neon-postgres

A guide to Neon Serverless Postgres, a hosted PostgreSQL database service that can automatically adjust resources as needed. It covers setup, connections, branching, scaling, authentication, and Neon tools and APIs.

In plain words
What is it for?
Use it when setting up Neon, connecting applications, configuring branches, scaling, read replicas, connection pooling, Neon Auth, or Neon’s CLI, MCP server, REST API, or SDKs.
Why use it?
It helps developers choose and configure Neon correctly instead of piecing together setup and database guidance from separate sources.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
