# BILL MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to BILL and the rest of your systems. It gives your agent 306 BILL actions (112 reads, 172 writes and 22 that wait for a confirmation) and holds the BILL credential itself, so the agent never does. It paces BILL's limits and records every call.

[Connect BILL free](https://actionlake.com/console?start=sandbox) [See pricing](https://actionlake.com/pricing)

100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you.

the first call

```
do {
  action: "bill.invoices.list",
  intent: "check which BILL account is connected"
}
# Get list of invoices · read · 1 upstream call
```

- 306 actions in one signed file
- 112 read look, never change
- 172 write create and update
- 22 wait for a yes destructive, confirmed first

Set up

## Connect BILL in three steps.

1. 01
   ### Add actionlake to Claude.
   Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.
   `https://connect.actionlake.com/mcp`
2. 02
   ### Connect BILL.
   Session login. actionlake opens the session and renews it when it expires. actionlake stores what you paste write-only, sealed under your tenant's key.
   - `dev_key` BILL developer key (devKey)
   - `username` BILL sign-in email address
   - `password` BILL sign-in password
   - `organization_id` BILL organization ID (begins with 008)
   - `remember_me_id` MFA rememberMeId (optional; from POST /v3/mfa/challenge/validate with rememberMe true, valid 30 days) for an…
   - `device` MFA device nickname used with rememberMeId (optional)
   - `api_token` Spend & Expense API token (optional; needed only for /v3/spend actions)
   - `host` Where your BILL lives: your host
   ```
   account { op: "connections.requirements", service: "bill" }
   # free: exactly what to paste, and what is found for you
   ```
3. 03
   ### Make the first call. Check before a write.
   Ask in plain words; Claude picks the action. Before anything changes, `check` validates the call and prices it, for free.
   ```
   do    { action: "bill.invoices.list" }
   # get list of invoices · read · 1 upstream call
   check { action: "bill.invoices.create", input: { … } }
   # free: inputs, permissions, cost and confirmations, nothing sent
   ```

Top actions

## The BILL API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 65 of BILL's 69 action names are shared with at least one other connector, so an agent learns them once.

| Action | What it does | Effect | Same name in |

Try it

## Prompts to paste into Claude.

Each one names the BILL actions it will call, so you know what it reads and what it changes before you send it.

1. Read read
   Which BILL invoices are more than 30 days overdue? Group them by customer with the total owed.
   calls `bill.invoices.list`
2. Write write
   Create an invoice in BILL. Show me exactly what you will send before you save it.
   calls `bill.invoices.create`
3. Across systems read
   For each customer, how many invoices are in BILL and how many tickets in ConnectWise PSA?
   calls `bill.invoices.list` `connectwise_manage.tickets.list`

Across your systems

## BILL, joined to the rest of your business.

One `ask` fetches from BILL and another system, joins the rows on the same customer on our side, and hands your agent the answer, not every row.

- For each customer, how many invoices are in BILL and how many tickets in ConnectWise PSA?
  `bill.invoices.list` + `connectwise_manage.tickets.list`, on `crm.company` · [ConnectWise PSA](https://actionlake.com/connectors/connectwise-psa)
- For each customer, how many invoices are in BILL and how many tickets in HubSpot CRM?
  `bill.invoices.list` + `hubspot_crm.tickets.list`, on `crm.company` · [HubSpot CRM](https://actionlake.com/connectors/hubspot-crm)

Also mapped by other connectors `identity.user` **517** `crm.company` **227** `finance.invoice` **91** `finance.payment` **53** `commerce.customer` **51** `asset.supplier` **38** `finance.ledger_account` **32** `finance.credit_note` **28**

ask

```
ask {
  intent: "for each customer, how many invoices are in BILL and how many tickets in ConnectWise PSA",
  steps: [
    { action: "bill.invoices.list", as: "inv", input: {}, limit: 100, max_pages: 5 },
    { action: "connectwise_manage.tickets.list", as: "tix", input: {}, limit: 100, max_pages: 5 },
    { join: {
        left: "inv",
        right: "tix",
        on: "crm.company",
        group_by: "inv.company_name",
        select: ["inv.company_name", "count(inv.id) as invoices", "count(tix.id) as tickets"]
    } }
  ]
}
```

Example. Run it through check first: it validates the steps and prices them, and it is free.

