# Initialize MCP Server Project
Sets up a new MCP server project with the specified configuration level.
## Usage
```
/init [basic|standard|full]
```
## Options
- `basic` - Minimal server with one example tool
- `standard` - Server with tools and resources (default)
- `full` - Complete server with all capabilities
## Implementation
```typescript
async function initializeProject(level: 'basic' | 'standard' | 'full' = 'standard') {
// Create project structure
