Official Python library for Unity Catalog AI support
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has low install friction, carries no known vulnerabilities, and is licensed permissively under Apache-2.0. Install it if you need to integrate Unity Catalog functions into Python applications or GenAI agent workflows. Be aware that function execution occurs locally in your environment, so review security implications when executing agent-generated code.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or higher and a running Unity Catalog server instance.
- Avoid creating additional event loops in environments that already have a running loop (e.g., Jupyter Notebooks).
- Low install friction with a pure-Python wheel and five runtime dependencies.

What it is and what it does
unitycatalog-ai is a Python library that wraps the Unity Catalog client SDK to provide high-level APIs for managing and executing UC functions. It enables developers to register Python functions into a Unity Catalog server, retrieve function metadata, and execute those functions either synchronously or asynchronously. The library is designed to integrate UC functions as tools within GenAI agent workflows, allowing agents to call registered functions as part of their reasoning and action loops.
The library supports both standard function creation and wrapped functions, which bundle helper functions inline with a primary function to simplify code reuse. It enforces strict type validation based on function signatures and docstrings, and provides both async and sync interfaces to accommodate different application architectures. Core dependencies include pydantic for validation, cloudpickle for serialization, nest-asyncio for event loop management, and unitycatalog-client for the underlying REST communication.
Use it for
- Register Python utility functions into Unity Catalog and expose them as tools for GenAI agents to call during reasoning.
- Build modular function libraries where helper functions are bundled with primary functions using wrapped function creation.
- Integrate UC function execution into async-first applications or synchronous environments without rewriting function interfaces.
- Manage function lifecycle (create, retrieve, list, delete, execute) programmatically from Python applications.
- Enforce type safety and parameter validation on function execution by leveraging strict schema-based type checking.
