MCP Server for AI Agents
Give your coding agent access to things LLMs can't do on their own: make HTTP requests, check DNS records, verify SSL certs, compute cryptographic hashes, execute regex patterns, and generate secure random values.

24 tools total. 13 free (MIT license), 11 Pro ($4.99/month). Works with Claude Desktop, Claude Code, Cursor, and any MCP-compatible agent. New to MCP?
Network things LLMs literally cannot do
| http_request | Make GET/POST/PUT/DELETE requests, see status + headers + body |
| dns_lookup | Resolve A, AAAA, MX, TXT, NS, SOA, or all records for a domain |
| ssl_check | Check certificate issuer, expiry, fingerprint for any domain |
Crypto & random LLMs get these wrong
| hash | MD5, SHA-1, SHA-256, SHA-512 |
| hmac | HMAC signatures (verify GitHub/Stripe webhooks) |
| uuid | Generate v4 UUIDs (single or batch) |
| random_bytes | Cryptographically secure random bytes (hex, base64, base64url) |
| password | Secure password generation with entropy calculation |
Regex LLMs guess; this executes
| regex_test | Run a pattern, get real match positions, groups, named captures |
Encoding & tokens
| jwt_decode | Decode header + payload, check expiration |
| base64 | Encode/decode, with base64url support |
| url_encode | URL encode/decode (component or full URI) |
Format & time
| epoch | Convert timestamps, get current time |
Pro Tools — 11 tools $4.99/month

| bulk_dns | Resolve DNS for up to 50 domains in one call |
| whois_lookup | Domain registration details (registrar, dates, nameservers) |
| response_time | HTTP latency with min/max/avg/p95 over multiple requests |
| port_scan | Scan common ports on a host — open/closed/filtered |
