## Tools

10 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `find_customers` — Lists customers, optionally filtered by a search text that matches company, names and email.
- `create_customer` — Creates a customer. Needs a company or a last name and a full address (line 1, postal code, city, country).
- `update_customer` — Changes the given fields of a customer; fields that are left out stay as they are.
- `create_invoice` — Creates a draft invoice for a customer. Number, language, texts and VAT treatment come from the account settings.
- `update_invoice` — Changes a draft invoice. Passing items replaces all existing items, so send the complete list. Sent invoices cannot be changed.
- `list_invoices` — Lists invoices, newest first. Status: draft, open (sent and unpaid), overdue (open and past due) or paid.
- `get_invoice` — Returns one invoice with its items, amounts and payment status.
- `download_invoice` — Saves the PDF or the XML e-invoice of an invoice on this computer and returns the file path.
- `record_payment` — Records a payment for one or more sent, open invoices of the same customer and tax rate. The amount is gross.
- `list_payments` — Lists recorded payments, newest first, optionally only those for one invoice.

## Install

**Verdict: review** — Installable, but 1 thing to check first: No publisher has proved control of this listing; it is indexed, not vouched for.
**Cautions** (coverage gaps and advisories — never blocking)
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"billingengine\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"billingengine-mcp\"\n      ],\n      \"env\": {\n        \"BILLINGENGINE_API_KEY\": \"<YOUR_BILLINGENGINE_API_KEY>\"\n      }\n    }\n  }\n}"
```
**Credentials it will ask for** (names only — Forge never holds a value):
- `BILLINGENGINE_API_KEY` — Billingengine API Key (required)
Placeholders only. Forge never holds, brokers, or transmits a credential value — replace each <YOUR_NAME> in your own config file. Do not send a value back to Forge; no Forge endpoint accepts one.
- This entry needs 1 credential (1 required). The generated config carries placeholders, so it will fail in the editor rather than at runtime if they are left unset.

## Blast radius

Moderate blast radius — holds an api key; runs on your machine.
- Floor 23, ceiling 23 (tier: moderate)
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
