Ms-Sql-Server-MCP-Server

The server exposes `ExecuteQuery` and `ExecuteCommand` methods that accept arbitrary SQL queries/commands directly from the user. Without access to the actual C# implementation details, it's impossible to verify if proper input sanitization, parameterized queries, and robust authentication/authorization are in place. This design pattern presents a critical SQL injection vulnerability if not implemented with extreme care. The mention of 'PII-filtered results' indicates some security awareness, but does not mitigate the fundamental risk of executing user-supplied SQL. Hardcoded connection strings are not present in the provided appsettings.json, but users are required to configure one, which could become a secret management risk if not handled securely.
