Glittering-Coat-657 · reddit · 2026-08-23
The author released AgentGuard, an open-source Python project to control tool permissions for AI Agents at runtime.
- How it works: Intercepts tool requests before execution and enforces policies to allow or block actions.
- Use cases: Prevents unauthorized operations like sending emails, modifying databases, or accessing sensitive files.
- Community Feedback: Seeks input from developers using LangChain/LangGraph/MCP/CrewAI on their current security practices.
GitHub repository is available for testing.
