What the code does

We read the source, 2 d ago · rules ccca72095570

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.

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.

File ships in the package but is absent from the source [пакет] bin/husk.cjs:1
этот файл ставится пользователю, но в репозитории его нет
  const result = spawnSync(process.execPath, ["--check", shim], { stdio: "pipe" });
Builds a file path from a variable npm/build.mjs:68
  const source = path.join(binaries, target.rustTarget, binFile);
        ("npm config", home.join(".npmrc")),
Asks for container control access src/scan/checks/container.rs:26
            "A process with /var/run/docker.sock can ask the daemon for a privileged container, which is root on the host.",

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.

Builds a database query by concatenation .github/workflows/release.yml:109
          sudo apt-get update
          sudo apt-get install -y ${{ matrix.apt }}

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 Husk and you get told the day something new turns up.

Husk — questions

Answers built from our own checks of this server.

Why is there no uptime for Husk?
Husk 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 husk-sec was installed 37 times last week.
How do I connect Husk?
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 husk-sec straight from npm; nothing to host, nothing to sign up for.
How many people use Husk?
The npm package husk-sec was installed 37 times in the last week. Week over week that is +39%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Husk open source?
Yes — it is published under the MIT licence, written in Rust and 6 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.
