Overview

AI-generated overview

Yaktool is a local MCP server offering 73 deterministic tools for GTIN, product feeds, CSV/XLSX conversion, Digital Link QR codes and e-invoices.

What you can do
  • Work with GTIN identifiers and product data feeds
  • Convert between CSV and XLSX files
  • Generate Digital Link QR codes
  • Handle e-invoice data
  • Runs entirely locally with deterministic, rules-cited outputs
When to use it
Useful when an assistant needs to validate or transform product and commerce data files, such as GTIN checks, feed preparation, spreadsheet conversion or e-invoice handling, and you want the work done locally without external services.
Requirements
Runs as a local stdio process installed from the npm package yaktool-mcp, so a Node.js runtime is needed. No authentication, environment variables or headers are declared. Desktop only; not available as a web executable.
Before you install
The tool list is not published in the manifest, so review the exact tools after installing. It processes product, feed and invoice data locally; confirm how files are read and written before pointing it at sensitive business data.

Installation

In SourceWeft

  1. Open Yaktool in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
