# Clay MCP: Use Clay in Slack and Email

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

Connect the Clay MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “Research these 10 accounts and write one personal line for each.”

Clay finds prospects, researches accounts and personalizes outreach. Connect the Clay MCP server to Maito once, and everyone on your team can use Clay from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

## How to connect Clay

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

## Questions

### What is the Clay MCP server URL?

Clay publishes it at https://api.clay.com/v3/mcp, and it signs in with OAuth, so there's no key to copy.

### Can I use the Clay 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 Clay?

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

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

No. If a request needs Clay 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 Clay?

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