A hybrid approach is recommended: use codegen as a starting point, aggressively prune generated tools, rewrite descriptions to explain when and why to use each tool, and build higher-level tools that encapsulate multi-step workflows. Neon's own MCP server follows this philosophy, using their TypeScript SDK selectively and adding workflow-level abstractions on top. ## Full article daily.dev links to this article rather than hosting it.
