opportunities are customers of Bright Labs?”

Crossbeam shows overlaps between your accounts and your partners' accounts. Connect the Crossbeam MCP server to Maito once, and everyone on your team can use Crossbeam from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

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

## How to connect Crossbeam

Open Connections in your workspace and choose Connect next to Crossbeam. You sign in to Crossbeam 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 Crossbeam from then on. Or skip ahead and ask for the work: Maito sends you a link if Crossbeam isn't connected yet.

## Questions

### What is the Crossbeam MCP server URL?

Crossbeam publishes it at https://mcp.crossbeam.com/, and it signs in with OAuth, so there's no key to copy.

### Can I use the Crossbeam 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 Crossbeam?

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

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

No. If a request needs Crossbeam 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 Crossbeam?

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