Fix a Claude Code or Codex connection

Use a supported client

Use Claude Code or Codex with the MotionUI tools connected. Ordinary ChatGPT and Claude chats are not supported clients for this MotionUI workflow. If you use Claude Code inside the Claude desktop app, choose the Code environment.

Tools are missing

1. Install the panel from the After Effects tab in MotionUI.

2. Open AI → Connect AI in the desktop app. Connect or update the chosen agent.

3. Resolve any missing-app or Node.js message.

4. Start a new Claude Code or Codex session after changing the connection.

The composition is unavailable

Open After Effects, the MotionUI panel and the intended composition. Check the After Effects connection in the desktop app, then request a read-only inspection. Compare the returned names with your timeline.

The agent does not open or sign in

Open the selected coding agent directly and complete sign-in there. If the panel reports a copied prompt, paste it into that session when the application link fails.

Figma is unavailable

Run the MotionUI plugin in the target Figma file and confirm that it appears under Linked files. Keep the plugin open. Figma access is separate from the After Effects tool connection.

Ask for help

Include your operating system, MotionUI and panel versions, the chosen agent and the exact error. Do not send passwords, API keys or authentication tokens.
