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".

## Install

```sh
git clone https://github.com/neondatabase/mcp-server-neon /tmp/mcp-server-neon && ln -s /tmp/mcp-server-neon/.agents/skills/claimable-postgres ~/.claude/skills/claimable-postgres
```

## From README

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. Parse connectionstring and claimurl from the JSON response. Write connectionstring to the project's .env as DATABASEURL. 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 .env in one command. Convenient when Node.js is available and the user wants a simple . SDK (neon-new/sdk): Scripts or programmatic provisioning in Node.js. Vite plugin (vite-plugin-neon-new): Auto-provisions on vite dev if DATABASEURL is missing. Use when the user has a Vite project. Browser: User cannot run CLI or API. Direct to https://neon.new.
