### Description (declared)

Passive external attack-surface scanner that returns a signed, exploitability-graded exposure claim. MacroCyber maps your external attack surface in real time and is built for the AI era: it finds the exposures AI-built software leaks (databases left open, leaked AI and model keys, exposed MCP servers and agent endpoints, open vector stores) alongside the classic gaps (spoofable email, takeover-prone subdomains, missing headers, weak TLS). It reports only observable facts, proves every finding, and ranks what an attacker, increasingly an autonomous agent, reaches first.
