Mallary connects your social publishing workflow to ChatGPT and Codex. You can work with your connected social accounts without sharing an API key.
The Mallary plugin for ChatGPT and Codex is under review by OpenAI. It will appear in the shared plugin directory after approval. Approved testers can still connect it in ChatGPT Developer Mode.

​
What You Can Do

  • see connected social accounts
  • create or schedule social posts
  • use a different message for each platform
  • check publishing status and open published posts
  • read comments and post approved replies
  • review post analytics
  • manage Mallary profiles, settings, and webhooks

​
How Sign-In Works

The Mallary plugin uses OAuth. ChatGPT or Codex opens Mallary in your browser and asks you to approve access. Mallary never gives the plugin your password, social account tokens, API keys, or payment details. You can review or revoke access from your Mallary account at any time.

​
Safe Actions

The plugin checks read-only information first. Before it publishes, replies, deletes, disconnects an account, changes settings, or creates a webhook, it shows the exact action and asks for confirmation. Do not approve an action until the profile, platforms, message, schedule, and other details are correct.

​
Media In Version 1

The first version supports text posts and media that is already hosted at https://files.mallary.ai. ChatGPT cannot upload bytes from a local file directly through the Mallary plugin in version 1. Creating an upload URL does not upload the file.

​
Availability

The plugin is not publicly listed yet. OpenAI is reviewing it now. Mallary MCP endpoint:
