Adds an MCP server exposing read tools (list_inbox, search, read_email) across three personal Gmail accounts using existing app passwords in /etc/openclaw/. Wired into claude-channels via --mcp-config. Slated for replacement by an OAuth2 Gmail+Calendar server in path 2. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# NixOS module for the Hara Gmail MCP server.

#
|
|
# Generates /etc/hara/gmail-accounts.json from declarative options and
|
|
# exposes the server binary through the dotfiles flake's pkgs set. Wiring
|
|
# the server into the claude-channels systemd service ExecStart is done
|
|
# by the host (phantom-ship.nix) so this module stays composable.
