Free 🔍 P3X Network MCP is an AI-powered network analysis Model Context Protocol server — published as the npm package p3x-network-mcp — that brings the entire P3X Network toolkit directly into any MCP-compatible AI assistant such as Claude Code, Codex, Cursor, or any other client speaking the protocol. It exposes 17 professional-grade tools including comprehensive network audits, DNS lookup with global propagation tracking, SSL/TLS certificate validation, WHOIS queries, security header analysis (HSTS, CSP, and more), BGP routing inspection by prefix or ASN, MX record and email deliverability testing, DNSBL blacklist checks across 23 lists, IPv6 compatibility verification, HTTP response and redirect inspection, IP geolocation, reverse DNS resolution, and live end-to-end email deliverability testing with SPF/DKIM/DMARC validation, spam scoring, header analysis, and AI-powered remediation recommendations in 10 languages. Install with a single command — claude mcp add p3x-network -- npx p3x-network-mcp — then ask your AI assistant in plain language: "audit example.com," "check email deliverability for my domain," or "why do my emails land in spam?" Released under the MIT license, completely free with no signup required.
