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

Connect the Eraser MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “Draw a sequence diagram of our checkout flow from this description.”

Eraser is where teams make technical diagrams and design docs. Connect the Eraser MCP server to Maito once, and everyone on your team can use Eraser from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

## How to connect Eraser

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

## Questions

### What is the Eraser MCP server URL?

Eraser publishes it at https://app.eraser.io/api/mcp, and it signs in with OAuth, so there's no key to copy.

### Can I use the Eraser 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 Eraser?

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

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

No. If a request needs Eraser 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 Eraser?

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