pydantic-ai-backend

What it does

pydantic-ai-backend provides foundational backend services for Pydantic AI agents, offering secure file operations, isolated execution environments, and granular permission management. It enables developers to build AI agents that safely handle file I/O, execute untrusted code, and manage multi-user access without security risks.

Key features

• Console tools for secure file operations (read, write, delete)
• Docker-isolated sandboxes for safe code execution
• Permission system with preset access control configurations
• Multi-storage support: in-memory, local filesystem, or containerized backends
• Multi-user handling with role-based access controls
• Testing utilities for agent validation

How to set up

Install via pip: pip install pydantic-ai-backend. Configure storage backend (in-memory, local, or Docker). Define permission presets for your use case. Initialize the backend in your Pydantic AI agent configuration and pass storage and permission instances to your agent tools.
