It's basically `curl` for A2A agents.\n\n\n## Installation\n\n```bash\npip install ca2a\n```\n\n\n## Usage\n\n```bash\nca2a -h\n```\n\n```\nusage: ca2a [-h] [-v] url method [items ...]\n\nA command-line utility for interacting with A2A agents.\n\npositional arguments:\n  url            The URL to connect to the A2A agent\n  method         The method to be invoked\n  items          The parameter values (in the form of `key=string_value` or `key:=json_value`), or the header values (in the form of `key:value`)\n\noptions:\n  -h, --help     show this help message and exit\n  -v, --verbose  Enable verbose output showing the JSON-RPC request/response\n```\n\n\n## Quick Start\n\nRun an A2A agent (see [Helloworld Example](https://github.com/a2aproject/a2a-python#helloworld-example)):\n\n```bash\ngit clone https://github.com/a2aproject/a2a-samples.git\ncd a2a-samples/samples/python/agents/helloworld\nuv run .\n```\n\nSend a message to the agent:\n\n```bash\nca2a http://localhost:9999 message/send message:='{\n  \"role\": \"user\",\n  \"parts\": [{\"kind\": \"text\", \"text\": \"Hello\"}],\n  \"messageId\": \"msg_123\",\n  \"taskId\": \"task_123\"\n}'\n```\n\nSend a streaming message to the agent:\n\n```bash\nca2a http://localhost:9999 message/stream message:='{\n  \"role\": \"user\",\n  \"parts\": [{\"kind\": \"text\", \"text\": \"Hello\"}],\n  \"messageId\": \"msg_123\",\n  \"taskId\": \"task_123\"\n}'\n```\n\n\n## Related Projects\n\n[cMCP][2]: A command-line utility for interacting with MCP servers.\n\n\n## License\n\n[MIT][3]\n\n\n[1]: https://a2a-protocol.org/\n[2]: https://github.com/RussellLuo/cmcp\n[3]: http://opensource.org/licenses/MIT\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frussellluo%2Fca2a","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frussellluo%2Fca2a","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frussellluo%2Fca2a/lists"}
