A WhatsApp Business MCP server lets AI agents read and write WhatsApp Business data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's WhatsApp Business MCP server ships with 58 pre-built actions, fully extensible via the Connector Builder — plus managed authentication, prompt injection defense, and optimized agent context. Connect it from MCP clients like Claude Desktop, Cursor, and VS Code, or from agent frameworks like OpenAI Agents SDK, LangChain, and Vercel AI SDK.
