Irs Taxpayer — questions

Answers built from our own checks of this server.

Why is there no uptime for Irs Taxpayer?

Irs Taxpayer 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 irs-taxpayer-mcp was installed 281 times last week.

How do I connect Irs Taxpayer?

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 irs-taxpayer-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Irs Taxpayer?

The npm package irs-taxpayer-mcp was installed 281 times in the last week. Week over week that is -40%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Irs Taxpayer open source?

Yes — it is published under the MIT licence, written in TypeScript, 13 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.
