NodeJS LTS is supported

🛠️ Built on NodeJs version

v24.14.1

📝 Description

A Model Context Protocol (MCP) server that exposes the network.corifeus.com diagnostics suite — DNS, SSL, WHOIS, email deliverability, BGP, security headers, and more — directly inside any MCP-compatible AI assistant (Claude Code, Codex, Cursor, and others).

Ask in plain language: "audit example.com", "why do my emails land in spam?", "check DNS propagation for patrikx3.com" — and the assistant calls the right tool for you.

Features

• 17 tools — audits, DNS, SSL, WHOIS, HTTP, email deliverability, blacklist lookups, BGP, geolocation, IPv6
• Zero config — runs over stdio with npx, no account, no API key
• AI-powered audit — network_audit returns a single combined health report
• Live email test — end-to-end SPF/DKIM/DMARC verification with spam score and AI-generated fix suggestions
• Works with every MCP client — Claude Code, Codex, Cursor, Continue, or any custom host

Install

Claude Code

claude mcp add p3x-network -- npx p3x-network-mcp

Or with a global install:

npm install -g p3x-network-mcp
claude mcp add p3x-network -- p3x-network-mcp

Codex

Add to your MCP config (~/.codex/config.json or project-level):

{
  "mcpServers": {
    "p3x-network": {
      "command": "npx",
      "args": ["p3x-network-mcp"]
    }
  }
}

Generic MCP client

Any MCP-compatible client can use this server via stdio transport:

npx p3x-network-mcp

Available Tools

| Tool | Description | |------|-------------| | network_audit | AI-powered comprehensive network analysis | | dns_lookup | Query DNS records (A, AAAA, CNAME, NS, MX, TXT, SOA) | | ssl_check | SSL/TLS certificate details | | whois | WHOIS lookup for domains and IPs | | security_headers | HTTP security headers analysis (HSTS, CSP, etc.) | | mx_check | MX record and mail server check | | email_deliverability | SPF, DKIM, DMARC validation | | dnsbl | DNS blacklist check for IPs | | bgp | BGP routing info by prefix or ASN | | reverse_dns | PTR record lookup | | http_check | HTTP response, redirects, status codes | | dns_propagation | Global DNS propagation check | | ipv6_check | IPv6 support verification | | geolocation | IP geolocation data | | my_ip | Server public IP address | | email_test | Start a live email deliverability test (SPF, DKIM, DMARC, spam score, AI analysis). Results are sent by email automatically. | | email_test_result | Get the result of a previously started email test (optional — results are also emailed) |

Usage Examples

"audit example.com"
"check DNS for cloudflare.com"
"is patrikx3.com secure?"
"whois google.com"
"check email deliverability for example.com"
"test email [email protected]"

Email Test Flow

The email_test tool performs a live end-to-end email deliverability test:

1. Call email_test with an email address (e.g. [email protected]) and optional language code
2. The system sends a test email to that address
3. The recipient replies to the test email
4. Results are automatically sent by email — no polling required! The result email includes:
   • Score (0-10)
   • SPF, DKIM, DMARC authentication results
   • Individual blacklist status for all 23 checked lists
   • Spam score
   • Message format and header analysis
   • AI-powered recommendations in the selected language
5. Optionally, call email_test_result with the returned testId to get results programmatically

Supported languages: en, hu, de, fr, es, it, cs, ru, zh, ja

This goes beyond passive DNS checks (email_deliverability) by verifying that email authentication actually works in practice on a real delivered message.
