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

Connect the Trustfull MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “What's the fraud risk for the signup from jane@quickmail.co?”

Trustfull checks emails, phone numbers and other signals to score fraud risk. Connect the Trustfull MCP server to Maito once, and everyone on your team can use Trustfull from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

## How to connect Trustfull

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

## Questions

### What is the Trustfull MCP server URL?

Trustfull publishes it at https://mcp.trustfull.com/connector, and it signs in with OAuth, so there's no key to copy.

### Can I use the Trustfull 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 Trustfull?

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

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

No. If a request needs Trustfull 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 Trustfull?

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