What the code does

We read the source, 20 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 demo.py:63
    up = subprocess.Popen([sys.executable, "-m", "tests.fake_upstream"], env=env)

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-airlock -- uvx mcp-airlock
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "mcp-airlock": {
      "args": [
        "mcp-airlock"
      ],
      "command": "uvx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.mcp-airlock]
command = "uvx"
args = ["mcp-airlock"]
.cursor/mcp.json
{
  "mcpServers": {
    "mcp-airlock": {
      "args": [
        "mcp-airlock"
      ],
      "command": "uvx"
    }
  }
}

      "command": "uvx"
    }
  }
}

This one needs environment variables set before it will start: AIRLOCK_JWT_SECRET (HS256 secret for verifying bearer tokens (or set AIRLOCK_JWKS_URL for OIDC)), AIRLOCK_SECRET (Key for signing confirmation tokens; set it when running more than one replica). The author declared them in the registry entry; get the values from the project itself.

mcp-airlock — questions

Answers built from our own checks of this server.

Why is there no uptime for mcp-airlock?
mcp-airlock 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 mcp-airlock.
How do I connect mcp-airlock?
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 mcp-airlock straight from pypi; nothing to host, nothing to sign up for.
Is mcp-airlock open source?
Yes — it is published under the MIT licence, written in Python, 25 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
