# MCP Action Firewall

> Use this tool when you need to add a security layer between AI agents and MCP servers to prevent unauthorized actions. The MCP Action Firewall intercepts high-risk tool calls, requiring OTP-based human approval before execution, and acts as a configurable circuit breaker to block dangerous actions. It is ideal for use cases where sensitive operations require an additional verification step to ensure safety and compliance.
