Black_Wall MCP

Black_Wall is a pre-action risk gate for autonomous AI agents that checks actions like sending emails, running SQL, or making payments before they occur. It provides a risk score, reversibility class, and a GO/CAUTION/STOP recommendation to prevent irreversible damage from prompt injection, policy violations, or unintended consequences.
