ChatGPT Social Media Connector Setup

ChatGPT reaches social media through a custom MCP server added from ChatGPT Plugins, authenticated over OAuth. Blotato serves a complete OAuth 2.1 stack, including protected-resource metadata, dynamic client registration, and PKCE. The real constraint is on the ChatGPT side: custom MCP servers are added on the web, not in the mobile app, and OpenAI's help center lists the write actions that publishing needs on Business, Enterprise, and Edu, leaving Pro with read and fetch. GPT-6 Astra connects the same way, through the same plugin in a regular chat.

How to connect ChatGPT to social media

Connect your social accounts in Blotato.
Open ChatGPT on the web, since a custom MCP server cannot be added from the mobile app. On a Business workspace, only an admin or owner can add it.
Go to ChatGPT Plugins, select the plus button, then Add custom MCP server. Name it Blotato, enter https://mcp.blotato.com/mcp, choose OAuth, check I understand and want to continue on the risk warning, and select Create as a plugin.
Complete the OAuth approval while logged into Blotato in the same browser.

Custom MCP server URL (OAuth)

https://mcp.blotato.com/mcp

Custom MCP servers in ChatGPT are added from Plugins on the web, with no Developer mode step. OpenAI’s help center lists write actions, which publishing needs, on Business, Enterprise, and Edu, and gives Pro read and fetch actions. It connects over OAuth rather than an API-key header, which is how Blotato authenticates Claude too.

Blotato added as a custom connector at mcp.blotato.com/mcp, with its social media tools listed — Blotato as a custom connector, with its tool permissions listed. This is the screen ChatGPT shows once the OAuth approval completes.

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.

First prompt to run

What social media accounts do I have connected?

An AI agent answering "what social accounts do i have connected?" by calling Blotato and listing 10 connected social media accounts across Twitter, Bluesky, Instagram, Threads, LinkedIn, Facebook, YouTube, Pinterest, and TikTok — The reply you are looking for: the agent calls Blotato and lists every connected account. Here it returns 10 accounts across all nine platforms.

Worth knowing before you rely on it: when an agent ranks your best posts through MCP, metrics cover X, Instagram, Facebook, Threads, and Bluesky. TikTok, YouTube, and Pinterest analytics are available in the Blotato web app and REST API, and LinkedIn 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 an older walkthrough that starts by turning on Developer mode or sends you to a Connectors menu. OpenAI's help center now says you do not need Developer mode first, so go straight to Plugins. If the plus button there offers no Add custom MCP server option, your plan or workspace permissions are the likely limit. The second is looking for the option in the ChatGPT mobile app, since custom MCP servers are added on the web. The third is pasting an API key header config copied from a Cursor or Codex guide. Use OAuth here, the path this page documents for ChatGPT.

What is different about ChatGPT

ChatGPT is the one agent on this list where the limiting factor is the ChatGPT plan and workspace permissions rather than the connection. If you are in the OpenAI ecosystem and your plan cannot add a custom MCP server, 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. ChatGPT Dots, OpenAI's always-on agent, draws on the same Plugins menu, so if a custom plugin reaches a dot, the same plan rules apply to it.

Vendor documentation: ChatGPT MCP setup. The handshake it uses is the MCP authorization spec, which Blotato implements in full, including dynamic client registration and PKCE.

FAQ

ChatGPT social media FAQs

01 Can ChatGPT post to social media?

Yes. ChatGPT cannot reach a social account on its own, because it has no platform credentials. Connecting it to Blotato's hosted MCP server at https://mcp.blotato.com/mcp gives it tools to publish and schedule across nine platforms: X, LinkedIn, Facebook, Instagram, TikTok, YouTube, Threads, Bluesky, and Pinterest. ChatGPT authenticates with OAuth only.

02 How do I connect ChatGPT to social media?

03 How do I set up ChatGPT for social media?

Setting up ChatGPT for social media takes one connection. Connect your social accounts in Blotato, then give ChatGPT the hosted MCP endpoint https://mcp.blotato.com/mcp and authenticate with OAuth only. What ChatGPT takes: Custom MCP server URL (OAuth). Once it loads, ChatGPT can publish and schedule to X, LinkedIn, Facebook, Instagram, TikTok, YouTube, Threads, Bluesky, and Pinterest from a plain-language prompt.

04 What is the best way to manage social media with ChatGPT?

Let ChatGPT do the drafting and decision making, and let a publishing layer hold the accounts and the schedule. The thing that makes this work on ChatGPT in particular: ChatGPT is the one agent on this list where the limiting factor is the ChatGPT plan and workspace permissions rather than the connection. If you are in the OpenAI ecosystem and your plan cannot add a custom MCP server, 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. ChatGPT Dots, OpenAI's always-on agent, draws on the same Plugins menu, so if a custom plugin reaches a dot, the same plan rules apply to it.

05 What goes wrong when connecting ChatGPT?

06 Does ChatGPT need to be running for a scheduled post to go out?

No. Scheduling runs on Blotato rather than inside ChatGPT. Once the agent queues a post, it publishes at the scheduled time whether or not ChatGPT or your computer is on. This is the practical difference between an agent that drafts and a system that runs unattended.

07 What can I ask ChatGPT to do 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.

08 How much does it cost to connect ChatGPT?

Starter is $29/mo flat for 20 connected accounts, and the price does not scale with posting volume. API and MCP access is not part of the 7-day trial: generating a key activates the paid Starter plan, so plan on subscribing rather than trialing it.

Connecting a different agent?

Same endpoint, same accounts, one setup per client. The AI agents for social media hub covers what all of them share, including every tool your agent can call.
