# AgentMail MCP: Use AgentMail in Slack and Email

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

Connect the AgentMail MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “Set up a new inbox for vendor invoices.”

AgentMail gives agents their own email inboxes to send, receive and reply from. Connect the AgentMail MCP server to Maito once, and everyone on your team can use AgentMail from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

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

## How to connect AgentMail

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

## Questions

### What is the AgentMail MCP server URL?

AgentMail, Inc. publishes it at https://mcp.agentmail.to/mcp, and it signs in with OAuth, so there's no key to copy.

### Can I use the AgentMail 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 AgentMail?

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

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

No. If a request needs AgentMail 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 AgentMail?

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