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.

    if !std::path::Path::new("/.dockerenv").exists() {

    return subprocess.run(args, **kw)

    const filePath = path.join(config.uploadDir, filename);

      - /var/run/docker.sock:/var/run/docker.sock:ro

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 gctrl -- npx -y gctrl-mcp

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

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

{
  "mcpServers": {
    "gctrl": {
      "args": [
        "-y",
        "gctrl-mcp"

This one needs environment variables set before it will start: GCTRL_GATEWAY_URL (URL of your GCTRL harness MCP gateway, e.g. http://localhost:4000/api/agent/mcp (recommended mode)), GCTRL_API_URL (Direct GCTRL API base URL (alternative to gateway mode), e.g. http://localhost:4000/api), GCTRL_API_TOKEN (Scoped GCTRL Access Token (gctrl_…) created in Settings → Access Control). The author declared them in the registry entry; get the values from the project itself.
