For AI agents

These scanners are also callable as agent tools via the FEDLIN MCP server at https://mcp.fedlin.com/mcp (Streamable HTTP). Tools: scan_post_quantum, scan_domain_trust, scan_security_headers. Each takes a public hostname, is passive, and rate-limited. See llms.txt for the full agent context.
