And MCP makes the experience even better. With Wati MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Wati with - [OpenAI Agents SDK](https://composio.dev/toolkits/wati/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/wati/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/wati/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/wati/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/wati/framework/openclaw) - [Hermes](https://composio.dev/toolkits/wati/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/wati/framework/cli) - [Google ADK](https://composio.dev/toolkits/wati/framework/google-adk) - [LangChain](https://composio.dev/toolkits/wati/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/wati/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/wati/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/wati/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/wati/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 Wati to Codex ### How to install Wati 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 Wati MCP server, and what's possible with it? The Wati MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Wati WhatsApp Business account. It provides structured and secure access to your business messaging, so your agent can add contacts, send WhatsApp messages, update contact details, and retrieve team information automatically on your behalf. - Automated contact management: Have your agent add new WhatsApp contacts, ensuring customers are registered before any communication starts. - Proactive messaging via WhatsApp: Empower your agent to send session messages to customers for support, marketing, or updates within the active session window. - Contact attribute updates: Let your agent update existing contact information or custom attributes, so your customer data stays fresh and relevant. - Team coordination and retrieval: Quickly fetch lists of your Wati teams, making it easy for your agent to understand and act on organizational structure. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `WATI_ADD_CONTACT` | Add Contact | Tool to add a new contact in WATI. Use when registering a customer's WhatsApp number before sending messages. | | `WATI_GET_TEAMS` | Get Teams | Tool to retrieve a list of teams from WATI. Use after authenticating when you need to enumerate all available teams. | | `WATI_SEND_SESSION_MESSAGE` | Send Session Message | Tool to send a session message to a specified WhatsApp number. Use when you need to deliver a free-form text within an active 24-hour session window. | | `WATI_UPDATE_CHAT_STATUS` | Wati update chat status | Update the status of a chat/conversation in WATI Team Inbox. This action allows you to change the status of a customer's chat to help manage ongoing conversations. Available statuses: - OPEN: Active, two-way conversation - PENDING: Waiting for customer's response - SOLVED: Issue has been resolved - BLOCK: Prevent further communication with the contact | | `WATI_UPDATE_CONTACT_ATTRIBUTES` | Update Contact Attributes | Tool to update attributes of an existing contact. Use after confirming the contact exists and you need to modify its custom attributes. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Wati MCP server provides comprehensive access to Wati operations through Composio. Once connected, you can perform all major Wati actions directly from Codex using natural language commands. ## Complete Code None listed. ## Conclusion ### Conclusion You've successfully integrated Wati with Codex using Composio's MCP server.

With a standalone Wati MCP server, the agents and LLMs can only access a fixed set of Wati tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Wati 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 Wati tools. ### Can I manage the permissions and scopes for Wati while using Tool Router? Yes, absolutely. You can configure which Wati 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 Wati data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
