How to connect Rug Pull Detector

Rug Pull Detector runs locally from a Node.js package published to the npm registry: @guardbee/mcp-rug-pull-detector version 0.2.1. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y @guardbee/mcp-rug-pull-detector@0.2.1.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "rug-pull-detector": {
      "command": "npx",
      "args": [
        "-y",
        "@guardbee/mcp-rug-pull-detector@0.2.1"
      ]
    }
  }
}
