## Development

### Prerequisites

- Node.js 18 or higher
- npm or yarn

### Setup

Install dependencies:
```bash
npm install
```

Build the server:
```bash
npm run build
```

For development with auto-rebuild:
```bash
npm run watch
```

### Testing

```bash
npm test
```

### Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector for development:

```bash
npm run inspector
```



## Running evals

The evals package loads an mcp client that then runs the index.ts file, so there is no need to rebuild between tests. You can load environment variables by prefixing the npx command. Full documentation can be found [here](https://www.mcpevals.io/docs).

```bash
OPENAI_API_KEY=your-key  npx mcp-eval src/evals/evals.ts src/index.ts
```
## Error Handling

The server implements robust error handling for common scenarios:
- Invalid video URLs or IDs
- Unavailable transcripts
- Language availability issues
- Network errors

## Usage Examples

1. Get transcript by video URL:
```typescript
await server.callTool("get_transcript", {
  url: "https://www.youtube.com/watch?v=VIDEO_ID",
  lang: "en"
});
```

2. Get transcript by video ID:
```typescript
await server.callTool("get_transcript", {
