Cursor Setup

Use the marketplace as your AI backend in Cursor.

Configuration

  1. Open Cursor Settings → Models
  2. Add a custom model:
    • API Base URL: https://api.surplusintelligence.ai/v1
    • API Key: inf_your_key_here (get from the Buy page)
    • Model: claude-opus-4.6 (or any model from /v1/models)

Tool Compatibility

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.
