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

Invoice — questions

Answers built from our own checks of this server.

Why is there no uptime for Invoice?

Invoice 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 yaktool-invoice-mcp was installed 341 times last week.

How do I connect Invoice?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls yaktool-invoice-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Invoice?

The npm package yaktool-invoice-mcp was installed 341 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
