And MCP makes the experience even better. With Whatsapp MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Whatsapp with - [ChatGPT](https://composio.dev/toolkits/whatsapp/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/whatsapp/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/whatsapp/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/whatsapp/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/whatsapp/framework/claude-cowork) - [Cursor](https://composio.dev/toolkits/whatsapp/framework/cursor) - [VS Code](https://composio.dev/toolkits/whatsapp/framework/vscode) - [OpenCode](https://composio.dev/toolkits/whatsapp/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/whatsapp/framework/openclaw) - [Hermes](https://composio.dev/toolkits/whatsapp/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/whatsapp/framework/cli) - [Google ADK](https://composio.dev/toolkits/whatsapp/framework/google-adk) - [LangChain](https://composio.dev/toolkits/whatsapp/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/whatsapp/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/whatsapp/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/whatsapp/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/whatsapp/framework/crew-ai) ## TL;DR ### Why use Composio? Apart from a managed and hosted MCP server, you will get: - CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool responses: Handle them to minimise context rot. - Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need. ## Connect Whatsapp to Codex ### How to install Whatsapp MCP in Codex ### Run the setup command Run this command in your terminal to add the Composio MCP server to Codex. ```bash codex mcp add composio --url https://connect.composio.dev/mcp ``` ## What is the Whatsapp MCP server, and what's possible with it? The Whatsapp MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your WhatsApp Business account. It provides structured and secure access to your business messaging platform, so your agent can perform actions like sending messages, managing templates, retrieving business info, and automating customer interactions on your behalf. - Automated messaging and contact sharing: Let your agent send messages or share contacts directly with customers who have initiated a conversation, making follow-ups and support quick and seamless. - Template management and automation: Easily create, retrieve, and delete WhatsApp message templates for marketing or transactional outreach, and keep your approved messages organized. - Business profile and phone management: Fetch and update business profile details or pull a full list of WhatsApp Business phone numbers connected to your account for easy management. - Media access and metadata retrieval: Direct your agent to download sent media or fetch detailed information about uploaded files—perfect for handling customer attachments or verifying uploads. - Template approval and status tracking: Automatically check the approval status of message templates, so your agent knows which templates are ready to use or need revision. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `WHATSAPP_CREATE_MESSAGE_TEMPLATE` | Create message template | Create a new message template for the WhatsApp Business Account.

IMPORTANT LIMITATION: WhatsApp Cloud API does not provide a native polling endpoint for message status. Status updates are ONLY delivered via webhooks in real-time. This trigger cannot directly poll the WhatsApp API for status updates. This trigger will return empty results as WhatsApp does not support this operation. To track message status updates, you must: 1. Set up a webhook endpoint to receive status notifications from WhatsApp 2. Store the webhook data in your own database 3. Use a different mechanism to query your stored webhook data For more information, see: - https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks | ## Creating MCP Server - Stand-alone vs Composio SDK The Whatsapp MCP server provides comprehensive access to Whatsapp operations through Composio.

With a standalone Whatsapp MCP server, the agents and LLMs can only access a fixed set of Whatsapp tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Whatsapp and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Codex? Yes, you can. Codex fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Whatsapp tools. ### Can I manage the permissions and scopes for Whatsapp while using Tool Router? Yes, absolutely. You can configure which Whatsapp scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Whatsapp data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
