Nothing serious here today

Today is the operative word: we check Lexware every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Lexware — questions

Answers built from our own checks of this server.

Why is there no uptime for Lexware?

Lexware 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 npm package @lazyants/lexware-mcp-server was installed 1 483 times last week.

How do I connect Lexware?

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 @lazyants/lexware-mcp-server straight from npm; nothing to host, nothing to sign up for.

How many people use Lexware?

The npm package @lazyants/lexware-mcp-server was installed 1 483 times in the last week. Week over week that is +1157%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Lexware open source?

No, and the distinction matters: its licence is declared as FSL-1.1-MIT. That makes it source-available — you can read the code, but the terms are the author's own, not one of the recognised open-source licences. Read them before you build on it.
