Invoice

Overview

Invoice is a Model Context Protocol (MCP) server: Check invoice mandatory fields, validate a draft before issuing, and look up EN 16931 code lists. Because it speaks the Model Context Protocol, AI assistants can use Invoice as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the npm package yaktool-invoice-mcp speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.2.0.

On mcp.site, Invoice sits in the Finance category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
