Agent-to-Agent Protocol in Copilot Studio (Generally Available)

Copilot Studio agents can hand work to other agents, including ones built outside Copilot Studio.

Details

Uses the agent-to-agent protocol, a shared standard letting agents call each other across different vendors and platforms
You can build one front-door agent that routes each request to the right specialist behind it
Connects to agents in your own environment and to outside ones such as Microsoft Fabric data agents

Best for

Splitting a large process across specialist agents instead of one agent doing everything

When to use it

A single agent's instructions are growing long and unfocused because it handles too many jobs

Who benefits

Teams running several agents that need to work together
