```

## Import Type Examples

### Import Provider

```
ccswitch://v1/import?resource=provider&app=claude&name=My%20Provider&endpoint=https%3A%2F%2Fapi.example.com&apiKey=sk-xxx
```

### Import MCP Server

```
ccswitch://v1/import?resource=mcp&apps=claude,codex&config=%7B%22command%22%3A%22uvx%22%2C%22args%22%3A%5B%22mcp-server-fetch%22%5D%7D&name=mcp-fetch
```

### Import Prompt Preset

```
ccswitch://v1/import?resource=prompt&app=claude&name=%E4%BB%A3%E7%A0%81%E5%AE%A1%E6%9F%A5&content=%23%20%E8%A7%92%E8%89%B2%0A%E4%BD%A0%E6%98%AF%E4%B8%80%E4%B8%AA%E4%B8%93%E4%B8%9A%E7%9A%84%E4%BB%A3%E7%A0%81%E5%AE%A1%E6%9F%A5%E4%B8%93%E5%AE%B6
```

### Import Skill

```
ccswitch://v1/import?resource=skill&name=my-skill&repo=owner/repo&directory=skills/my-skill&branch=main
```

## Generate Deep Links

### Manual Generation

1. Prepare parameters
2. Assemble the URL following V1 protocol format
3. URL-encode special characters

**Example**:

```javascript
const params = new URLSearchParams({
  resource: 'provider',
  app: 'claude',
  name: 'My Provider',
  endpoint: 'https://api.example.com',
  apiKey: 'sk-xxx'
});

const url = `ccswitch://v1/import?${params.toString()}`;
```

### Online Tool

Using CC Switch's official online deep link generator tool is more convenient.

## Using Deep Links

### Click the Link

Click a deep link in a browser or other application:

1. The system asks whether to open CC Switch
2. After confirming, CC Switch opens
3. An import confirmation dialog is displayed
4. Confirm the import

### Import Confirmation

A confirmation dialog is shown before import, containing:

- Import type
- Configuration preview
- Confirm/Cancel buttons

**Security tip**: Only import configurations from trusted sources.

## Protocol Registration

### Automatic Registration

CC Switch automatically registers the `ccswitch://` protocol during installation.

### Manual Registration

If the protocol is not registered correctly:

**macOS**:
Reinstall the app, or run:
```bash
/usr/bin/open -a "CC Switch" --args --register-protocol
```

**Windows**:
Reinstall the app, or check the registry:
```
HKEY_CLASSES_ROOT\ccswitch
```

**Linux**:
Check the `MimeType` configuration in the `.desktop` file.

## Security Considerations

### Sensitive Information

Deep links may contain sensitive information (e.g., API Keys):

- Do not share links containing API Keys in public
- Remove or replace sensitive information before sharing
- Use secure channels to transmit links

### Source Verification

Before import, CC Switch will:

1. Validate the data format
2. Display a configuration preview
3. Require user confirmation

### Malicious Link Protection

CC Switch checks:

- Whether the data format is valid
- Whether required fields are complete
- Whether configuration values are within reasonable ranges

## Example Links

### Example: Import Claude Provider

```
ccswitch://v1/import?resource=provider&app=claude&name=Test%20Provider&apiKey=sk-xxx&endpoint=https%3A%2F%2Fapi.example.com
```

### Example: Import MCP Server

```
ccswitch://v1/import?resource=mcp&name=mcp-fetch&apps=claude,codex,gemini&config=%7B%22command%22%3A%22uvx%22%2C%22args%22%3A%5B%22mcp-server-fetch%22%5D%7D
```

## Troubleshooting

### Link Won't Open

**Check**:
1. Is CC Switch installed
2. Is the protocol registered correctly
3. Is the link format correct

### Import Failed

**Possible causes**:
- Base64 encoding error
- JSON format error
- Missing required fields

**Solutions**:
1. Check the original JSON format
2. Re-encode in Base64
3. Ensure all required fields are present
