ChatGPT Social Media Connector Setup
ChatGPT reaches social media through a custom MCP server added in Developer mode, authenticated over OAuth. Blotato serves a complete OAuth 2.1 stack, including protected-resource metadata, dynamic client registration, and PKCE, which is exactly what Developer mode expects. The real constraint is on the ChatGPT side: Developer mode is web only, and it appears on Pro, Plus, Business, Enterprise, and Education accounts. GPT-6 Astra connects the same way, through Developer mode in a regular chat.

How to connect ChatGPT to social media
- Connect your social accounts in Blotato.
- Open ChatGPT on the web, go to Settings then Security and login, and enable Developer mode. It is not available in the mobile or desktop apps.
- Open Settings, then Plugins, and add a new plugin pointing at https://mcp.blotato.com/mcp. If a walkthrough tells you to look under Connectors, it predates July 2026, when OpenAI moved that menu into Plugins.
- Complete the OAuth approval while logged into Blotato in the same browser.

How do I know it worked?
Ask ChatGPT to list your connected accounts. It calls
blotato_list_accounts and returns your platforms, which confirms both the connection and
the authentication in one step. If you see your accounts, setup is done.
What social media accounts do I have connected?
Worth knowing before you rely on it: analytics prompts return data for every platform except LinkedIn, which publishes normally but reports no metrics yet.
What to ask ChatGPT once it is connected
- Post this to Instagram.
- ChatGPT calls blotato_list_accounts, then blotato_create_post with the image and caption from the chat. The draft and the publish happen in the same window, which is the entire reason to connect it here rather than copying into another tab.
- Make this into a Reel instead.
- The same call with mediaType set to reel. Facebook video has to be a reel too, since regular feed video is no longer supported there.
- Reply to the comments on my last Instagram post.
- blotato_list_comments reads them and blotato_post_comment replies. Instagram and Facebook are the only platforms with comment access, so the same request against a LinkedIn post has nothing to read.
- When someone comments 'price' on my Instagram post, DM them the link.
- blotato_create_automation builds it: a comment-received trigger, the keyword price, and the message to send. Instagram and Facebook Pages only, and it is reply-only, so it answers people who comment or message you first and never opens a conversation on its own.
What breaks, and how to fix it
The usual dead end is looking for the connector option in the ChatGPT desktop or mobile app, where Developer mode does not exist. It is web only. The second is trying to authenticate with an API key header, which Developer mode does not accept: it takes OAuth, No Auth, or Mixed, and no custom headers, so the API key path that works in Cursor or Codex has no equivalent here. The third is following a walkthrough written before July 2026, when OpenAI moved connectors into the Plugins directory and the old Connectors menu stopped matching what is on screen.
What is different about ChatGPT
ChatGPT is the one agent on this list where the limiting factor is entirely the vendor account tier rather than the connection. If you are in the OpenAI ecosystem and Developer mode is not available to you, OpenAI Codex is a different OpenAI product that takes the same endpoint with a plain API key header and no tier requirement. On the model side, GPT-6 Astra is built for computer use and multi-step work, which changes how much it can prepare before the publish call rather than how that call happens. Note that agent mode does not use custom MCP plugins, so this runs from a regular chat.
