# PlanetScale MCP: Use PlanetScale in Slack and Email

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

Connect the PlanetScale MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “How many new signups are in the users table since Monday?”

PlanetScale hosts your Postgres and MySQL databases. Connect the PlanetScale MCP server to Maito once, and everyone on your team can use PlanetScale from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

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

## How to connect PlanetScale

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

## Questions

### What is the PlanetScale MCP server URL?

PlanetScale publishes it at https://mcp.pscale.dev/mcp/planetscale, and it signs in with OAuth, so there's no key to copy.

### Can I use the PlanetScale 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 PlanetScale?

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

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

No. If a request needs PlanetScale 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 PlanetScale?

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