# Grain MCP: Use Grain in Slack and Email

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

Connect the Grain MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “What objections came up in this week's sales calls?”

Grain records your meetings and keeps notes, transcripts and clips. Connect the Grain MCP server to Maito once, and everyone on your team can use Grain from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

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

## How to connect Grain

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

## Questions

### What is the Grain MCP server URL?

Grain publishes it at https://api.grain.com/\_/mcp, and it signs in with OAuth, so there's no key to copy.

### Can I use the Grain 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 Grain?

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

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

No. If a request needs Grain 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 Grain?

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