Microsoft Teams A2A

[!WARNING] Deprecated — This package was originally in preview, but we have decided to stop maintaining it before General Availability. We recommend using the official A2A Python SDK instead, which provides better long-term support for Agent-to-Agent protocol integrations.

Agent-to-Agent (A2A) protocol support for Microsoft Teams AI applications. Enables Teams agents to communicate and collaborate with other AI agents using standardized protocols.

Installation

pip install microsoft-teams-a2a

Or if using uv:

uv add microsoft-teams-a2a
