It takes action across your apps and files, stays with a project for hours, and turns a goal into finished materials like sheets, slides, and docs - not just answers. In this guide, I will explain the easiest and most secure way to connect your Octagon account to ChatGPT Work via Composio Connect, so it can search SEC filings, summarize earnings transcripts, fetch stock metrics, and analyze prediction-market signals through natural language commands without ever putting your account credentials at risk. ## Also integrate Octagon MCP with - [Claude Cowork](https://composio.dev/toolkits/octagon_mcp/framework/claude-cowork) - [Hermes](https://composio.dev/toolkits/octagon_mcp/framework/hermes-agent) ## TL;DR ### Why use Composio over default connectors? - Apps with read and write access. Default connectors mostly can read your data. Composio's Octagon integration lets ChatGPT Work take actions like creating drafts, sending updates, labeling records, and more. - 1,500+ 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 Octagon MCP to ChatGPT Work ### Prerequisites - A ChatGPT account with access to ChatGPT Work (rolling out across Pro, Enterprise, Edu, Plus, and Business plans). We will use the [ChatGPT desktop app](https://openai.com/chatgpt/download/), which is available on every plan. - Access to the Octagon 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.

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