Verdict MCP

An action firewall for AI agents that provides a verdict (allow, review, or block) before executing risky operations. It detects prompt injection, shell command risks, and tool misuse by analyzing untrusted content and proposed actions, returning scores and reasons to prevent data loss or security breaches.
