Use PostDaily in Codex

PostDaily's plugin for Codex adds the server plus skills for uploading files from your computer and turning a release into posts. Codex asks you before every call that can publish, schedule, delete or cancel a post. The same setup works in the Codex CLI and the Codex IDE extension.

Install the plugin

1. 1
   Add PostDaily's plugin marketplace

   In your terminal, run codex plugin marketplace add mehedihasan2810/postdaily-codex-plugin

2. 2
   Install the plugin

   Run codex plugin add postdaily@postdaily

3. 3
   Sign in

   Run codex mcp login postdaily. PostDaily opens in your browser: choose what Codex can do and which workspaces it can use, then select Allow access.

Or add only the server

Run codex mcp add postdaily --url https://mcp.postdaily.app/mcp, then codex mcp login postdaily. You get the same tools without the skills.

Things to ask

• "Summarise this week's merged pull requests as a short post for Bluesky and Threads, and put it in my queue."
• "Upload the screenshot in assets/launch.png and draft an Instagram post with it."
• "Which of my posts failed this week, and why?"

Disconnect

In PostDaily, open Settings → AI agents and select Disconnect next to Codex. It stops working on its next request.
