VerifiedSTDIODesktop onlyBusiness & Commerce

Overview

AI-generated overview

Validates Polish KSeF structured invoice XML and flags the lines that would be rejected before submission.

What you can do
This local MCP server checks Polish structured invoice XML against KSeF requirements and reports the lines that would be rejected, so problems can be fixed before the file is sent. The registry description states it finds the lines KSeF will reject in a Polish structured invoice XML before you send it. No individual tools are listed in the supplied manifest.
When to use it
Useful when preparing or reviewing Polish structured invoice XML for KSeF submission and you want an assistant to point out lines likely to be rejected before sending. It is a pre-submission check rather than a general invoicing or accounting tool.
Requirements
Runs as a local process on the user's machine over stdio, started with npx from the npm package @readystack/ksef-fa3-invoice-lint. Desktop only; no web executable. No authentication, environment variables or headers are declared.
Before you install
The supplied manifest declares no credentials, no environment variables and no headers, and the description only mentions checking XML. The README content does not describe this server's usage, so verify what it does before relying on it.

Score

40% of the applicable checks met

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.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
