Handler

# Handler [](https://github.com/alDuncanson/handler/actions/workflows/ci.yml) An [A2A](https://a2a-protocol.org/latest/) Protocol client TUI and CLI.  ## Run This project is managed with [uv](https://docs.astral.sh/uv/), so you can run Handler in a temporary, isolated environment: ```bash uvx git+https://github.com/alDuncanson/handler ``` or, install it globally: ```bash uv tool install git+https://github.com/alDuncanson/handler ``` ## Use Now you can use Handler: ```bash handler ``` If you don't have an A2A server to connect to, Handler provides a local A2A server agent: ```bash handler server ``` > The server agent requires [Ollama](https://ollama.com/) to be running locally. By default it connects to `http://localhost:11434` and uses the `qwen3` model. > > 1. Install and run Ollama > 2. Pull the model: `ollama pull qwen3` > 3. (Optional) Configure via environment variables: `OLLAMA_API_BASE` and `OLLAMA_MODEL` ### TUI Interactive terminal user interface: ```bash handler tui ``` ### CLI Fetch agent card from A2A server: ```bash handler card http://localhost:8000 ``` Send a message to an A2A agent: ```bash handler send http://localhost:8000 "Hello World" ``` ## Contributing See [CONTRIBUTING.md](CONTRIBUTING.md) for architecture and development instructions.
