Best for
  • Teams or individuals using wacrm who want to increase CRM productivity via AI assistants
  • Developers who need self-hosting with full control over data and configuration
  • 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
  • Users not using wacrm or WhatsApp Business API
  • Those requiring an official, upstream-maintained MCP server (this is community-maintained)
  • 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 an API key from the wacrm instance; scopes define allowed actions
  • Read-only by default; enabling WACRM_ENABLE_WRITES allows contact create/update and message sending
  • Enabling WACRM_ENABLE_BROADCASTS allows mass broadcasts
  • 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
  • API key leakage could lead to unauthorized access or actions
  • With writes/broadcasts enabled, AI might execute unintended operations
  • Misconfiguration of the self-hosted instance may cause connection failures
  • 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
