Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.

Remote servers are capped at 8.0 because source code is not available for review. The score reflects endpoint verification only.

DetectZeStack MCP Server

An MCP (Model Context Protocol) server that lets AI agents detect technology stacks, analyze security headers, inspect SSL certificates, look up DNS records, and scan for vulnerabilities on any website.

Quick Start

Claude Code

Add to .mcp.json in your project root (or ~/.claude/.mcp.json for global):

{
  "mcpServers": {
    "detectzestack": {
      "command": "npx",
      "args": ["-y", "detectzestack-mcp"],
      "env": {
        "RAPIDAPI_KEY": "your-rapidapi-key"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "detectzestack": {
      "command": "npx",
      "args": ["-y", "detectzestack-mcp"],
      "env": {
        "RAPIDAPI_KEY": "your-rapidapi-key"
      }
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "detectzestack": {
      "command": "npx",
      "args": ["-y", "detectzestack-mcp"],
      "env": {
        "RAPIDAPI_KEY": "your-rapidapi-key"
      }
    }
  }
}

Get Your API Key

Either:

Direct: sign up at detectzestack.com/signup (free tier: 100 requests/month) and set DETECTZESTACK_API_KEY, or
RapidAPI: subscribe at DetectZeStack on RapidAPI and set RAPIDAPI_KEY.

Alternative API Providers

Instead of RapidAPI, you can use API.market or a direct API key:

API.market:

{
  "mcpServers": {
    "detectzestack": {
      "command": "npx",
      "args": ["-y", "detectzestack-mcp"],
      "env": {
        "APIMARKET_KEY": "your-apimarket-key"
      }
    }
  }
}

Direct API Key:

{
  "mcpServers": {
    "detectzestack": {
      "command": "npx",
      "args": ["-y", "detectzestack-mcp"],
      "env": {
        "DETECTZESTACK_API_KEY": "your-api-key"
      }
    }
  }
}

Provider priority: RAPIDAPI_KEY > APIMARKET_KEY > DETECTZESTACK_API_KEY
