What the code does

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 npm/run.js:82
    execFileSync(binPath, args, { stdio: "inherit" });
Builds a file path from a variable capabilities/google/gmail_save_attachment.yaml:59
        save_path = os.path.join(out_dir, filename)
Page executes code built at runtime src/gateway/ui/index.html:798
  document.getElementById('cp-mode').innerHTML = route.read_only
Touches key and credential files src/validator/rules/tool_poisoning.rs:84
    ("id_rsa", HighCategory::FilesystemPath),
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:204
        run: sudo apt-get update && sudo apt-get install -y ${{ matrix.packages }}

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.

MCP Gateway — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Gateway?
MCP Gateway runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.
Is MCP Gateway open source?
We cannot say either way: written in Rust, 72 stars on GitHub and 24 open issues, but we could not determine the licence, and without one the code is not open source by default.
