Use when you have picked Neon (serverless Postgres) and need to connect correctly from a serverless or edge runtime, wire database branching into dev, preview and CI, or stop being burned by scale-to-zero cold starts and pooler limits — including choosing HTTP versus WebSocket connections and pooled versus direct endpoints for migrations. NOT generic Postgres schema, index, EXPLAIN, RLS or migration-engine work (that is `postgresdb`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Neon — serverless Postgres as a platform Neon is Postgres with three platform features the engine doesn't have: a **serverless driver** that talks over HTTP/WebSocket (so you can query from edge runtimes), **built-in connection pooling**, and **copy-on-write branching** that makes a fork of production data appear instantly. This skill owns that platform layer. The Postgres *engine* underneath — schema, indexes, EXPLAIN, RLS, zero-downtime DDL — is identical to any Postgres 16 and belongs to `../postgresdb/SKILL.md`. Don't re-derive engine craft here; connect correctly and branch correctly. ## When to use / When NOT to use **When to use:** - Code imports `@neondatabase/serverless`, or `DATABASE_URL` points at `*.neon.tech` / `*.aws.neon.tech`. - Connecting from Vercel (Edge/Node), Cloudflare Workers, AWS Lambda, or any serverless/edge function — choosing HTTP `neon()` vs WebSocket `Pool`. - Setting up branching: dev branch off production, a branch per PR in CI, `neonctl` usage, the Neon + Vercel preview integration. …

How to install
mdr add ericrisco/rsc-harness/neon@sha256:1e9f63b2d6490654The line at the top of this page pins the label git:20260729.111532c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
