About GuardM8 — AI Agent Firewall

GuardM8 is an AI-agent security firewall. Its single purpose is to inspect webpages locally for prompt injection, deceptive machine-readable content, risky WebMCP or browser-agent tools, sensitive-data fields, and consequential agent-triggered actions, then warn the user or request approval when appropriate.
