web-intel-mcp
MCP server that gives AI agents web intelligence capabilities. DNS lookups, SSL checks, tech stack detection, page metadata, link safety analysis — all in one package.
Why
AI agents can't do DNS lookups, read SSL certificates, or detect web technologies natively. This MCP server adds those capabilities with zero configuration.
Tools
| Tool | What it does |
|---|---|
web_investigate | Complete website investigation — DNS, SSL, tech stack, metadata, link safety in one call |
web_dns | DNS records (A, AAAA, MX, NS, TXT, CNAME) + mail provider detection |
web_ssl | SSL certificate details — issuer, expiry, validity, SANs |
web_tech_stack | Detect frameworks, CMS, analytics, CDN, hosting, security headers |
web_meta | Page title, description, Open Graph, Twitter cards, canonical URL |
web_link_safety | URL safety verdict — safe/suspicious/dangerous with risk score |
Install
Claude Code
claude mcp add web-intel node /path/to/web-intel-mcp/index.js
Or add to .mcp.json:
{
"mcpServers": {
"web-intel": {
"command": "node",
"args": ["/path/to/web-intel-mcp/index.js"]
}
}
}
npx (no install)
{
"mcpServers": {
"web-intel": {
"command": "npx",
"args": ["web-intel-mcp"]
}
}
}
Examples
"Check if this website is legit"
→ Agent calls web_investigate → gets trust score, SSL status, tech stack, safety signals
"What DNS records does example.com have?"
→ Agent calls web_dns → gets A, MX, NS records + mail provider
"Is this link safe to click?"
→ Agent calls web_link_safety → gets safe/suspicious/dangerous verdict
"What framework is this site built with?"
→ Agent calls web_tech_stack → gets Next.js, React, Cloudflare, etc.
No API keys needed
Everything runs locally using Node.js built-in dns and https modules. No external API dependencies. No rate limits. No costs.
