WhatsApp MCP
External messaging via MCP
Overview
WhatsApp MCP is a Model Context Protocol server that bridges AI assistants with the WhatsApp messaging platform. It enables AI workflows to read conversations, send messages, manage contacts, and automate communication through WhatsApp — the messaging platform used by over 2 billion people worldwide.
Several implementations exist including open-source projects like whatsapp-mcp (which connects through WhatsApp Web) and commercial offerings from API providers like Wassenger and WASender. These servers expose WhatsApp functionality as MCP tools, supporting text messages, media sharing, location sharing, contact cards, polls, and template messages through a standardized interface.
WhatsApp is the primary business communication channel in many regions and industries, particularly for client-facing communication, customer support, and external stakeholder engagement. AI access to WhatsApp conversations and the ability to send messages introduces significant governance challenges around data privacy, consent, and communication compliance — especially given that WhatsApp conversations often contain personal and commercially sensitive information.

Use Cases
Strategy-Aligned Use Cases
Client Communication Management
AI assistants can help manage high-volume client WhatsApp conversations by summarizing threads, suggesting responses, and drafting messages for human review before sending.
Customer Support Triage
Incoming WhatsApp messages can be analyzed, categorized by urgency and topic, and routed to appropriate team members with AI-generated context summaries and suggested responses.
Appointment and Update Notifications
Send structured notifications for appointments, delivery updates, and status changes using approved WhatsApp template messages, with AI handling the personalization and scheduling logic.
Conversation Analytics
Analyze WhatsApp communication patterns to identify response time trends, common customer inquiries, and sentiment patterns — providing actionable insights for customer experience improvement.
Considerations
- WhatsApp conversations frequently mix personal and professional communication on the same platform. AI access to message history may inadvertently expose personal conversations, creating privacy violations.
- Unlike internal tools, WhatsApp messages go to external recipients — clients, partners, and customers. An erroneous or inappropriate AI-generated message sent via WhatsApp can directly damage business relationships and brand reputation.
- WhatsApp communication is subject to privacy regulations including GDPR, which requires explicit consent for automated message processing. Organizations must ensure AI interactions with WhatsApp data comply with applicable data protection laws.
- WhatsApp enforces strict anti-spam policies. AI-initiated bulk messaging or inappropriate automation can result in account bans, disrupting business communication channels that organizations depend on.
- WhatsApp uses end-to-end encryption, but MCP servers that connect through WhatsApp Web or the Business API operate within the decrypted session. Organizations should understand the security model of their chosen implementation.
Stratafy Fit
WhatsApp MCP is a high-priority governance target for Stratafy, particularly for organizations that use WhatsApp for client-facing communication. The combination of external message delivery, personal data exposure, and regulatory compliance requirements makes ungoverned AI access to WhatsApp unacceptably risky. Stratafy provides critical controls including mandatory human approval for all outbound messages, scope restrictions that limit AI access to business-designated conversations, audit logging for regulatory compliance, and rate limiting to prevent account-damaging spam. Organizations in regions where WhatsApp is the primary business communication channel will find this governance essential.
