mcp-server-demo

The `database.py` file hardcodes MySQL root user credentials ('root', '123456') for a local database connection. This is a critical security vulnerability for anything beyond an isolated, ephemeral demo. The `subprocess.Popen` calls in `src/a2a/manager.py` are used for internal agent orchestration with fixed module names, posing a low risk of arbitrary command execution. Inter-service communication relies on fixed `localhost` ports without explicit authentication, which could be a risk if `localhost` network access is compromised. The `src/compliance_warning/service.py` attempts to 'auto-fix' LLM-generated JSON by replacing escaped quotes, which could lead to unexpected parsing or resource exhaustion if presented with a maliciously crafted payload.
