What the code does

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.

  "If the listing cannot explain whether the hosted server can reach 169.254.169.254, loopback, RFC1918 ranges, IPv6 local addresses, or Kubernetes service names, keep it in review instead of the agent-visible candidate set.",

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.

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.

claude mcp add rhumb-mcp -- npx -y rhumb-mcp

{
  "mcpServers": {
    "rhumb-mcp": {
      "args": [
        "-y",
        "rhumb-mcp"
      ],
      "command": "npx"
    }
  }
}

[mcp_servers.rhumb-mcp]
command = "npx"
args = ["-y", "rhumb-mcp"]

{
  "mcpServers": {
    "rhumb-mcp": {
      "args": [
        "-y",
        "rhumb-mcp"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: RHUMB_API_KEY (Governed API key for authenticated repeat traffic on X-Rhumb-Key (optional — discovery works without auth; execution otherwise needs x402 payment)). The author declared them in the registry entry; get the values from the project itself.
