MCP Integration Test with Full Authentication

This test demonstrates how to use the MCP integration with proper authentication.

Prerequisites:
1. AIM backend server running (http://localhost:8080)
2. User account created (via OAuth or local registration)
3. JWT token obtained from login

Note: This is an integration test that requires a running backend server
and valid user credentials.
