Best for
  • Teams that need AI agents to access Trello and manage project tasks.
  • Developers who want to automate board workflows with AI assistants.
  • Individuals who want to talk to Claude from their personal WhatsApp number
  • Developers comfortable configuring from a terminal and using the Claude Code development flag
  • Automation scenarios needing remote tool approval from a phone
Not for
  • Scenarios requiring only read-only access without real-time interaction.
  • Environments with high performance requirements that cannot tolerate Bun dependency.
  • Compliance scenarios requiring the official WhatsApp Business API or a Meta developer account
  • Teams needing officially hosted, multi-tenant, or cloud multi-instance deployment
  • Environments unable to guarantee only one client instance at a time
  • Users expecting voice transcription without setting up mlx-whisper themselves
Required permissions
  • Requires Trello API key and token to access Trello data on behalf of the user.
  • By default, can access all boards and workspaces the token has access to.
  • Optional restriction to specific workspaces via environment variable TRELLO_ALLOWED_WORKSPACES.
  • Read and send WhatsApp messages as your personal number
  • Access the local runtime state directory ~/.whatsapp-channel/ (auth, allowlists, group configs, inbox)
  • Read and write local repository files and run scripts (e.g. bun scripts/access.ts, scripts/watchdog.sh)
  • Optional local voice transcription (ffmpeg and an mlx-whisper environment)
Risks and side effects
  • Risk of API credential leakage; handle keys and tokens securely.
  • AI may accidentally perform destructive operations, such as deleting cards or comments.
  • Improper use may trigger Trello rate limits.
  • Messages Claude sends appear from your own number and are indistinguishable to recipients
  • WhatsApp allows one linked-device session per account; running two servers makes them kick each other off
  • Access-control commands are deliberately not MCP tools (terminal-only); exposing them to the message side risks prompt injection
  • Session waking depends on the Claude Code channel extension; other clients get no push
  • A known Claude Code client bug (#37933) may cause messages not to arrive, a client-side issue
  • Launching with --dangerously-load-development-channels carries risk, so verify the source is trustworthy
