mcp-postgres-server vs hayba

mcp-postgres-server: This project is an MCP server designed to provide secure and structured access to PostgreSQL databases for models. It supports various PostgreSQL environments, including local, Docker, and cloud-based instances, with robust security features like read-only enforcement and SSH tunneling.; hayba: Hayba is an agentic engine that enables AI agents like Claude or GPT to directly author Unreal Engine 5 scenes by spawning actors, building PCG graphs, and validating physics. It provides a spatial-first approach with a PCG SQLite registry, a cognitive map, and a visual grounding sidecar, extending AI capabilities for complex 3D world creation.
