Show HN: AgentGate – Fast authorization gateway for AI agent tools (github.com)

AgentGate has been introduced as an innovative authorization gateway designed specifically for the safe execution of autonomous AI agent tools. This tool acts as a proxy that intercepts calls to AI agents in real-time, assessing risks associated with prompt injection and unauthorized actions before they affect production systems. With a response time of less than 40 milliseconds, AgentGate employs a fine-tuned neural classification model to enforce security policies effectively, ensuring that potentially harmful actions are denied or escalated for review. The significance of AgentGate lies in its ability to provide a robust defense against prompt injection vulnerabilities, which can lead agents to perform unintended destructive actions. By integrating a deterministic access control mechanism into the workflow, it replaces traditional LLM-as-a-judge systems that are slower and more prone to exploitation. AgentGate's architecture includes a FastAPI-based decision engine, PostgreSQL for logging, and a user-friendly dashboard that allows operators to monitor and manage tool calls in real-time, enhancing security and compliance across AI deployments.
