Keel

Keel is an MCP (Model Context Protocol) server focused on providing a suite of network diagnostic tools to AI assistants such as Claude, Cursor, and Windsurf. It enables AI models to perform common tasks like ping, traceroute, DNS lookups, port scans, SSL certificate checks, and more, exposing these capabilities as structured, validated MCP tool calls. Keel is ideal for AI-powered troubleshooting, remote diagnostics, and network analysis. It integrates with MCP clients and can be incorporated into local and desktop AI workflows. Security features include input validation, SSRF protection, rate limiting, and subnet restrictions.
