How to connect Linkedin MCP with ChatGPT

ChatGPT can take action across your apps and files, stay with a project for hours, and turn 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 Linkedin account to ChatGPT via Composio Connect, so it can share a new post about our product launch, delete your last published linkedin post, fetch company pages i can manage through natural language commands without ever putting your account credentials at risk.

Why use Composio over default connectors?

• Apps with read and write access. Default connectors mostly can read your data. Composio's Linkedin integration lets ChatGPT 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.

Prerequisites

• A ChatGPT account. We will use the ChatGPT desktop app, and the steps are the same on the web.
• Access to the Linkedin workspace you want to connect.
• Composio plugin.

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.
