Configuration

Get a free API key at rubiscout.com/dashboard, then add to your MCP client config (e.g. ~/.claude/settings.json or Claude Desktop config):

{
  "mcpServers": {
    "rubiscout": {
      "command": "npx",
      "args": ["-y", "rubiscout-mcp"],
      "env": {
        "RUBISCOUT_API_KEY": "rbs_live_..."
      }
    }
  }
}

Alternatively, set RUBISCOUT_API_KEY as a system environment variable and omit the env block.
