Scribo

causa-prima-ai/scribo-mcp

A hosted MCP server that generates EN 16931-compliant invoices from plain language. Point your client at the remote URL and you get four tools: create_invoice builds ZUGFeRD, XRechnung, or US PDF invoices from sender and recipient details, verify_email_code confirms ownership with a six-digit code on first use, get_invoice refetches past invoices, and list_supported_jurisdictions shows available formats. Germany B2B and B2G plus US plain PDF are live; France, Spain, and Peppol BIS are coming. Output is validated against the Invopop rule set before it reaches you. No signup, no auth, free forever. Reach for this when you need compliant European e-invoices without standing up your own infrastructure or parsing XML schemas.

What is Scribo?

Scribo is a free, conversational e-invoicing tool. Describe an invoice in plain language — "bill Acme GmbH €2,400 for May design work" — and it drafts a structured invoice for you to review, download and send directly.

Just ask your AI agent about Scribo: it ships as an MCP server, a CLI, and a Claude/Codex skill, alongside a public HTTP API and a web app. Free forever — no credit card. You just need a sender email.
