## How to connect NPI Registry

Open Connections in your workspace and choose Connect next to NPI Registry. It needs no separate sign-in: choose Connect and it's ready. 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 NPI Registry from then on. Or skip ahead and ask for the work: Maito sends you a link if NPI Registry isn't connected yet.

## Questions

### Who publishes the NPI Registry MCP server?

Anthropic, and it needs no sign-in. Maito connects to it for you, so there's no address to copy.

### Can I use the NPI Registry 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 NPI Registry?

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

### Do I have to connect NPI Registry before I ask?

No. If a request needs NPI Registry 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 NPI Registry?

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