Kema Invoice MCP connector
Kema Invoice is compliant e-invoicing software that AI agents can operate through the Model Context Protocol. Connect the remote MCP server to Claude, Cursor or any MCP client, authorize once with OAuth 2.1, and your agent can create, issue, send and track invoices, quotes and retainers in plain language. Invoices are generated as Factur-X (EN 16931) and transmitted through an accredited platform. Nothing to install: the server runs at https://mcp.kema-studio.com/api/mcp.

What this repository is
The connector is a remote MCP server (Streamable HTTP + OAuth 2.1). There is no package to install and the server code is not published here. This repository holds what an integrator or a directory needs:
Connect in two minutes
The first call opens a consent page on auth.kema-studio.com. You sign in with your Kema Invoice account, approve, and the client stores the token. Access can be revoked at any time from the app or from the client.
No account yet? Create one: 14-day trial with 10 invoices included, one user, no credit card. Then a single plan at €10 per user per month excl. VAT, every feature included, cancel at any time.

Design rules the server follows: one title per tool, readOnlyHint on reads and an explicit destructiveHint on writes, a description on every parameter, an outputSchema and structuredContent on every result. Tool names are frozen: your prompts and automations keep working across versions.
A refused call (no active subscription, quota reached) is returned as a tool result written for the model, not as a transport error: the connector stays connected and keeps listing its tools.
Try it
Ask your agent, in your language:
- "Invoice 3 days of consulting to Dupont SARL at €800 per day."
- "List my unpaid invoices and mark FAC-2026-0412 as paid."
- "Turn quote DEV-2026-0031 into an invoice and send it."
More in examples/prompts.md.
Compliance and data
- Invoices are produced as Factur-X (PDF/A-3 with embedded EN 16931 XML) and transmitted through an accredited platform, ready for the French e-invoicing mandate.
- Data is hosted in the European Union (database and authentication on AWS eu-north-1, Stockholm; edge and storage in the EU). Sub-processors and retention periods are listed in the privacy policy.
- Every MCP call is logged in the app under Agent activity, so you always see what your agent did.
