Tool-Guardian-Proxy

This is a proxy layer that sits between Claude and your actual tool implementations to add safety guardrails during execution. The concept is straightforward: instead of Claude calling your tools directly, requests route through this guardian service which can validate, rate limit, or block dangerous operations before they hit your systems. You'd reach for this when you're exposing potentially risky tools like file system access, shell commands, or API calls with side effects and want a security checkpoint that can enforce policies or require human approval for certain actions. The implementation runs as a hosted service on Vercel, so there's no local setup required.
