# reimagined-barnacle This little GitHub repository introduces the agent to agent (A2A) protocol idea. I build and explain what the A2A is about, and why it's still incomplete. #### Companion Medium article: [Agent-to-Agent protocols: A story still being written!](https://medium.com/@tituslhy/agent-to-agent-protocols-a-story-still-being-written-e7e1ffbf3e80) <p align="center"> <img src="./images/groupchat_agents.png"> </p> There is therefore no "app". The main notebook is: `test_a2a.ipynb`. I also include a simple echo agent (that simply echoes whatever it receives) as a simple example of A2A. It is adapted from this [HuggingFace article](https://huggingface.co/blog/lynn-mikami/agent2agent). ## Setup We will be cloning only the folders from A2A/samples/python/common from the [official A2A repository](google.github.io/A2A/). First: fork the repository into your own account! Then type the following commands: ``` git clone --depth 1 https://github.com/your-username/A2A.git A2A cd A2A git sparse-checkout init --cone #enable sparse checkout git sparse-checkout set samples/python/common #set sparse checkout for common folder git checkout #checkout the files mv samples/python/common . #move all scripts from the common folder into the root rm -rf samples # optional: remove the extra 'samples' folder #remove the samples folder ``` To spin up the MCP tool type: ``` python tool_protocols/exchange_rate_tool.py ``` To spin up the A2A server: ``` python agent_protocols/current_exchange_server.py ``` ## Repository Layout ``` . |- A2A <- Cloned from my fork of Google's A2A server |- agent_clients <- Folder containing scripts to invoke specific agent clients |- agent_protocols <- Folder containing server side scripts to serve agent clients |- notebooks <- Notebooks showing how I spin up the various services |- src <- Source code folder | |- agent.py <- The MCP agent definition | |- ping_client.py <- Scripts to invoke A2A clients | |- task_manager.py <- TaskManager object for the MCP agent in the A2A protocol |- tool_protocols | |- exchange_rate_tool.py <- MCP tool to return exchange rates. |- utils <- utility functions folder to deconflict pathing |- test_a2a.ipynb <- The main notebook showcasing interacting with agents via the A2A protocol. ```
