Tallystick

A local MCP server that lets an assistant read, validate and write European e-invoices such as XRechnung, ZUGFeRD, Factur-X, UBL and CII on the user's own маши.

What you can do

Read e-invoice files in the supported formats and extract their contents for the assistant to work with. Validate e-invoices against the format rules. Write or generate e-invoice documents. The manifest lists six tools but does not name them, so the exact split between reading, validating and writing is not documented.

When to use it

Useful when you work with European e-invoicing formats and want an assistant to inspect, check or produce invoice files locally without uploading them to a hosted service.

Requirements

Runs as a local process on the user's desktop machine, installed from the PyPI package tallystick-mcp over stdio. Requires a licence key supplied in the TALLYSTICK_LICENSE_KEY environment variable; all six tools need it. Optionally set TALLYSTICK_TEMPLATES to a folder of invoice2data YAML templates for supplier-specific PDF layouts.
