# Install on Cursor / Windsurf

> Add Arrays Skills as project rules so Cursor and Windsurf use them automatically.

## 1. Clone the Skills repo

```bash theme={null}
git clone https://github.com/ArraysData/arrays-skills.git
```

## 2. Reference Skills from your project

Cursor and Windsurf both read project-level rules. In your repo root, create `.cursor/rules/arrays.mdc` (Cursor) or `.windsurfrules` (Windsurf):

<Tabs>
  <Tab title="Cursor (.cursor/rules/arrays.mdc)">
    ```markdown theme={null}
    ---
    description: Use Arrays Skills for financial-data questions
    globs: ["**/*"]
    ---

    When the user asks about stocks, crypto, ETF, macro, or any market data,
    follow the Arrays Skills at /absolute/path/to/arrays-skills/skills/.

    Authentication:
    - Base URL: https://data-tools.prd.arrays.org/api
    - Header: X-API-Key from ARRAYS_API_KEY env var
    ```
  </Tab>

  <Tab title="Windsurf (.windsurfrules)">
    ```markdown theme={null}
    # Arrays Financial Data

    Use the Arrays Skills at /absolute/path/to/arrays-skills/skills/
    when answering questions about market data.

    Auth: X-API-Key header, key in ARRAYS_API_KEY env var.
    Base: https://data-tools.prd.arrays.org/api
    ```
  </Tab>
</Tabs>

## 3. Set your API key

In your project's `.env` (and add `.env` to `.gitignore`):

```bash theme={null}
ARRAYS_API_KEY=your_key_here
ARRAYS_API_BASE_URL=https://data-tools.prd.arrays.org/api
```

## 4. Try it

In Cursor / Windsurf chat, ask:

```
Show me NVDA's last 4 quarters of free cash flow.
```

The agent should follow the Arrays Skill, call `company/cashflow-statements`, and return real data.

<Info>
  Cursor and Windsurf currently can't auto-execute HTTP calls — they'll generate the code, and you run it. For a fully automated loop, use [Claude Code](/skills/install-claude-code) or [Codex](/skills/install-codex).
