And MCP makes the experience even better. With 2chat MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate 2chat with - [OpenAI Agents SDK](https://composio.dev/toolkits/_2chat/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/_2chat/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/_2chat/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/_2chat/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/_2chat/framework/openclaw) - [Hermes](https://composio.dev/toolkits/_2chat/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/_2chat/framework/cli) - [Google ADK](https://composio.dev/toolkits/_2chat/framework/google-adk) - [LangChain](https://composio.dev/toolkits/_2chat/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/_2chat/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/_2chat/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/_2chat/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/_2chat/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 2chat to Codex ### How to install 2chat 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 2chat MCP server, and what's possible with it? The 2chat MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your 2chat account. It provides structured and secure access to your messaging channels, so your agent can perform actions like sending and receiving WhatsApp messages, managing contacts, monitoring API usage, and automating group workflows on your behalf. - Contact management and automation: Quickly add new contacts or retrieve existing ones, allowing your agent to keep your WhatsApp and text channels up to date and organized. - API usage monitoring: Effortlessly check your current API usage and quotas, so your agent can help prevent service interruptions or overages. - Webhook subscription review: Let your agent list and audit all active webhook subscriptions for your messaging channels, making it easy to monitor integrations and event triggers. - Credential validation and account status: Have your agent validate API keys and fetch account information to ensure secure and reliable operation before performing messaging tasks. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `_2CHAT_CREATE_CONTACT` | Create Contact | Tool to create a new contact in your 2Chat account. Use after gathering and verifying first name and at least one contact detail (email, phone, or address). | | `_2CHAT_GET_API_USAGE_INFO` | Get API Usage Info | Tool to retrieve current API usage and account information. Use when you need to monitor your remaining quotas before sending more requests. | | `_2CHAT_LIST_CONTACTS` | List Contacts | Tool to list all contacts in your 2Chat account. Use when you need to retrieve your contact list after confirming your account connection. | | `_2CHAT_LIST_WEBHOOKS` | List Webhook Subscriptions | List all configured webhook subscriptions for WhatsApp and phone call events. Use this when you need to audit, review, or retrieve UUIDs of your active webhook subscriptions. Returns details including webhook UUID, event type, channel UUID, callback URL, and creation timestamp. | | `_2CHAT_TEST_API_KEY` | Test API Key | Tool to validate your API key and retrieve account info. Use when confirming credentials before performing other operations. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The 2chat MCP server provides comprehensive access to 2chat operations through Composio. Once connected, you can perform all major 2chat actions directly from Codex using natural language commands. ## Complete Code None listed. ## Conclusion ### Conclusion You've successfully integrated 2chat with Codex using Composio's MCP server. Now you can interact with 2chat directly from your terminal, VS Code, or the Codex App using natural language commands. Key benefits of this setup: - Seamless integration across CLI, VS Code, and standalone app - Natural language commands for 2chat operations - Managed authentication through Composio - Access to 20,000+ tools across 1000+ apps for cross-app workflows - CodeAct workbench for complex tool chaining Next steps: - Try asking Codex to perform various 2chat operations - Explore cross-app workflows by connecting more toolkits - Build automation scripts that leverage Codex's AI capabilities ## How to build 2chat MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/_2chat/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/_2chat/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/_2chat/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/_2chat/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/_2chat/framework/openclaw) - [Hermes](https://composio.dev/toolkits/_2chat/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/_2chat/framework/cli) - [Google ADK](https://composio.dev/toolkits/_2chat/framework/google-adk) - [LangChain](https://composio.dev/toolkits/_2chat/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/_2chat/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/_2chat/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/_2chat/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/_2chat/framework/crew-ai) ## Related Toolkits - [Gmail](https://composio.dev/toolkits/gmail) - Gmail is Google's email service with powerful spam protection, search, and G Suite integration.

With a standalone 2chat MCP server, the agents and LLMs can only access a fixed set of 2chat tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from 2chat 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 2chat tools. ### Can I manage the permissions and scopes for 2chat while using Tool Router? Yes, absolutely. You can configure which 2chat 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 2chat data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
