This pull request introduces several configuration improvements and minor code changes to enhance local development and deployment reliability. The main updates involve improving environment variable defaults, updating the Docker build process, and providing clearer configuration examples.

Configuration and Environment Improvements:

• Added MCP_PORT and API_BASE_URL variables to .env.example to clarify required environment variables for local development.
• Updated the Dockerfile to copy .env.example into the container, ensuring environment configuration is available in Docker-based deployments.

Codebase Robustness:

• Modified prisma/db.ts to use a default local PostgreSQL connection string if DATABASE_URL is not set, improving developer experience and reducing configuration errors.

Pull request overview

This pull request enhances local development configuration and environment variable management by adding new environment variables to the example file, updating the Docker build process, and providing a default database connection string. However, the changes introduce critical security and deployment concerns that should be addressed.

• Added MCP_PORT and API_BASE_URL to .env.example for clearer configuration documentation
• Introduced default database connection string fallback in prisma/db.ts
• Modified Dockerfile to copy .env.example as .env into the container

Copying .env.example to .env in the Docker container is problematic. The .env.example file is meant to be a template showing which environment variables need to be set, not actual configuration values to be used in production. Docker containers should receive environment variables through proper mechanisms like docker-compose environment variables, Kubernetes secrets, or runtime environment injection. This approach could lead to using example/placeholder values in production deployments.

Suggested change

COPY --from=prerelease /usr/src/app/.env.example ./.env

[Copilot]

Hardcoding database credentials (username: "root", password: "root") as a fallback creates a security risk. If DATABASE_URL is accidentally unset in production, the application would attempt to connect using these insecure default credentials. Instead, consider failing fast with a clear error message when DATABASE_URL is missing, or only use this default in development environments with an explicit check (e.g., checking NODE_ENV).

Suggested change

	const connectionString =
	process.env.DATABASE_URL || "postgresql://root:root@localhost:5432/myhouse";
	let connectionString: string;
	if (process.env.DATABASE_URL) {
	connectionString = process.env.DATABASE_URL;
	} else if (
	process.env.NODE_ENV === "development" ||
	process.env.NODE_ENV === "test"
	) {
	// Development/test fallback connection string
	connectionString = "postgresql://root:root@localhost:5432/myhouse";
	} else {
	throw new Error(
	"DATABASE_URL environment variable is not set. Please configure it before starting the application.",
	);
