MCP Ksef Pl — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Ksef Pl?

MCP Ksef Pl runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package mcp-ksef-pl was installed 267 times last week.

How do I connect MCP Ksef Pl?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls mcp-ksef-pl straight from pypi; nothing to host, nothing to sign up for.

How many people use MCP Ksef Pl?

The pypi package mcp-ksef-pl was installed 267 times in the last week. Week over week that is +93%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is MCP Ksef Pl open source?

Yes — it is published under the Apache-2.0 licence, written in Python, 3 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
