neon

neon is a skill for Claude Code from bobmatnyc/claude-mpm-skills. It costs 49 tokens per session (5,065 once invoked), scanned A, original, MIT.

A guide to Neon, a serverless PostgreSQL database service that can scale its computing resources and create separate database branches. Database branches are disposable copies useful for development and testing.

In plain words
What is it for?
Use it for serverless applications, database copies for feature work, and deployments with platforms such as Vercel or Netlify.
Why use it?
It helps teams give development and staging work isolated databases and deploy PostgreSQL applications without manually managing database servers.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

neon scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Neon Serverless Postgres Skill


progressive_disclosure: entry_point: summary: "Serverless Postgres with autoscaling, branching, and instant database provisioning" when_to_use: - "When needing serverless Postgres" - "When building edge and serverless apps" - "When implementing database branching for dev/staging" - "When using Drizzle, Prisma, or raw SQL" quick_start: - "Create project on Neon console" - "Get connection string" - "Connect with Drizzle/Prisma/pg" - "Deploy with Vercel/Netlify" token_estimate: entry: 75-90 full: 3800-4800

Core Concepts

Neon Architecture

  • Projects: Top-level container for databases and branches
  • Databases: Postgres databases within a project
  • Branches: Git-like database copies for development
  • Compute: Autoscaling Postgres instances
  • Storage: Separated from compute for instant branching

Key Features

  • Serverless: Pay-per-use, scales to zero
  • Branching: Instant database copies from any point in time
  • Autoscaling: Compute scales based on load
  • Instant Provisioning: Databases ready in seconds
  • Connection Pooling: Built-in PgBouncer support

Connection Strings

Standard Connection

# Direct connection (for migrations, admin tasks)
DATABASE_URL="postgresql://user:[email protected]/dbname"

# Pooled connection (for application queries)
DATABASE_URL="postgresql://user:[email protected]/dbname?sslmode=require"

Connection Pooling

# PgBouncer pooled connection (recommended for serverless)
DATABASE_URL="postgresql://user:[email protected]/dbname?sslmode=require"

# Direct connection for migrations
DIRECT_URL="postgresql://user:[email protected]/dbname"

Drizzle ORM Integration

Setup

// drizzle.config.ts
import type { Config } from "drizzle-kit";

export default {
  schema: "./src/db/schema.ts",
  out: "./drizzle",
  driver: "pg",
  dbCredentials: {
    connectionString: process.env.DATABASE_URL!,
  },
} satisfies Config;

// src/db/index.ts
import { drizzle } from "drizzle-orm/neon-http";
import { neon } from "@neondatabase/serverless";

const sql = neon(process.env.DATABASE_URL!);
export const db = drizzle(sql);

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

neon is a skill published in the GitHub repository bobmatnyc/claude-mpm-skills (75 stars, last pushed 1mo ago), licensed MIT. It adds 49 tokens to every session and 5,065 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
