Connect the BILL MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “Which vendor bills are due in the next 7 days?”

BILL handles bills, payables, receivables, and business spend. Connect the BILL MCP server to Maito once, and everyone on your team can use BILL from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

How much do customers owe us in open invoices?

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

## How to connect BILL

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

## Questions

### What is the BILL MCP server URL?

BILL publishes it at https://gateway.prod.bill.com/ai-mcp-server/v1, and it signs in with OAuth, so there's no key to copy.

### Can I use the BILL 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 BILL?

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

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

No. If a request needs BILL 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 BILL?

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