What the code does

We read the source, 17 h ago · rules 3dff92dd89df

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command action/index.mjs:33
  return execFileSync(cmd, args, { encoding: "utf8", ...opts });

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

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Confdiff MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Confdiff MCP?
Confdiff MCP 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 confdiff-mcp was installed 175 times last week.
How do I connect Confdiff MCP?
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 confdiff-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Confdiff MCP?
The npm package confdiff-mcp was installed 175 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.
Is Confdiff MCP open source?
Yes — it is published under the MIT licence, written in JavaScript and 39 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.
