How to connect ChatGPT with Publer’s MCP

Once connected, you can use ChatGPT to create and schedule posts, get content suggestions, and manage your social media directly from ChatGPT Web or the Codex CLI.


To learn more about Publer's MCP and how it works, check out this guide.


Note: Publer's MCP integration is available on the Business and Enterprise plans.


To connect ChatGPT with Publer:


  • Go to Settings in Publer.
  • Select AI & Automations.



  • Under AI & MCP, click on ChatGPT.



You can connect Publer with either ChatGPT Web or the Codex CLI.


ChatGPT Web


To connect Publer with ChatGPT on the web:


  • Select the ChatGPT Web tab.



  • Under Get your API key, paste an existing Publer API key or click Create an API key.



  • If you create a new API key, give it a name and choose the permissions you want to grant.
  • Generate the API key and copy it. Then, click Done, and the API key will be pasted automatically.


Keep your API key private and do not share it with anyone who should not have access to your Publer account.


Once the API key is added, continue with the setup instructions provided by Publer.


  • Open ChatGPT and go to Settings. Alternatively, you can click on ChatGPT settings.



  • It will send you to the Security and login section.
  • Under Advanced settings, enable Developer mode.



  • You can now go back to Publer and continue with the instructions to Add new app.
  • Publer will provide the information you need to add the MCP app to ChatGPT, including the Name, MCP Server URL, and Authentication method.



  • Click Add > Create MCP App.



  • In ChatGPT, enter Publer as the name.
  • Under Connection, select Server URL.
  • Paste the MCP Server URL provided by Publer.
  • Under Authentication, make sure to select the No sign-in/No authentication option.


Important: Under Authentication, make sure to select the No sign-in/No authentication option when connecting Publer. The MCP Server URL provided by Publer already includes the API key required for authentication, so you don't need to use OAuth or sign in separately through ChatGPT.


  • Confirm that you understand the risks of connecting a custom MCP server, then click Create to finish.



  • Publer will now be connected to ChatGPT.
  • You can find the plugin you created under Plugins. Click on it to open it.



  • From there, click on Try in chat to start using Publer directly from ChatGPT.



  • You can then enter a prompt describing what you want Publer to do. For example: "Check the statistics for my [social account] for this quarter."
  • ChatGPT will use the Publer plugin to help complete the request.



  • You can also give ChatGPT more detailed instructions. For example, you can say something like "Create a post about [topic] for my [social account]. Access my Publer Media Library and use a relevant image for the post."



Codex CLI


You can also connect Publer with the Codex CLI.


  • Go to Settings > AI & Automations > ChatGPT in Publer.
  • Select the Codex CLI tab.



  • Paste an existing Publer API key or click Create an API key.





  • After entering your API key, Publer will provide the command required to add the Publer MCP server.
  • Copy the command and run it in your terminal.



Once added, you can start using Codex with your Publer workspace.


What can you do with ChatGPT and Publer?


Once connected, you can manage your account directly from ChatGPT.


For example, you can ask ChatGPT to:


  • Create posts, drafts, and content ideas, with text, images, videos, links, carousels, polls, Reels, Stories, and other supported post types.
  • Schedule, AutoSchedule, publish, recycle, or set up recurring posts for one or multiple social accounts.
  • Upload and use media from your Publer Media Library or files shared directly in ChatGPT.
  • Add post options such as first comments, follow-up comments, AutoShare, watermarks, signatures, locations, labels, albums, and Pinterest boards.
  • View and manage your connected social accounts, workspaces, scheduled posts, drafts, published posts, and media.
  • Edit or delete supported posts and manage existing Publer content.
  • Check analytics, analyze recent performance, and view competitor data where supported.
  • Generate content ideas, captions, and publishing suggestions before creating or scheduling your posts.


For example:


Create a LinkedIn post about our latest product update, add this image, and save it as a draft in Publer.


Or:


Create 5 Instagram posts and AutoSchedule them for next week.


Or:


Show me my recent Facebook performance and suggest content ideas based on the results.


ChatGPT will use Publer's MCP tools to complete the request based on the permissions available to your account and the features supported by each social network.


Keep in mind


  • When connecting Publer with ChatGPT Web, make sure to select the No sign-in/No authentication option under Authentication.
  • Publer uses the API key included in the MCP Server URL for authentication, so you don't need to configure OAuth or a separate sign-in method in ChatGPT.
  • ChatGPT can only perform actions supported by Publer's MCP.
  • The same social network requirements and limitations that apply in Publer also apply when using ChatGPT.
  • Keep your Publer API key and MCP Server URL secure.
  • Always review the social account, content, and scheduling details before publishing important posts.
  • You can manage or revoke your API keys at any time from Settings > API & Webhooks.
