CISA Vulnerability Checker MCP Server

A Model Control Protocol (MCP) server that provides access to CISA's Known Exploited Vulnerabilities (KEV) catalog through Claude and Cursor integration.

MCP Server Functionality

The MCP server provides real-time access to CISA's KEV catalog through Claude and Cursor integration. It enables:

• Real-time CVE checking and monitoring
• Integration with Claude for enhanced security analysis
• Access to the complete CISA KEV catalog

Production Deployment

The MCP server is available at: https://amcipi.com/cisa-kev/

To configure Claude to use the CISA vulnerability checker server, add the following to your Claude configuration file (usually located at ~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "cisa": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://amcipi.com/cisa-kev/mcp"
      ]
    }
  }
}
