A2A Servers

This sample demonstrates how to implement a travel agent built on Semantic Kernel and exposed through the A2A protocol. It showcases: Multi-turn interactions: The agent may request clarifications Streaming responses: Returns incremental statuses Conversational memory: Maintains context (by leveraging Semantic Kernel’s ChatHistory) Push notifications: Uses webhook-based notifications for asynchronous updates External plugins (SK Agents & Frankfurter API): Illustrates how an Semantic Kernel Agents are used as plugins, along with APIs, that can be called to generate travel plans and fetch exchange rates

This sample demonstrates a simple image generation agent built with CrewAI and exposed through the A2A protocol.

This sample uses the Agent Development Kit (ADK) to create a simple "Expense Reimbursement" agent that is hosted as an A2A server. This agent takes text requests from the client and, if any details are missing, returns a webform for the client (or its user) to fill out. After the client fills out the form, the agent will complete the task.

This sample demonstrates a currency conversion agent built with LangGraph and exposed through the A2A protocol. It showcases conversational interactions with support for multi-turn dialogue and streaming responses.
