Agent OPFOR: Open-Source AI Agent Security Testing Tool
grajmanu · reddit · 2026-07-07
A developer has open-sourced Agent OPFOR, a tool designed for adversarial simulation testing against AI agents and MCP servers. It supports running the OWASP test suite to launch multi-round adversarial attacks on prompts, tool calls, MCP endpoints, memory, and reasoning chains. An LLM judge then scores the results and leaves a complete audit trail.
The tool also offers a browser extension (allowing tests to run in any chat interface without code) and an autonomous "hunting mode": given an endpoint and a target, the multi-agent system adaptively launches attack campaigns and generates reports.
