PrufGate MCP Server

by guardianvigil-labs Your server? Claim it
local only

PrufGate runs on your own machine — the client starts it, so there is no endpoint to ping. 1 324 installs a week from pypi. Last commit 27 Oct 2026.

Read-only tools that check whether code, and the tests that claim it works, are real.

What the code does

We read the source, 4 d ago · rules 995398eba69f

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

  execFile(program, args, { cwd: folder.uri.fsPath, timeout: TIMEOUT_MS, maxBuffer: MAX_OUTPUT, env: childEnv(), windowsHide: true },
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.

Builds a file path from a variable editors/vscode/src/cli.ts:18
      const candidate = path.join(dir, name + ext);
Runs an external command editors/vscode/src/extension.ts:56
  execFile(program, args, { cwd: folder.uri.fsPath, timeout: TIMEOUT_MS, maxBuffer: MAX_OUTPUT, env: childEnv(), windowsHide: true },
        doc = yaml.load(text, Loader=_NoAliasLoader)  # noqa: S506 (a SafeLoader)

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

We found things in this code

Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch PrufGate and you get told the day something new turns up.

PrufGate — questions

Answers built from our own checks of this server.

Why is there no uptime for PrufGate?
PrufGate 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 pypi package prufgate was installed 1 324 times last week.
How do I connect PrufGate?
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 prufgate straight from pypi; nothing to host, nothing to sign up for.
How many people use PrufGate?
The pypi package prufgate was installed 1 324 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 PrufGate open source?
Yes — it is published under the Apache-2.0 licence, written in Python and 1 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.
