# Missive MCP: Use Missive in Slack and Email

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

Connect the Missive MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “Which conversations in the support inbox have waited over a day for a reply?”

Missive is a shared inbox where teams read and handle email together. Connect the Missive MCP server to Maito once, and everyone on your team can use Missive from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

## How to connect Missive

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

## Questions

### What is the Missive MCP server URL?

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

### Can I use the Missive 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 Missive?

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

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

No. If a request needs Missive 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 Missive?

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