How to connect Tool Poisoning Scanner

Tool Poisoning Scanner runs locally from a Node.js package published to the npm registry: @guardbee/mcp-tool-poisoning-scanner 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-tool-poisoning-scanner@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": {
    "tool-poisoning-scanner": {
      "command": "npx",
      "args": [
        "-y",
        "@guardbee/mcp-tool-poisoning-scanner@0.2.1"
      ]
    }
  }
}
