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.

File ships in the package but is absent from the source [пакет] public/dashboard.html:1, [пакет] src/cli.mjs:1, [пакет] src/detect.mjs:1 и ещё 5
этот файл ставится пользователю, но в репозитории его нет
  try { spawn(cmd, args, { stdio: 'ignore', detached: true }).unref(); } catch { /* the URL is printed anyway */ }

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 file path from a variable .github/workflows/ci.yml:41
              const root = path.join(m.metadata?.pluginRoot || ".", p.source);

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

    }
  }
}

This one needs environment variables set before it will start: GOVERNOR_PORT (Port where GVNR is running (npx enforcer-governor start). Defaults to 4000.), GVNR_AGENT (A name for this client's agent, shown as mcp:<name>. Defaults to a random id per session.). The author declared them in the registry entry; get the values from the project itself.

GVNR by Instruxi — questions

Answers built from our own checks of this server.

Why is there no uptime for GVNR by Instruxi?
GVNR by Instruxi 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 enforcer-governor.
How do I connect GVNR by Instruxi?
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 enforcer-governor straight from npm; nothing to host, nothing to sign up for.
Is GVNR by Instruxi open source?
No, and the distinction matters: its licence is declared as FSL-1.1-ALv2. That makes it source-available — you can read the code, but the terms are the author's own, not one of the recognised open-source licences. Read them before you build on it.
