Neondatabase MCP Server Neon

The Neon MCP Server is a server based on the Model Context Protocol (MCP) standard, used to manage the context interaction between large - language models (LLMs) and the Neon database. It supports performing database operations through natural language instructions, such as creating projects, managing branches, running SQL queries, and migrations.

What is the Neon MCP Server?

The Neon MCP Server is a service based on the Model Context Protocol (MCP) standard. It allows you to interact with the Neon database through natural language (e.g., English). You can directly tell the AI assistant your requirements, and it will automatically perform the corresponding database operations.

How to use the Neon MCP Server?

Simply install the service and connect to an MCP - supported client such as Claude Desktop, then describe your database requirements as if you were having a conversation with a person.

Use cases

Suitable for developers and teams who need to operate databases quickly, especially when you don't want to memorize complex SQL commands or switch tools frequently.

Main features

Project managementCreate, view, and delete Neon projects

Branch managementCreate and delete database branches

SQL operationsExecute SQL queries and transactions

Schema managementView table structures and get database table information

Safe migrationTest database changes through a temporary branch before applying them

Advantages and limitations

Advantages

No need to memorize complex commands. You can operate the database using natural language.

The migration function ensures the safety and reliability of database changes.

Seamless integration with AI assistants such as Claude.

Limitations

Requires Node.js environment support.

Currently only supports the Neon database.

Complex queries may require multiple interactions for confirmation.

How to use

Installation preparation

Ensure that Node.js (version 18.0.0 or higher) and Claude Desktop are installed.

Get the API key

Get your API key from the Neon console.

Initialize the service

Run the initialization command to set up the MCP server.

Restart the client

Restart Claude Desktop to load new features.

Usage examples

Create a new databaseCreate a complete database structure through natural language instructions.

Safe migrationTest database changes without affecting the production environment.

🚀 Neon MCP Server

The Model Context Protocol (MCP) is a new, standardized protocol for managing context between large language models (LLMs) and external systems. In this repository, we provide an installer and an MCP server for Neon.

This enables you to use Claude Desktop or any MCP client to interact with Neon via natural language commands, such as:

Let's create a new Postgres database named "my-database". Then create a table named users with the following columns: id, name, email, and password.
I want to run migrations on my project "my-project" to add a new column "created_at" to the users table.
Can you give me a summary of all my Neon projects and the data in each project?

🚀 Quick Start

Installation via Smithery

To automatically install the Neon MCP server for Claude Desktop via Smithery:

npx -y @smithery/cli install neon --client claude

Prerequisites

Node.js >= v18.0.0
Claude Desktop
Neon API Key - You can generate it through the Neon console. Learn more or click here for quick access.

Local Usage

Run npx @neondatabase/mcp-server-neon init $NEON_API_KEY
Restart Claude Desktop
You should now be able to try a simple command, such as List all my Neon projects

Migrations

Migrations are a way to manage changes to the database schema over time. With the Neon MCP server, LLMs can safely perform migrations via separate "start" and "commit" commands.

The "start" command accepts a migration and runs it on a new temporary branch. Upon return, this command prompts the LLM to test the migration on that branch. Then, the LLM can use the "commit" command to apply the migration to the original branch.
