AG-UI Protocol Python SDK

AG-UI (Agent-User Interaction Protocol) is an open, lightweight, event-based protocol that standardizes how AI agents connect to user-facing applications. The `ag-ui-protocol` Python SDK provides strongly-typed data structures and event encoding for building AG-UI compatible agent servers. It's built on Pydantic for robust validation and automatic camelCase serialization for seamless frontend integration, and is currently at version 0.1.15. The library has a continuous release cadence, reflecting ongoing development in the AG-UI ecosystem.
