What the code does

We read the source, 23 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.

Dumps the whole environment apps/web-next/vite.config.ts:18
    __APP_VERSION__: JSON.stringify(process.env.npm_package_version ?? "0.0.0-dev"),
Touches key and credential files docker/deploy-cloud.sh:39
: "${SSH_KEY:?CLOUD_SSH_KEY is unset. Add it to docker/.env.cloud, e.g. ~/.ssh/your_key}"
  <script src="https://challenges.cloudflare.com/turnstile/v0/api.js" async defer></script>
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/sdk-gen.yml:28
      - name: Notify Stainless of spec update
        if: env.HAS_KEY == 'true'
        env:
          GITHUB_SHA_REF: ${{ github.sha }}

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.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add mcp -- npx -y @gatewerk/mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "mcp": {
      "args": [
        "-y",
        "@gatewerk/mcp"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.mcp]
command = "npx"
args = ["-y", "@gatewerk/mcp"]
.cursor/mcp.json
{
  "mcpServers": {
    "mcp": {
      "args": [
        "-y",
        "@gatewerk/mcp"
      ],
      "command": "npx"
    }
  }
}
.vscode/mcp.json

        "@gatewerk/mcp"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: GATEWERK_API_KEY (Gatewerk API key (gwk_...). Generate one at your Gatewerk instance under Settings → API Keys.), GATEWERK_URL (Base URL of your self-hosted Gatewerk instance (e.g. https://api.gatewerk.com). Defaults to http://localhost:3100.), GATEWERK_REVIEWER (Reviewer email used as decision attribution. When set, decisions made through the MCP server are attributed to this reviewer instead of the API key identity.). The author declared them in the registry entry; get the values from the project itself.

Gatewerk — questions

Answers built from our own checks of this server.

Why is there no uptime for Gatewerk?
Gatewerk 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 @gatewerk/mcp was installed 32 times last week.
How do I connect Gatewerk?
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 @gatewerk/mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Gatewerk?
The npm package @gatewerk/mcp was installed 32 times in the last week. Week over week that is +48%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Gatewerk open source?
Yes — it is published under the AGPL-3.0 licence, written in TypeScript 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.
