AgentFS

AgentFS is an isolated filesystem for AI agents that provides secure tool access and audit trails.

AgentFS is a filesystem isolation tool designed specifically for AI agents. It provides isolated filesystem access backed by a SQLite file, allowing agents to run CLI tools and perform development workflows safely. Original files remain protected through copy-on-write until modifications are applied and reviewed. The platform tracks every file read, write, and modification for complete audit visibility. It offers SDKs in TypeScript, Python, and Rust for building custom agents.
