Handoffs

One agent passes the conversation to another agent, which takes over.

Subagents / agents as tools

A main agent calls other agents like tools and gets their result back, each with its own context.

Not shown in the docs.

Graph or workflow

You define steps and edges (or a workflow), and the framework runs agents and functions through them.

Group chat / crew

Several agents with roles work together on a task, coordinated by a manager or a selection rule.

Not shown in the docs.

Human in the loop

The run pauses for a person to approve, edit or answer before it continues.

Hosted runtime

Self-hosted only (none documented)

Yes. LlamaIndex (Workflows / Agents)'s documentation shows agents using tools from MCP servers.

Its documentation does not cover A2A as of 2026-10-07.
