# Astro Adapter
This adapter generates a search index from your Astro content collections. It runs automatically at build time.
See the [main README](../../README.md) for deployment instructions.
## Installation
1. Install the `glob` dependency:
```bash
bun add glob
```
2. Copy `search-index.mjs` to `src/integrations/` in your Astro project.
## Usage
```javascript
// astro.config.mjs
import { defineConfig } from 'astro/config';
import { searchIndexIntegration } from './src/integrations/search-index.mjs';
export default defineConfig({
integrations: [
searchIndexIntegration({
siteName: 'My Blog',
siteDomain: 'blog.example.com',
siteDescription: 'A blog about things',
toolPrefix: 'myblog',
contentDir: 'src/content/posts',
}),
],
});
```
## Options
| Option | Default | Description |
|--------|---------|-------------|
| `siteName` | `My Website` | Site name |
| `siteDomain` | `example.com` | Site domain |
| `siteDescription` | (empty) | Site description |
| `toolPrefix` | `website` | Tool name prefix |
| `contentDir` | `src/content` | Content directory |
| `outputFile` | `dist/mcp-search-index.json` | Output path |
| `excludeSlugs` | `[]` | Slugs to exclude |
| `staticPages` | `[]` | Additional pages to include |
## Static Pages
To include pages that aren't in content collections (like `/about`):
```javascript
searchIndexIntegration({
// ...
staticPages: [
{
url: '/about',
title: 'About Us',
abstract: 'Learn about our company',
file: 'src/pages/about.md', // Optional: read content from file
},
],
});
```
## Output
After `bun run build`, the index is at `dist/mcp-search-index.json`.
Upload to R2:
```bash
npx wrangler r2 object put my-site-mcp-data/search-index.json \
--file=dist/mcp-search-index.json \
--content-type=application/json
```
