In this guide, I will explain the easiest and most secure way to connect your Agent mail account to ChatGPT via Composio Connect, so it can summarize unread updates from this morning, create draft replies to urgent messages, fetch contact details for recent senders, and more without ever putting your account credentials at risk. ## Also integrate Agent mail with - [Antigravity](https://composio.dev/toolkits/agent_mail/framework/antigravity) - [OpenAI Agents SDK](https://composio.dev/toolkits/agent_mail/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/agent_mail/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/agent_mail/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/agent_mail/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/agent_mail/framework/codex) - [Cursor](https://composio.dev/toolkits/agent_mail/framework/cursor) - [VS Code](https://composio.dev/toolkits/agent_mail/framework/vscode) - [OpenCode](https://composio.dev/toolkits/agent_mail/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/agent_mail/framework/openclaw) - [Hermes](https://composio.dev/toolkits/agent_mail/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/agent_mail/framework/cli) - [Google ADK](https://composio.dev/toolkits/agent_mail/framework/google-adk) - [LangChain](https://composio.dev/toolkits/agent_mail/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/agent_mail/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/agent_mail/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/agent_mail/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/agent_mail/framework/crew-ai) ## TL;DR ### Why use Composio over default connectors? - Apps with read and write access. Default connectors mostly can read your data. Composio's Agent mail integration lets ChatGPT take actions like creating drafts, sending updates, labeling records, and more. - 1,000+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce. - One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app. - Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand. - Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation. ## Connect Agent mail to ChatGPT ### Prerequisites - A ChatGPT account with Plus subscription or higher (Business, Enterprise, Edu, or Pro). We will use [ChatGPT Web](https://chatgpt.com). - Access to the Agent mail workspace you want to connect. - [Composio MCP](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=chatgpt&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fchatgpt). Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account. ### Step-by-step: Connect Agent mail to ChatGPT ### 1. Enable Developer Mode In ChatGPT, go to Settings > Apps > Advanced settings and turn on Developer Mode. ### 2. Add the MCP server Click Create app, then paste the Composio MCP server URL: ```bash https://connect.composio.dev/mcp ``` ## What is the Agent mail MCP server, and what's possible with it? The Agent mail MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Agent mail account. It provides structured and secure access to your agent's dedicated inbox, so your agent can send emails, receive incoming messages, fetch specific conversations, and automate email-based workflows on your behalf. - Automated email sending: Instruct your agent to compose and send emails to any recipient, perfect for status updates, notifications, or outreach. - Message listing and inbox scanning: Let your agent quickly list all recent messages in the inbox to summarize, monitor, or trigger follow-up actions. - Targeted message retrieval: Have your agent fetch a specific message by ID, making it easy to pull full email content for context-aware decisions or replies. - Streamlined agent-to-agent communication: Enable your AI to directly interact with other agents or services via email, automating routine communication flows. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `AGENT_MAIL_CREATE_INBOX` | Create Inbox | Create a new AgentMail inbox via API.

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