Yaktool

Overview

Yaktool is a Model Context Protocol (MCP) server: 73 local deterministic tools: GTIN, feeds, CSV-XLSX, Digital Link QR, e-invoices. Rules cited. In practice that means any MCP-compatible AI assistant can call Yaktool's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package yaktool-mcp speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.4.2.

Yaktool is listed under Finance on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
