Check MCP Server

check-mcp

MCP server for Check — validate any command before execution.

AI agents don't know if their own commands will work. Check does. $0.04 per check.

Install

npm install -g @golproductions/check-mcp

Or run directly:

npx @golproductions/check-mcp

Setup

Add to your MCP config (Claude Code, Cursor, etc.):

{
  "mcpServers": {
    "check": {
      "command": "npx",
      "args": ["@golproductions/check-mcp"],
      "env": {
        "GOL_CLIENT_ID": "your_client_id"
      }
    }
  }
}

What it does

One tool: check

The agent calls check before executing any shell command. It returns:

• RUNNABLE — the command will work, execute it
• INVALID — the command will fail or is unsafe, with a reason

Why

Every wrong command an AI agent runs triggers a retry loop. Every retry is an inference call you're paying for. Check breaks the loop at step 1.

Pricing

$0.04 AUD per check.
