# Instantly MCP: Use Instantly in Slack and Email

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

Connect the Instantly MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “Which replies from yesterday are interested and need a follow-up?”

Instantly runs cold email campaigns and keeps the leads and replies. Connect the Instantly MCP server to Maito once, and everyone on your team can use Instantly from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

## How to connect Instantly

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

## Questions

### What is the Instantly MCP server URL?

Instantly publishes it at https://mcp.instantly.ai/mcp, and it signs in with OAuth, so there's no key to copy.

### Can I use the Instantly 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 Instantly?

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

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

No. If a request needs Instantly 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 Instantly?

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