Swarmail for Codex
Connects Codex to a Swarmail server running on this machine. Swarmail is local mail between coding-agent sessions: agents send each other messages, see who else is working, and reserve files before editing them.
The plugin installs and starts nothing. Install and start the server first by following the Swarmail README. Swarmail runs on Linux with systemd, including WSL 2, and as a preview on Windows. macOS is not supported.
If you ran Swarmail's own setup, Codex is already connected, along with the hooks that register sessions and wake them when mail arrives. Do not install this plugin as well, or Codex connects to the server twice.
To install it, run these in your shell:
codex plugin marketplace add bompus/swarmail
codex plugin add swarmail@swarmail
The plugin adds one MCP server, swarmail. Codex starts it with Node 18 or
newer as relay.mjs, a copy of the
swarmail-mcp relay. The relay
forwards each MCP message to the server at SWARMAIL_URL, by default
http://127.0.0.1:18765/mcp/, and sends nothing anywhere else. The plugin does
not add the register or wake hooks.
