cp ~/Library/Application\ Support/Claude/claude_desktop_config.json ~/claude_config_backup.json

Validate JSON Syntax - Use a JSON validator:

python -m json.tool ~/Library/Application\ Support/Claude/claude_desktop_config.json

Restart Claude Desktop - Configuration changes require a restart
Test Connection - Start a new conversation and type:
```
List available Amazon seller tools
```
Verify Tools Load - You should see MCP tools listed with descriptions
Test Basic Operation - Try a simple command:
```
Get my Amazon marketplace information
```

Check Logs - Monitor for any connection issues:

tail -f ~/.amazon-seller-mcp/logs/mcp-server.log

Configuration Troubleshooting

Common configuration issues and solutions:

Issue	Symptoms	Solution
JSON Syntax Error	Claude won't start or shows config error	Validate JSON syntax, check for missing commas/brackets
Command Not Found	MCP server fails to start	Verify `npx` is installed or use full path
Permission Denied	Server startup fails	Check file permissions and user access
Environment Variables	Authentication failures	Verify all required env vars are set correctly
Path Issues	Config file not found	Check file location matches your OS

Configuration Best Practices

✅ Security Best Practices:

Use environment variables for sensitive data
Never commit credentials to version control
Rotate credentials regularly
Use different credentials for different environments
Enable audit logging for production

✅ Performance Best Practices:

Enable caching for frequently accessed data
Set appropriate timeouts for your use case
Use connection pooling for high-volume operations
Monitor memory usage and adjust cache sizes
Implement proper rate limiting

✅ Maintenance Best Practices:

Keep the MCP client updated regularly
Monitor logs for errors and performance issues
Test configuration changes in development first
Document your configuration choices
Set up monitoring and alerting for production

✅ Development Best Practices:

Use separate configurations for dev/staging/prod
Version control your configuration templates
Use descriptive server names for multi-marketplace setups
Enable debug logging during development
Test with sandbox mode before production deployment

❌ Common Mistakes to Avoid:

Don't share configuration files with credentials
Don't use production credentials in development
Don't ignore log files and error messages
Don't skip configuration validation steps
Don't use the same credentials across multiple environments

Configure Permissions - Set required API permissions

Security Best Practices

✅ Use environment variables for credentials
✅ Implement credential rotation
✅ Enable audit logging
✅ Use least-privilege access
❌ Never commit credentials to version control
❌ Don't share credentials across environments

Environment Configuration

# Development
export AMAZON_CLIENT_ID="amzn1.application-oa2-client.dev"
export AMAZON_CLIENT_SECRET="dev_secret"
export AMAZON_REFRESH_TOKEN="dev_refresh_token"

# Production
export AMAZON_CLIENT_ID="amzn1.application-oa2-client.prod"
export AMAZON_CLIENT_SECRET="prod_secret"
export AMAZON_REFRESH_TOKEN="prod_refresh_token"

Extension Points for New Features

1. Adding New API Endpoints

Create new client in src/api/ extending BaseClient
Implement authentication and error handling
Add rate limiting and caching as needed

2. Creating New MCP Tools

Add tool implementation in src/tools/
Register tool in src/server/tools.ts
Follow the tool handler pattern with proper validation

3. Adding New Resources

Create resource provider in src/resources/
Implement resource templates and data fetching
Register in src/server/resources.ts

4. Extending Authentication

Modify src/auth/amazon-auth.ts for new auth flows
Update credential management in credential-manager.ts
Ensure backward compatibility

API Design Guidelines

Tool Implementation Standards:

// Tool handler signature
export async function handleToolName(
  args: ToolArgs,
  context: ToolContext
): Promise<ToolResult> {
  // 1. Validate input arguments
  const validatedArgs = ToolArgsSchema.parse(args);
  
  // 2. Check authentication
  await context.auth.ensureValidToken();
  
  // 3. Execute API operation with error handling
  try {
    const result = await context.apiClient.operation(validatedArgs);
    return { success: true, data: result };
  } catch (error) {
    return { success: false, error: error.message };
  }
}

Resource Provider Standards:

// Resource provider signature
export function registerResourceName(server: McpServer) {
  server.setResourceTemplate(
    'resource://amazon/resource-name/{id}',
    {
      name: 'Resource Name',
      description: 'Resource description',
      mimeType: 'application/json'
    },
    async (uri: string) => {
      // 1. Parse URI parameters
      const { id } = parseResourceUri(uri);
      
      // 2. Fetch data with caching
      const data = await fetchWithCache(`resource-${id}`, () =>
        apiClient.getResource(id)
      );
      
      // 3. Return formatted resource
      return {
        uri,
        mimeType: 'application/json',
        text: JSON.stringify(data, null, 2)
      };
    }
  );
}

Error Handling Patterns:

Use structured error responses with error codes
Implement retry logic with exponential backoff
Log errors with appropriate detail levels
Provide user-friendly error messages

Performance Guidelines:

Implement caching for frequently accessed data
Use connection pooling for HTTP requests
Batch API calls when possible
Monitor and optimize memory usage

Testing Requirements:

Unit tests for all tool handlers
Integration tests for API clients
Mock Amazon SP-API responses for testing
Performance tests for high-load scenarios
