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)

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.
