How Sign-In Works
The Mallary plugin uses OAuth. ChatGPT 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.Your Requests Control What Happens
Mallary only posts, uploads, or replies when you ask for that result. These actions are real. A post can go live on your social accounts. Check the profile, platforms, message, image, and time before you ask ChatGPT to post.Make an Image and Post It
You can ask ChatGPT to make an image and post it with Mallary. You can also choose an image in ChatGPT. ChatGPT sends Mallary a short-lived link to the image you approved. Mallary checks the image, copies it tohttps://files.mallary.ai, and uses that Mallary link in your post. Mallary accepts JPEG, PNG, WebP, and GIF images up to 25 MB through this flow.
This image tool is only for social post images. Do not use it for private customer files, health records, ID records, card details, passwords, API keys, or access tokens.
ChatGPT Plugin and Codex

Video attachments (next plugin version)
Mallary’s current ChatGPT plugin does not support video uploads yet. Video support is built for a future plugin update. It needs OpenAI review and publication before it can be used in the current plugin. We do not have a confirmed release date. The next version will accept attached MP4 and MOV videos up to 512 MB. Mallary will copy the file to its CDN on the server. You will not need to add*.r2.cloudflarestorage.com to an allowed-domain list.
ChatGPT must make the video attachment available to the plugin. File support may vary by ChatGPT account and client.
For now, use ChatGPT to write the caption, then upload and post the video in the Mallary dashboard. A client that can read your video file and send HTTP PUT requests can also use standard MCP’s video upload flow.
Each social platform has its own video rules. LinkedIn requires MP4. Reddit does not support video uploads through Mallary. Mallary checks your selected destinations before posting and reports any problems.
