# Connect ChatGPT to Social Media with RobinReach (2026 Setup) > To connect ChatGPT to your social media, add RobinReach as a custom MCP server. In ChatGPT on the web, open Plugins, click +, choose Add custom MCP server, name it RobinReach, paste https://robinreach.com/mcp/v1/messages and set authentication to OAuth. Create it, sign in to RobinReach, then type @ in a chat and pick RobinReach. ChatGPT can then write, schedule and publish posts on 13 networks, answer comments and read your analytics, and it asks before anything that changes your account. You need a paid ChatGPT plan, and on the RobinReach side the Bloom, Thrive and Scale plan. Canonical: https://robinreach.com/ai/integrations/chatgpt App: ChatGPT, by OpenAI (https://chatgpt.com) Where you use it: Web Sign in: Sign in with RobinReach. Setup time: 2 minutes. RobinReach plan: Bloom, Thrive and Scale. ## What you need In ChatGPT: - ChatGPT on the web. Custom MCP servers are added on the web, not in the mobile apps. - A paid ChatGPT plan. On Business, Enterprise and Edu workspaces, admins decide who may add custom MCP servers. In RobinReach: - The Bloom, Thrive and Scale plan (Bloom, $24 a month). - To sign in: the account owner, an account admin or a brand admin. Anyone else can use an API key. ## Setup ### 1. Copy the RobinReach URL The same address works for every account. Your login decides which brands ChatGPT can reach. ``` https://robinreach.com/mcp/v1/messages ``` ### 2. Add a custom MCP server In ChatGPT on the web, open **Plugins**, click the **+** button and choose **Add custom MCP server**. ### 3. Fill it in Name it **RobinReach** and paste the URL under Connection. Set authentication to **OAuth**, tick **I understand and want to continue** and click **Create as a plugin**. ### 4. Sign in to RobinReach A RobinReach window opens. Sign in, keep your account selected or pick a single brand, and click **Connect**. Connecting needs the account owner, an account admin or a brand admin. Install the plugin if ChatGPT asks. ### 5. Use it in a chat Start a new chat, type **@** and pick RobinReach, then ask it to list your RobinReach brands. Pick it again with @ when a later message needs it. Check it works: Type @, pick RobinReach and ask: "List my RobinReach brands". ### Prefer an API key? In step 3, paste this URL with the key from the Integrations page in RobinReach and set authentication to No authentication. The URL contains your key, so keep it private. ``` https://robinreach.com/mcp/v1/messages?api_key=YOUR_API_KEY ``` ## Things to ask ChatGPT - Write three LinkedIn posts from this blog post and schedule them for Tuesday, Wednesday and Thursday at 9. - Make a bright image for Friday's sale and add it to a draft for Instagram and Facebook. - How did yesterday's post do on each network? - Fill any empty days in the next two weeks with drafts that match our content pillars. - Reply to new Instagram comments in our voice, and show me the replies before you send them. ## Troubleshooting **I do not see Plugins or Add custom MCP server.** On Business, Enterprise and Edu workspaces an admin has to allow it (the Create plugins with MCPs permission). Some personal accounts still show the older route, Settings, then Apps, then Advanced settings, where you turn on Developer mode and click Create. **ChatGPT asks me to confirm every change.** That is on purpose. ChatGPT confirms actions that write, and RobinReach labels its read only tools so those run without a prompt. You can let ChatGPT remember your choice for the rest of a conversation. **ChatGPT stopped using RobinReach mid chat.** ChatGPT applies a plugin to the message where you pick it. Type @ and pick RobinReach again when you ask for something new. **A tool fails after RobinReach adds new features.** Workspace plugins keep a snapshot of the tool list. An admin can refresh the plugin in the workspace settings to pick up the new tools. **Can I set it up from the ChatGPT app on my phone?.** No. Add the server in ChatGPT on the web. OpenAI does not support connecting custom MCP servers on mobile. ## Video [I Connected ChatGPT To My Social Accounts (Full Setup, 2 Minutes)](https://www.youtube.com/watch?v=-ln8WC8Q5xs) (5:42) ## Other AI apps - [Connect Claude to RobinReach](https://robinreach.com/ai/integrations/claude.md) - [Connect Codex to RobinReach](https://robinreach.com/ai/integrations/codex.md) - [Connect n8n to RobinReach](https://robinreach.com/ai/integrations/n8n.md) ## Questions ### Do I still need Developer mode in ChatGPT? Not in the current Plugins setup, where you add the server directly and accept a risk notice. Some accounts still show the older Developer mode route; the steps there are listed under fixes. ### Does it work with a free ChatGPT account? No. Adding custom MCP servers needs a paid ChatGPT plan, and on work workspaces your admin may need to allow it. ### Will ChatGPT publish without asking? ChatGPT asks before actions that change things, and RobinReach marks publishing right away, deleting and client links so ChatGPT confirms them with you. Reading your calendar or analytics runs without a prompt. ### Do I need an API key for ChatGPT? No. You sign in with your RobinReach login. The API key URL is a fallback for people who are not admins. ### Is ChatGPT or Claude better for RobinReach? Both get the same 77 tools. Claude also works in its desktop and mobile apps once added on the web; ChatGPT is set up on the web. Pick the one your team already uses. ## Sources Last checked on 24 October 2026.
