Overview

Connect your own Billomat account to Claude and automate billing workflows via AI. The server is multi-tenant — every user connects with their own credentials, so your data stays private.

Setup (Required)

You need a Billomat account (free trial works). Follow these 3 steps:

Step 1: Enable API Access in Billomat

In Billomat: Settings → Users → "edit" → API Access → check "activate?" ✓ → Save

Then click "Show API Key" and copy your key.

Note: API access is disabled by default in Billomat. You must enable it before the key will work.

Step 2: Find your credentials

Value	Where to find it	Example
Subdomain	Your Billomat URL: [subdomain].billomat.net	mycompany
API Key	Billomat → Settings → Users → edit → Show API Key	abc123...

Step 3: Configure your MCP client

When adding this server, set these request headers:

X-Billomat-Api-Key: your-api-key X-Billomat-Subdomain: your-subdomain

Available Tools (14)

Clients: list-clients, get-client, create-client, update-client

Invoices: list-invoices, get-invoice, create-invoice, update-invoice, complete-invoice, send-invoice-email

Example

"Create an invoice for Max Muster for 5 hours consulting at €150/h, 19% VAT, due in 14 days."

The AI automatically calls list-clients → create-invoice → complete-invoice → send-invoice-email.
