Exposed MCP Tools for AI Assistants

Once connected, your AI model will automatically discover and invoke the following tools:

Tool check_ssl_certificate(domain: string)

Inspects a website's SSL/TLS certificate in real-time. Returns exact expiration countdown, validity range, issuer CA, covered SANs, SHA-256 fingerprint, and TLS cipher strength.

Tool inspect_caa_policy(domain: string)

Queries DNS Certification Authority Authorization (CAA) records (RFC 8659) to check which CAs are permitted to issue certificates and whether wildcard certs are restricted.

Tool check_security_headers(domain: string)

Inspects HTTP transport security headers on port 443 including HSTS (Strict-Transport-Security), HSTS Preload list eligibility, CSP, and calculates a security grade (A+ to F).

Tool get_cli_verification_commands(domain: string, tool?: string)

Generates pre-configured terminal commands (OpenSSL, cURL, Python socket, or Certbot renewal fix) tailored to a specific domain name.
