In this guide, I will explain the easiest and most secure way to connect your Fathom 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 Fathom with - [Antigravity](https://composio.dev/toolkits/fathom/framework/antigravity) - [OpenAI Agents SDK](https://composio.dev/toolkits/fathom/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/fathom/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/fathom/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/fathom/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/fathom/framework/codex) - [Cursor](https://composio.dev/toolkits/fathom/framework/cursor) - [VS Code](https://composio.dev/toolkits/fathom/framework/vscode) - [OpenCode](https://composio.dev/toolkits/fathom/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/fathom/framework/openclaw) - [Hermes](https://composio.dev/toolkits/fathom/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/fathom/framework/cli) - [Google ADK](https://composio.dev/toolkits/fathom/framework/google-adk) - [LangChain](https://composio.dev/toolkits/fathom/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/fathom/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/fathom/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/fathom/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/fathom/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 Fathom 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 Fathom 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 Fathom 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 Fathom 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 Fathom MCP server, and what's possible with it? The Fathom MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Fathom account. It provides structured and secure access so your agent can perform Fathom operations on your behalf. ## Supported Tools None listed. ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK Once connected, ChatGPT can access the Fathom MCP server via Composio to run actions that you authorize, directly in your chats and research workflows. ## Complete Code None listed. ## How to build Fathom MCP Agent with another framework - [Antigravity](https://composio.dev/toolkits/fathom/framework/antigravity) - [OpenAI Agents SDK](https://composio.dev/toolkits/fathom/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/fathom/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/fathom/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/fathom/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/fathom/framework/codex) - [Cursor](https://composio.dev/toolkits/fathom/framework/cursor) - [VS Code](https://composio.dev/toolkits/fathom/framework/vscode) - [OpenCode](https://composio.dev/toolkits/fathom/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/fathom/framework/openclaw) - [Hermes](https://composio.dev/toolkits/fathom/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/fathom/framework/cli) - [Google ADK](https://composio.dev/toolkits/fathom/framework/google-adk) - [LangChain](https://composio.dev/toolkits/fathom/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/fathom/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/fathom/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/fathom/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/fathom/framework/crew-ai) ## Related Toolkits - [Google Sheets](https://composio.dev/toolkits/googlesheets) - Google Sheets is a cloud-based spreadsheet tool for real-time collaboration and data analysis.

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