Canonical OpenAI function toolwhat the seller receives

Non-function toolsno function equivalent, so they are dropped

Whatever shape Cursor sends is converted to one canonical function tool before a seller sees it.

Cursor sends tools in non-standard formats. The marketplace normalizes all of them automatically:

Cursor's computer_20241022, text_editor_20241022, bash_20241022 → stripped (non-function tools)
Tools without a type field → type: "function" added
Anthropic-native tools → converted to OpenAI format

You don't need to do anything - it just works.
