## 🚀 Quick Start
### Install via Smithery (Recommended)
The easiest way to install this MCP server is through [Smithery](https://smithery.ai/server/@CaullenOmdahl/tailwind-svelte-assistant):
```bash
npx -y @smithery/cli install @CaullenOmdahl/tailwind-svelte-assistant --client claude
```
This will automatically:
- Install the server
- Configure it for Claude Desktop
- Set up all required dependencies
### Install via Direct URL
For other MCP clients, use the direct server URL:
```
https://server.smithery.ai/@CaullenOmdahl/tailwind-svelte-assistant/mcp
```
Add this to your MCP client configuration:
```json
{
"mcpServers": {
"tailwind-svelte-assistant": {
"url": "https://server.smithery.ai/@CaullenOmdahl/tailwind-svelte-assistant/mcp",
"transport": "http"
}
}
}
```
## 🛠️ Manual Installation & Setup
### Prerequisites
- **Node.js 20+** (required for ES modules support and dependencies)
- npm or yarn
- Git (for cloning repository)
### Install Dependencies
```bash
npm install
```
### Build the Server
```bash
npm run build
```
### Development Mode
```bash
npm run watch
```
## 🔧 Configuration
The server uses secure defaults but can be configured via the `ServerConfig` interface:
```typescript
const CONFIG: ServerConfig = {
maxFileSize: 3 * 1024 * 1024, // 3MB max file size (for full docs)
cacheTimeout: 5 * 60 * 1000, // 5 minutes cache timeout
contentBasePath: './content',
svelteFullDocsPath: './content/docs/svelte-sveltekit-full.txt',
tailwindFullDocsPath: './content/docs/tailwind-docs-full.txt',
// ... other paths
};
```
### Documentation Updates
Documentation is automatically downloaded and updated:
```bash
# Update all documentation (Svelte + Tailwind)
npm run update-content
```
This script:
- Downloads official Svelte LLM-optimized docs (svelte.dev/llms-full.txt)
- Extracts complete Tailwind docs from GitHub via Repomix
- Updates component snippet timestamps
- Generates content summary
**Sources:**
- Svelte/SvelteKit: Official LLM-optimized text file (100% coverage)
- Tailwind CSS: GitHub repository via Repomix extraction (249 MDX files)
- Snippets: Local curated component examples (43 files)
## 🛡️ Security Features
### Input Validation
- **Pattern Matching**: Only alphanumeric, hyphens, underscores, and dots allowed
- **Length Limits**: Configurable maximum input lengths
- **Path Sanitization**: Removes directory traversal attempts
- **Bounds Checking**: Ensures file access stays within allowed directories
### Error Handling
- **Safe Error Messages**: No sensitive information exposed to clients
- **Structured Logging**: JSON-formatted audit logs for security monitoring
- **Error Classification**: Different handling for different error types
- **Graceful Degradation**: Fallback responses for non-critical failures
### File System Security
- **Path Validation**: Verifies resolved paths are within base directories
- **File Size Limits**: Prevents resource exhaustion attacks
- **Read-Only Operations**: No write operations exposed to clients
- **Cache Isolation**: Content caching doesn't expose file system structure
## 📊 Performance Features
### Caching System
```typescript
// Automatic content caching with configurable timeout
const fileService = new SecureFileService(
1024 * 1024, // Max file size
5 * 60 * 1000 // Cache timeout (5 minutes)
);
```
### Resource Management
- **Memory Limits**: File size restrictions prevent memory exhaustion
- **Cache Cleanup**: Automatic removal of expired cache entries
- **Async I/O**: Non-blocking file operations
- **Error Recovery**: Graceful handling of resource limitations
