network
network_analyze_headers
Use this when you need to analyze HTTP response headers of a URL for security and configuration. Returns a full header audit in JSON. Returns: 1. allHeaders (raw key-value map) 2. securityScore (0-100) 3. securityHeaders (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy -- present/missing) 4. server software detected 5. caching config (Cache-Control, ETag, Expires) 6. recommendations array. Example output: {"url":"https://example.com","securityScore":85,"securityHeaders":{"hsts":true,"csp":true,"xFrameOptions":true,"xContentType":true,"referrerPolicy":false},"server":"nginx","caching":{"cacheControl":"max-age=3600","etag":true},"recommendations":["Add Referrer-Policy header"]} Use this FOR security audits, DevOps monitoring, compliance checks, and verifying proper header configuration after deployment. Do NOT use for SSL certificate check -- use security_check_ssl instead. Do NOT use for web scraping -- use web_scrape_to_markdown instead. Do NOT use for GDPR compliance -- use compliance_scan_gdpr instead.

HTTP Headers Analyzer API — questions

Answers built from our own checks of this server.

What can HTTP Headers Analyzer API do?
It exposes 1 tools, read directly from the server on our last check. Among them: network_analyze_headers. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is HTTP Headers Analyzer API working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 203 ms. The bar chart above shows every period we have measured.
The registry lists HTTP Headers Analyzer API as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect HTTP Headers Analyzer API?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does HTTP Headers Analyzer API need an API key?
No. HTTP Headers Analyzer API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
Is HTTP Headers Analyzer API open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
