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

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

  • 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
