BILL MCP server: connect BILL to Claude and ChatGPT

BILL is reached through its API with credentials that can only read your administrator authorises. Junction builds only read requests, applies the API's paging and rate limits, and adds its own limits and sensitivity rules on top.

• “Which bills are waiting for approval, and with whom?”
• “What are we due to pay in the next 14 days?”
• “Which vendors did we pay most this quarter?”

Answers come from your own system, with the source rows and the time the data was last updated.

• BILL is widely used (markets: United States) and readable without writing to it. We build each mapping from the vendor's own reference and check it with a customer who runs the system.
• Integration routes found in our research: REST API, Webhooks.
• When we researched this in October 2026 we found no MCP server from the vendor.
• Payroll and personal data are denied by default.
