# Integrate Claude Agent SDK with You.com MCP

Interactive workflow to set up Claude Agent SDK with You.com's HTTP MCP server.

## Workflow

1. **Ask: Language Choice**
   * Python or TypeScript?

2. **If TypeScript - Ask: SDK Version**
   * v1 (stable, generator-based) or v2 (preview, send/receive pattern)?
   * Note: v2 requires TypeScript 5.2+ for `await using` support

3. **Install Package**
   * Python: `pip install claude-agent-sdk`
   * TypeScript: `npm install @anthropic-ai/claude-agent-sdk`

4. **Ask: Environment Variables**
   * Using standard `YDC_API_KEY` and `ANTHROPIC_API_KEY`?
   * Or custom names?
   * Have they set them?
   * If NO: Guide to get keys:
     - YDC_API_KEY: https://you.com/platform/api-keys
     - ANTHROPIC_API_KEY: https://console.anthropic.com/settings/keys

5. **Ask: File Location**
   * NEW file: Ask where to create and what to name
   * EXISTING file: Ask which file to integrate into (add HTTP MCP config)

6. **Create/Update File**

   **For NEW files:**
   * Use the complete template code from the "Complete Templates" section below
   * User can run immediately with their API keys set

   **For EXISTING files:**
   * Add HTTP MCP server configuration to their existing code
   * Python configuration block:
     ```python
     from claude_agent_sdk import query, ClaudeAgentOptions

     options = ClaudeAgentOptions(
         mcp_servers={
             "ydc": {
                 "type": "http",
                 "url": "https://api.you.com/mcp",
                 "headers": {
                     "Authorization": f"Bearer {os.getenv('YDC_API_KEY')}"
                 }
             }
         },
         allowed_tools=[
             "mcp__ydc__you_search",
             "mcp__ydc__you_express",
             "mcp__ydc__you_contents"
         ]
     )
     ```

   * TypeScript configuration block:
     ```typescript
     const options = {
       mcpServers: {
         ydc: {
           type: 'http' as const,
           url: 'https://api.you.com/mcp',
           headers: {
             Authorization: `Bearer ${process.env.YDC_API_KEY}`
           }
         }
       },
       allowedTools: [
         'mcp__ydc__you_search',
         'mcp__ydc__you_express',
         'mcp__ydc__you_contents'
       ]
     };
     ```

## Complete Templates

Use these complete templates for new files. Each template is ready to run with your API keys set.

## HTTP MCP Server Configuration

All templates use You.com's **HTTP MCP server** for simplicity:

**Python:**
```python
mcp_servers={
    "ydc": {
        "type": "http",
        "url": "https://api.you.com/mcp",
        "headers": {
            "Authorization": f"Bearer {ydc_api_key}"
        }
    }
}
```

**TypeScript:**
```typescript
mcpServers: {
  ydc: {
    type: 'http' as const,
    url: 'https://api.you.com/mcp',
    headers: {
      Authorization: `Bearer ${ydcApiKey}`
    }
  }
}
```

**Benefits of HTTP MCP:**
- ✅ No local installation required
- ✅ Stateless request/response model
- ✅ Always up-to-date with latest version
- ✅ Consistent across all environments
- ✅ Production-ready and scalable
- ✅ Works with existing HTTP infrastructure

## Available You.com Tools

After configuration, Claude can discover and use:
- `mcp__ydc__you_search` - Web and news search
- `mcp__ydc__you_express` - AI-powered answers with web context
- `mcp__ydc__you_contents` - Web page content extraction

## Environment Variables

Both API keys are required:

```bash
# Add to your .env file or shell profile
export YDC_API_KEY="your-you-api-key-here"
export ANTHROPIC_API_KEY="your-anthropic-api-key-here"
```

**Get your API keys:**
- You.com: https://you.com/platform/api-keys
- Anthropic: https://console.anthropic.com/settings/keys

## Validation Checklist

Before completing:

- [ ] Package installed: `claude-agent-sdk` (Python) or `@anthro
