neon-postgres

Guidance for using Neon Serverless Postgres, a hosted version of the PostgreSQL database that can adjust computing resources separately from stored data. It covers setup, connections, authentication, APIs, command-line tools, and platform APIs.

In plain words
What is it for?
Use it when building or debugging an application that stores data in Neon, including local development, authentication, data APIs, CLI tasks, or automation through Neon’s APIs.
Why use it?
It helps you find the right Neon setup and connection approach without piecing together changing documentation yourself.

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-postgres 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 yesterday.

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

Neon is a serverless Postgres platform that separates compute and storage to offer autoscaling, branching, instant restore, and scale-to-zero. It's fully compatible with Postgres and works with any language, framework, or ORM that supports Postgres.

Neon Documentation

The Neon documentation is the source of truth for all Neon-related information. Always verify claims against the official docs before responding. Neon features and APIs evolve, so prefer fetching current docs over relying on training data.

Fetching Docs as Markdown

Any Neon doc page can be fetched as markdown in two ways:

  1. Append .md to the URL (simplest): https://neon.com/docs/introduction/branching.md
  2. Request text/markdown on the standard URL: curl -H "Accept: text/markdown" https://neon.com/docs/introduction/branching

Both return the same markdown content. Use whichever method your tools support.

Finding the Right Page

The docs index lists every available page with its URL and a short description:

https://neon.com/docs/llms.txt

Common doc URLs are organized in the topic links below. If you need a page not listed here, search the docs index — don't guess URLs.

What Is Neon

Use this for architecture explanations and terminology (organizations, projects, branches, endpoints) before giving implementation advice.

Link: references/what-is-neon.md

Getting Started

Use this for first-time setup: org/project selection, connection strings, driver installation, optional auth, and initial schema setup.

Link: references/getting-started.md

Connection Methods & Drivers

Use this when you need to pick the correct transport and driver based on runtime constraints (TCP, HTTP, WebSocket, edge, serverless, long-running).

Link: references/connection-methods.md

Serverless Driver

Use this for @neondatabase/serverless patterns, including HTTP queries, WebSocket transactions, and runtime-specific optimizations.

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.
