Common questions about integrating Holiday API MCP Server with AutoGen.

How does AutoGen connect to MCP servers?

Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call Holiday API tools during their conversation turns.

Can different agents have different MCP tool access?
