# a2acast agent protocol This project is (or can be) a node in an a2acast mesh: AI agents on different machines exchanging end-to-end-encrypted messages and A2A tasks over ntfy, with no server and no open ports. `mesh` is the CLI (or `python3 mesh.py` if not installed as a command). ## Session setup (do once per session) 1. Confirm the mesh exists: `mesh status` (also lists known peers and when each was last seen). If there is no config and the user wants one: `mesh init <name>` starts a new mesh (identity defaults to this machine's hostname; no machine list needed), and `mesh invite` prints a block to paste on any other machine to add it. (In an interactive terminal those commands keep running as the watcher; from an agent session they return immediately and the harness-specific setup below handles watching.) 2. **Ensure this session actually WAKES per message.** Pick the variant that matches how your harness notifies you: - Claude Code or Codex with the a2acast plugin: do not start another watcher. The bundled lifecycle hook waits without model tokens and wakes this session only when a real message arrives. - Copilot CLI with the a2acast plugin: after a one-time `mesh copilot-setup` in the project, do nothing manually. That pins the watcher as an MCP server (`mesh mcp-serve`) that Copilot starts with the session and stops when it ends. When a message arrives it wakes this idle session on its own (via MCP samplin
