You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Whatsapp account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Whatsapp with - [ChatGPT](https://composio.dev/toolkits/whatsapp/framework/chatgpt) - [Antigravity](https://composio.dev/toolkits/whatsapp/framework/antigravity) - [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) - [Grok Bot](https://composio.dev/toolkits/whatsapp/framework/grok-bot) - [Codex](https://composio.dev/toolkits/whatsapp/framework/codex) - [Kimi Code](https://composio.dev/toolkits/whatsapp/framework/kimi) - [Grok Build](https://composio.dev/toolkits/whatsapp/framework/grok-build) - [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) - [Pi](https://composio.dev/toolkits/whatsapp/framework/pi-agent) - [DeepSeek Harness](https://composio.dev/toolkits/whatsapp/framework/deepseek) - [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) - [Pydantic AI](https://composio.dev/toolkits/whatsapp/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/whatsapp/framework/autogen) ## TL;DR ### How Atomic Agent connects to Whatsapp Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect Whatsapp to Atomic Agent ### Connect Whatsapp to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in Whatsapp. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Whatsapp account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## 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. Templates must be approved by WhatsApp before they can be used. Templates are required for marketing messages and messages sent outside the 24-hour window. | | `WHATSAPP_DELETE_MESSAGE_TEMPLATE` | Delete message template | Delete a message template from the WhatsApp Business Account by name. This permanently removes the template and it cannot be recovered. When you delete a template by name, all templates with that name across all languages will be deleted. Names of deleted templates cannot be reused for 30 days. Important: Only delete templates that are no longer needed, as this operation is irreversible. | | `WHATSAPP_GET_BUSINESS_PROFILE` | Get business profile | Get the business profile information for a WhatsApp Business phone number. This includes business details like description, address, website, and contact info. | | `WHATSAPP_GET_MEDIA_INFO` | Get media info | Get metadata and download URL for uploaded WhatsApp media.

The download URL can be used to retrieve the actual media file. | | `WHATSAPP_GET_MESSAGE_TEMPLATES` | Get message templates | Get all message templates for the WhatsApp Business Account. Templates are required for sending messages outside the 24-hour window and for marketing/utility messages. | | `WHATSAPP_GET_PHONE_NUMBER` | Get phone number | Retrieve detailed information about a specific WhatsApp Business phone number. Returns phone number details including verification status, quality rating, display number, verified business name, throughput limits, and webhook configuration. Use this to check phone number status, settings, and capabilities. To get available phone number IDs, first call WHATSAPP_GET_PHONE_NUMBERS. | | `WHATSAPP_GET_PHONE_NUMBERS` | Get phone numbers | Retrieve all phone numbers registered to your WhatsApp Business Account. Returns phone number IDs, display numbers, verification status, quality ratings, and messaging throughput limits. Use the phone number ID from the response to send WhatsApp messages via other API actions. | | `WHATSAPP_GET_TEMPLATE_STATUS` | Get template status | Get the status and details of a specific message template. This is useful for checking if a template has been approved, rejected, or is still pending review. | | `WHATSAPP_SEND_CONTACTS` | Send contacts | Send contacts WhatsApp number. Note: The message will be delivered to the recipient only if they have initiated a conversation first. | | `WHATSAPP_SEND_INTERACTIVE_BUTTONS` | Send interactive buttons | Send an interactive button message with up to 3 reply buttons to a WhatsApp user. Interactive button messages allow recipients to quickly respond by tapping predefined buttons. Perfect for yes/no questions, multiple choice selections, quick actions, or call-to-action scenarios. IMPORTANT REQUIREMENTS: - The recipient must be a registered WhatsApp user - The recipient must have messaged your business first within the last 24 hours (WhatsApp's customer service window) - You can include 1-3 buttons per message - Each button can have a title (max 20 chars) and unique ID (max 256 chars) Use cases: Customer service menus, appointment confirmations, feedback collection, product selections. | | `WHATSAPP_SEND_INTERACTIVE_LIST` | Send interactive list | Send an interactive list message to a WhatsApp number. List messages display a menu of options organized into sections. Users tap a button to view the list and select one option. Perfect for product catalogs, service menus, or guided workflows.

Note: Recipients must have messaged you first within the last 24 hours to receive this message. | | `WHATSAPP_SEND_LOCATION` | Send location | Send a location message with coordinates, name, and address to a WhatsApp user. This action allows you to share location information through WhatsApp Business API. The location message includes latitude/longitude coordinates, a location name, and address. Important: The recipient must have an active WhatsApp account. Additionally, you can only send free-form messages (like location messages) within the 24-hour customer service window after the recipient has initiated contact with your business. Outside this window, you must use approved message templates. Common error codes: - 133010: Recipient's phone number doesn't have a WhatsApp account - 131026: Message undeliverable (recipient may have blocked your business number) - 131047: Re-engagement message (outside 24-hour window, need to use template) | | `WHATSAPP_SEND_MEDIA` | Send media | Send a media message to a WhatsApp number. Note: The media will be delivered to the recipient only if they have texted first. | | `WHATSAPP_SEND_MEDIA_BY_ID` | Send media by | Send media using a media ID from previously uploaded media.

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 | ## Troubleshooting ### Why is my API key rejected? Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use Whatsapp from Atomic Agent With your account connected, ask Atomic Agent to work with Whatsapp in natural language. You can connect more apps through the same Composio integration as you need them.

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 Atomic Agent? Yes, you can. Atomic Agent 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)
