I Built an Open-Source Tool to Catch AI Agents Going Rogue

Description and use

AgentSec is an open-source framework that tests AI agents for prompt injection, tool misuse, secret leaks, MCP attacks, and more.

Problem

AI agents can exhibit prompt injection, tool misuse, secret leaks, and MCP attacks, yet there is no systematic testing framework for these risks.

Outcome

AgentSec provides developers with a systematic way to detect and mitigate rogue behaviors in AI agents, improving security and reliability.

Workflow

• Define test scenarios for prompt injection, tool misuse, secret leaks, MCP attacks
• Implement test harness in AgentSec
• Run AI agent through test harness
• Collect and analyze results
• Iterate on agent design based on findings

Evidence

I built AgentSec: an open-source framework that tests prompt injection, tool misuse, secret leaks, MCP attacks & more.
