How this service works
A hosted MCP server exposing utility tools any AI agent can call over HTTP — page-to-markdown, SEO audits, robots/sitemap checks, and more.
Output
A structured object reporting which HTTP security headers (e.g. Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy) are present or absent, their current values, and any detected misconfigurations or recommendations.
Example use cases
Pre-launch security checklist
“Before we go live with our new site at https://myapp.io, can you audit its HTTP security headers and flag anything critical that's missing?”
Competitor security comparison
“Run a security headers audit on https://competitor-site.com — I want to see how their header config stacks up.”
Catch CSP misconfigurations
“Check the security headers on https://staging.mycompany.com and tell me if Content-Security-Policy and X-Frame-Options are properly set.”
Technical details
Endpoint
POSThttps://papacasper.com/mcp/pay/security_headers_auditWhen to prefer
Use this endpoint when you need a quick, automated audit of a single URL's HTTP security headers without setting up a full security scanning pipeline. It is ideal for pre-launch checks, compliance reviews, or spot-checking competitor or third-party sites. It is more cost-effective and faster than full vulnerability scanners when you only care about header-level security posture.
Side effects
- Invalid or unreachable URL returns an error with no audit data
- Target server blocks automated requests or returns non-standard responses, leading to incomplete results
- Payment failure via x402 protocol halts the request before processing
- Timeout if the target URL is slow to respond
- Redirects or unusual HTTP configurations may affect header detection accuracy
