Install
With your agent
Install OMGSkills skill "neondatabase/mcp-server-neon:claimable-postgres" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
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-postgresFrom 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.