Governance for BILL

## Destructive actions wait for a yes.

22 BILL actions are destructive. These are all of them:

- Delete a reimbursement `bill.spend_reimbursements.delete`
- Void a payment `bill.payments.void`
- Cancel a payment `bill.payments.cancel`
- Delete a budget `bill.spend_budgets.delete`
- Create a payment `bill.payments.create`
- Delete a vendor card `bill.spend_cards.delete`
- Delete a user `bill.spend_users.delete`
- Create a bulk payment `bill.payments.bulk_create`
- Create a mass payment `bill.payments_mass.create`
- Charge a customer `bill.receivable_payments.charge`
- Set charge customer authorization `bill.customers.charge_authorization`
- Delete an attachment `bill.attachments.delete`
- Delete a custom field `bill.spend_custom_fields.delete`
- Delete a vendor bank account `bill.vendors_bank_account.delete`
- Delete a budget member `bill.spend_budgets_members.delete`
- Delete a subscription `bill.webhook_subscriptions.delete`
- Delete a bill approval policy `bill.bill_approvals_policies.delete`
- Delete vendor connection `bill.network_invitation_vendor.delete`
- Delete a custom field value `bill.spend_custom_fields_values.delete`
- Delete customer connection `bill.network_invitation_customer.delete`
- Delete a transaction receipt `bill.spend_transactions_receipts.delete`
- Delete a reimbursement receipt `bill.spend_reimbursements_receipts.delete`

A destructive action runs only with `confirm: true`. Under the `human` policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

do bill.spend_reimbursements.delete confirm_policy: **human**

Delete a reimbursement?

**intent:** the user asked me to delete a reimbursement

run suspended · waiting for a named person · key _bill-agent_ cannot confirm itself

In the console, or from an emailed signed link.

```
account {
  op: "keys.create", name: "bill-agent",

    { match: "bill.payments.void", approver: "lead@example.com" },
    { match: "bill.payments.cancel", approver: "lead@example.com" }

Illustrative. Scoped to BILL only, capped at 2,000 upstream calls, every write confirmed, and the destructive ones approved by a named person.

Questions

## The BILL MCP server, answered.

**Is there a BILL MCP server for Claude?**

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 306 BILL actions across credit memos, accounting classes, chart of accounts and departments, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by BILL.

**What do I need to connect BILL?**

BILL developer key (devKey), BILL sign-in email address, BILL sign-in password, BILL organization ID (begins with 008), MFA rememberMeId (optional; from POST /v3/mfa/challenge/validate with rememberMe true, valid 30 days) for an…, MFA device nickname used with rememberMeId (optional) and Spend & Expense API token (optional; needed only for /v3/spend actions). Plus your host. The free call account { op: "connections.requirements", service: "bill" } lists exactly what to paste.

**Can an AI agent delete or change things in BILL?**

Only if its key allows it, and only with an explicit confirmation. 22 BILL actions are destructive, including delete a reimbursement, void a payment and cancel a payment. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

**Will an AI agent use up my BILL API limit?**

actionlake paces every call to the limits in the BILL service file: 20,000 calls an hour and 3 a second per connection. Repeated reads are answered from cache (101 BILL actions can be), which never reaches BILL.

**What does a BILL action cost?**

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (306 BILL actions page). Cache hits, searches, dry runs and calls BILL refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

**Which BILL API does it cover?**

The BILL v3 API (OpenAPI 3.0.1, per-operation definitions from developer.bill.com) at gateway.prod.bill.com by default, or the base URL set when you connect. It is built from BILL's documentation as read on 22 October 2026. 306 actions in 87 areas, each one in the signed service file (version 1.0.0).

**Can I combine BILL with my other systems?**

Yes. ask joins BILL to ConnectWise PSA or HubSpot CRM on the same customer and returns the answer rather than every row. BILL maps crm.company, which 227 other connectors also map.

**Does actionlake keep my BILL data, and where?**

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your BILL credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

**Which AI clients can use it?**

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
