mcp-postgres-server vs agent-harness-generator

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.; agent-harness-generator: MetaHarness is a unique tool that acts as a factory for AI agent frameworks, generating custom, repo-aware agent harnesses from any GitHub repository or a blank slate. It provides a branded, npm-publishable package with a CLI, scoped memory, governance policy, and integration with various agent hosts like Claude Code and OpenAI Codex, all designed to run locally without external servers.
