Apple Music plugin advertises write actions but returns “Unknown tool”

ChatGPT Bugs

I’m using ChatGPT Plus on the web and have connected and signed in to the Apple Music plugin.

The plugin details page advertises the following write actions:

  • Add to Your Apple Music Favorites
  • Add to Your Apple Music Library
  • Create an Apple Music Playlist
  • Sign In to Apple

However, after explicitly attaching @Apple Music to the conversation and requesting a playlist test, the plugin calls failed with:

MCP error: -32001: Unknown tool ({“name”:“apple_music.search”})

and:

MCP error: -32001: Unknown tool ({“name”:“apple_music.get-track-details-batch”})

Steps to reproduce:

  1. Open the Apple Music plugin details page and verify that the write actions are listed.
  2. Complete “Sign In to Apple.”
  3. Start or refresh a ChatGPT conversation.
  4. Explicitly attach @Apple Music.
  5. Ask ChatGPT to create an Apple Music playlist from two valid song IDs.
  6. The connector returns “Unknown tool.”

Expected behavior:

The tools declared on the plugin details page should be discoverable and callable after Apple authentication, particularly “Create an Apple Music Playlist.”

Actual behavior:

The plugin advertises write capabilities, but its MCP backend does not recognize even the Apple Music search and track-detail tools.

Plugin/app identifier:
app-6938a94a61d881918ef32cb999ff937c

This appears to be a plugin manifest/tool-registry or deployment-version mismatch rather than an Apple authorization failure. Please route this report to the ChatGPT plugins/connectors team.

I can provide the conversation URL and screenshot showing the advertised write actions.

Hey @Dai123, thanks for flagging this and sharing the errors and steps you’ve already tried.

Are you still getting “Unknown tool” with Apple Music? If so, please add the affected conversation URL, your selected model, the date and time of a recent failure, and redacted screenshots showing the error and advertised actions to your existing private Support request. If you don’t have one, please email support@openai.com.

Please keep conversation links and private details in that request.
