Connect the ClickHouse MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “How many signups did we get per day last week?”

ClickHouse Cloud is a fast analytics database for your event and product data. Connect the ClickHouse MCP server to Maito once, and everyone on your team can use ClickHouse from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

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

## How to connect ClickHouse

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

## Questions

### What is the ClickHouse MCP server URL?

ClickHouse publishes it at https://mcp.clickhouse.cloud/mcp, and it signs in with OAuth, so there's no key to copy.

### Can I use the ClickHouse 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 ClickHouse?

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

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

No. If a request needs ClickHouse 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 ClickHouse?

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