What the code does

We read the source, 2 d ago · rules ccca72095570

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

Nothing serious here today

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

mcp-audit — questions

Answers built from our own checks of this server.

Why is there no uptime for mcp-audit?
mcp-audit 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 mcp-audit-proxy was installed 28 times last week.
How do I connect mcp-audit?
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 mcp-audit-proxy straight from npm; nothing to host, nothing to sign up for.
How many people use mcp-audit?
The npm package mcp-audit-proxy was installed 28 times in the last week. Week over week that is +0%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is mcp-audit open source?
Yes — it is published under the Apache-2.0 licence, written in Go and 2 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
