Gofact MCP Server

Small Go binary that turns a print-ready HTML invoice into Factur-X: a compliant PDF/A-3 with the CII EN 16931 XML embedded, and optionally submits it to a French e-invoicing platform (PDP - plateforme de dématérialisation partenaire).

People who work with e invoicing, en16931 and factur x and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Go.
