# firewall

> Use this tool when you need to protect AI agents from potential security threats and ensure safe interactions. The firewall injects token safety instructions into any AI agent context, providing an invisible layer of protection against malicious activities. It is particularly useful in scenarios where AI agents are exposed to untrusted inputs or operate in high-risk environments.
