Connecting Postpone to ChatGPT

Connect Postpone to ChatGPT or the Codex CLI to create and schedule social media posts using natural language.

ChatGPT lets you manage your Postpone content using natural language. Once connected, you can create and schedule posts, get content suggestions, and manage your social media directly from ChatGPT or the Codex CLI.

Connecting ChatGPT Web

ChatGPT connects to Postpone over OAuth. Adding a custom app requires enabling Developer mode first.

Open ChatGPT

Open ChatGPT in your browser.

Enable Developer mode

Open Settings, find the Apps section, then toggle on Developer mode under Advanced settings.

Add a new app

Add a new app and fill in the form with:

  • Name: Postpone
  • MCP Server URL: https://api.postpone.app/mcp
  • Authentication: OAuth

Create and approve access

Click Create. A Postpone sign-in window will open — approve access to complete the connection.

Finish the setup

Back in ChatGPT, click the Refresh button next to Information to fetch Postpone's tools.

Connecting the Codex CLI

If you use the Codex CLI, add Postpone as an MCP server in your Codex configuration using the same MCP server URL:

https://api.postpone.app/mcp

Try It Out

Once connected, ask ChatGPT something like:

"List all my connected Postpone social accounts."

"Schedule a post for my LinkedIn account announcing our new feature, set for 9am tomorrow."

"Show me my published posts from last week and how many likes and comments they got."
