What it does
Provision instant temporary Postgres databases via Claimable Postgres by Neon (neon.new) with no login, signup, or credit card. Supports REST API, CLI, and SDK. Use when users ask for a quick Postgres environment, a throwaway DATABASE_URL for prototyping/tests, or "just give me a DB now". Triggers include: "quick postgres", "temporary postgres", "no signup database", "no credit card database", "instant DATABASE_URL", "npx neon-new", "neon.new", "neon.new API", "claimable postgres API".
FIRST: Use the parent neon skill for a Neon overview, getting started with Neon, Neon development best practices, and more.
If the neon skill is not installed, fetch it from https://neon.com/docs/ai/skills/neon/SKILL.md or install it with:
npx skills add neondatabase/agent-skills --skill neon
Claimable Postgres
Instant Postgres databases for local development, demos, prototyping, and test environments. No account required. Databases expire after 72 hours unless claimed to a Neon account.
Quick Start
curl -s -X POST "https://neon.new/api/v1/database" \
-H "Content-Type: application/json" \
-d '{"ref": "agent-skills"}'
Parse connection_string and claim_url from the JSON response. Write connection_string to the project's .env as DATABASE_URL.
For other methods (CLI, SDK, Vite plugin), see Which Method? below.
Which Method?
- REST API: Returns structured JSON. No runtime dependency beyond
curl. Preferred when the agent needs predictable output and error handling. - CLI (
npx neon-new@latest --yes): Provisions and writes.envin one command. Convenient when Node.js is available and the user wants a simple setup. - SDK (
neon-new/sdk): Scripts or programmatic provisioning in Node.js. - Vite plugin (
vite-plugin-neon-new): Auto-provisions onvite devifDATABASE_URLis missing. Use when the user has a Vite project. - Browser: User cannot run CLI or API. Direct to https://neon.new.
Auto-provisioning
If the agent needs a database to fulfill a task (e.g. "build me a todo app with a real database") and the user has not provided a connection string, provision one via the API and inform the user. Include the claim URL so they can keep it.
