# AI Development

> Use Lunar documentation with AI tools like Claude, ChatGPT, Cursor, and VS Code

Lunar's documentation is designed to work seamlessly with AI-powered development tools. Whether using an AI assistant to generate storefront code or querying the docs from an IDE, several built-in features make this possible.

## llms.txt

The Lunar documentation site automatically provides an `llms.txt` file at the root of the docs domain. Similar to how `sitemap.xml` helps search engines index a website, `llms.txt` helps large language models discover and understand documentation content.

Two files are available:

| File            | URL                                                                        | Description                                       |
| --------------- | -------------------------------------------------------------------------- | ------------------------------------------------- |
| `llms.txt`      | [docs.lunarphp.com/llms.txt](https://docs.lunarphp.com/llms.txt)           | Structured listing of all pages with descriptions |
| `llms-full.txt` | [docs.lunarphp.com/llms-full.txt](https://docs.lunarphp.com/llms-full.txt) | Full documentation content in a single file       |

The `llms.txt` file lists every documentation page along with its description, making it useful for AI tools that need to locate specific topics. The `llms-full.txt` file consolidates all documentation into one file, which is ideal for AI tools that benefit from ingesting the entire knowledge base at once.

<Tip>When pasting documentation context into an AI chat, use `llms-full.txt` to give the model comprehensive knowledge of Lunar's API and features.</Tip>

## MCP Server

Lunar's documentation includes a built-in [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server. MCP allows AI applications to search and retrieve documentation directly, providing more accurate and up-to-date responses than relying on the model's training data alone.

The MCP server is available at:

```
https://docs.lunarphp.com/mcp
```

### Connecting from AI Tools

<Info>The MCP server supports filtering by documentation version using a `version` parameter (e.g., `v1.x` or `v0.x`).</Info>

#### Claude Code

```bash theme={null}
claude mcp add lunar-docs --transport http https://docs.lunarphp.com/mcp
```

#### Cursor

Open the Command Palette and select **MCP: Add Server**, then add the following to the MCP configuration:

```json theme={null}
{
  "mcpServers": {
    "lunar-docs": {
      "url": "https://docs.lunarphp.com/mcp"
    }
  }
}
```

#### VS Code

Create or update `.vscode/mcp.json` in the project root:

```json theme={null}
{
  "servers": {
    "lunar-docs": {
      "type": "http",
      "url": "https://docs.lunarphp.com/mcp"
    }
  }
}
```

#### Claude (Web)

Navigate to **Settings > Connectors > Add custom connector**, then enter a name and the MCP server URL.

## Markdown Export

Any documentation page can be viewed as plain Markdown by appending `.md` to its URL. For example:

```
https://docs.lunarphp.com/1.x/reference/carts.md
```

This is useful for feeding specific pages into AI tools as context. Markdown is more token-efficient than HTML, resulting in faster processing and better response quality.

## Contextual Menu

Each documentation page includes a contextual menu that provides quick access to AI-related actions:

* **Copy as Markdown** for pasting into any AI tool
* **Open in Claude**, **ChatGPT**, or **Perplexity** with the current page loaded as context
* **Install MCP server** directly into Cursor or VS Code
