Connect Bill.com to Claude, ChatGPT and Claude Code

Credentials off one Bill.com screen, then an endpoint your client signs into. Nothing to deploy, and nothing to install.

In BILL, go to Settings, then Sync & Integrations, then Manage Developer Keys, and click Generate developer key. Paste the key and the Organization ID shown on that page, with the username and password of a BILL user made just for this. Card spend needs a Spend & Expense API token, which also works alone. PopMCP works out whether it is production or the sandbox.

FAQ

Bill.com MCP server questions

What teams ask before putting Bill.com behind an AI client.

What does PopMCP need to connect Bill.com?

For bills, payments and invoices: a developer key, your Organization ID, and the username and password of a BILL user. The key and the ID are on the same page in BILL, under Settings, Sync & Integrations, Manage Developer Keys, and there is nothing to apply for. For card spend and budgets: a Spend & Expense API token, made by an Admin. Either one works alone, or use both.

Why does it ask for a password?

BILL's API signs in as a user, and it has no sign-in button for other apps to use. Add a separate BILL user just for PopMCP, so your own password stays yours, and give it only the role it needs. The password is stored encrypted and sent only to BILL. You can also use a sync token from Settings, Sync & Integrations, Tokens, in the same two fields, though a sync token cannot pay bills, send invoices or approve.

Why not use BILL's own MCP server?

BILL's own server is in beta and read-only, covers part of the API, and asks other clients to get approval by email. PopMCP connects to BILL's API instead, which you can set up today and which covers creating bills, paying, invoicing, approvals, classifications, webhooks and the rest.

Can the agent move money, or only read?

It can move money if you let it. create_payment, create_bulk_payment and create_mass_payment pay vendors, charge_customer takes money from a customer's bank account, and create_vendor_bank_account changes where money goes. Those tools say so in their descriptions. BILL also requires a code texted to your phone before the first payment, which lasts 30 days. To keep it to reading, choose read-only for the connection in PopMCP.

What stops a payment going out twice?

BILL's API has no duplicate protection for payments, so PopMCP adds some: the same payment sent again within 15 minutes is refused unless the AI marks it as a deliberate second one. You also cannot overpay a bill in BILL. If a call times out, the AI is told to look the payment up before trying again.

Can the AI see card numbers or bank details?

No full card number or security code ever passes through. PopMCP leaves out BILL's card details call, and refuses a card number sent to any tool. Bank account numbers and tax IDs show only their last four digits, and vendor bank details can only be set by a tool that warns about fraud in its description.

How many BILL operations does the connection expose?

309 operations across vendors, bills, payments, approvals, customers, invoices, funding accounts, classifications, the BILL network, webhooks, budgets, cards, transactions and reimbursements, plus seven multi-step tools such as payables_summary and prepare_payment. 40 load into your AI client by default and the rest stay searchable.

Which BILL events can PopMCP watch?

Bills, vendors and invoices being created, changed, archived or restored, payments changing status or failing, vendor auto-pay failing, bank and card accounts being added or changed, and on Spend & Expense, card transactions, reimbursements and purchases needing approval.

Do I have to run or host the Bill.com MCP server myself?

No. PopMCP hosts it and gives you a Streamable HTTP MCP URL. There is nothing to deploy, no callback URL to register, and no infrastructure to keep running or patch.

Which AI clients can use this MCP server?

Any client that supports a remote Streamable HTTP MCP server: Claude Desktop, Claude Web, Claude Code, ChatGPT custom connectors, Codex and the Codex CLI, OpenCode and Z.ai's ZCode, as well as editors such as Cursor, Windsurf and Zed. Your client signs in to PopMCP with OAuth; the provider credential never leaves the server.

How do I connect Bill.com to Claude Code?

Connect Bill.com in PopMCP first, then run claude mcp add --transport http popmcp https://app.popmcp.com/mcp in a terminal. Inside Claude Code, run /mcp and sign in to PopMCP in the browser window it opens, ticking Bill.com on the consent screen. The Bill.com tools are then available in that session, and no Bill.com credential is stored on your machine.

Why do only 40 of the 316 tools load by default?

Loading 316 tool definitions into every conversation burns context before the work starts. PopMCP loads a curated 40-tool set covering the everyday workflows and keeps the rest searchable, so your AI pulls a specialist tool only when a task needs it. Every tool stays searchable, and on Scale the owner can load the full catalog for a teammate's connection.

What is the difference between a tool and a trigger?

A tool is something your AI calls, and there are 316 here. A trigger is something PopMCP watches for you: 26 Bill.com events that can start work on the PopMCP side. Triggers never enter your AI client's context, and none of them ask you to paste a callback URL into Bill.com.
