> This is a method of the [**AgentTeam**](../classes/AgentTeam) class in the [**agents**](../modules/agents) module.

Launch all agents as a single API endpoint (HTTP) or an MCP server.
In HTTP mode, the endpoint accepts a query and processes it through all agents in sequence.
In MCP mode, an MCP server is started, exposing a tool to run the agent workflow.
