Slate MCP now works with Codex

ReleaseNewsSlate Builder

Codex Desktop is now an officially supported Slate MCP client. If you use OpenAI's Codex app, you can connect it to Slate in about two minutes and start managing your eLearning course library through conversation, the same way creators on Claude Desktop, Claude.ai, and Claude Code have been doing since February.

Codex Desktop calling Slate MCP tools — get account stats, list courses, get course summary, list preview links, preview course outline — to audit a course library and plan a new course

What you can do from Codex

Slate MCP is available on Standard and Pro. Standard creators get the core authoring and library tools; Pro adds review cycles, Share & Track, tag management, and account-wide discovery on top. From inside Codex Desktop, you can:

  • Draft a course from a prompt: Tell Codex who the course is for, how long it should run, and what source material to start from. It sketches an outline first so you can review it, then generates the full draft in your chosen language (one of 15 supported), grounded in Gagné's Nine Events of Instruction and Mayer's Multimedia Principles.
  • Manage your library through conversation: List, search, and filter courses. Ask for a summary of any course by name. Open it in the Slate editor with a direct link.
  • Run review cycles: Open a review, generate AI summaries of stakeholder feedback, and turn comments into an actionable checklist. (Pro)
  • Track learner engagement: Create Share & Track links, check completion rates, and see who is engaging with which course. (Pro)
  • Look up docs and the LESSON.md format: Codex can search the official Slate documentation and the open LESSON.md authoring format on its own, so it can hand back content that imports straight into Slate.

A full list of tools, with which ones are Standard versus Pro, lives on the Slate MCP page.

Why this matters

Slate is built around supporting a broad range of workflows and providers. A course can start from a Canva presentation, a PowerPoint deck, a blank page, or a conversation with the AI tools you already have open. Once it's in Slate, the same flexibility applies to how you manage it: connect Claude or Codex through MCP to draft, review, tag, and share courses without changing tools.

Setup is two minutes

Open Codex Desktop, go to Settings › MCP Servers › Add Server, name it Slate, choose Streamable HTTP, and paste https://mcp.slatebuilder.io/mcp. Codex opens a browser window for you to sign in, and stays connected after that. Step-by-step screenshots are on the Codex Desktop setup tab.

What's next

A dedicated Slate listing in the ChatGPT app marketplace is up next, so teams who do not run the Codex app can connect Slate in a click rather than going through manual setup. The current client roadmap lives on the MCP page, and we keep the product roadmap updated as items ship.

If you are already on Standard or Pro, the new Codex tab is live now in setup instructions. New to Slate? Sign up free and try the MCP connector as soon as you upgrade.
