A Postgres-Backed MCP Server in ~20 Lines

Short summary

A concise tutorial showing how to build a Postgres-backed MCP (Model Context Protocol) server in about 20 lines of code, deployed as a Neon Function co-located with the database to eliminate cross-region network hops. The server uses Drizzle ORM, Hono, and the MCP SDK's streamable HTTP transport, exposing database tools that any MCP client like Claude or Cursor can call. Each database branch gets its own isolated MCP endpoint.
