AMC — Agent Messaging Channel

A personal-scale messaging gateway that exposes the same four-tool MCP surface — and an equivalent REST surface — over both iMessage and Discord, normalizing their very different I/O models behind a single message envelope. It is the transport layer that Capo runs on.

Built decoupled-by-design across three independently replaceable layers: agent runtimes talk to a thin Python MCP wrapper (or directly over HTTP), a FastAPI adapter owns persistence and is the source of truth, and one connector per platform translates raw events into the normalized envelope. Full operator docs live at sequenzia.github.io/amc.

Key capabilities:

  • Four MCP tools — list_unread_messages, send_message, mark_read, get_message_context — exposed over stdio for Claude Code, Claude Desktop, and Codex clients
  • macOS-native adapter supervised by launchd, reading iMessage from chat.db and driving Messages.app via AppleScript, with a Discord gateway/REST connector
  • Swappable layers: replacing the agent framework, the MCP wrapper, or either connector requires no changes to the others
