What is the Neon MCP Server?

The Neon MCP Server is a server implementation based on the Model Context Protocol (MCP) standard. It serves as a bridge connecting AI assistants (such as Claude) with Neon database services. Through natural language instructions, you can easily manage PostgreSQL databases without writing complex SQL commands.

How to use the Neon MCP Server?

Simply install an MCP client (such as Claude Desktop), configure your Neon API key, and you can start managing databases using natural language. The system supports operations such as creating projects, managing branches, executing SQL queries, and performing migrations.

Use cases

Suitable for developers, data analysts, and team managers to quickly operate databases, especially for users who are not familiar with SQL or in scenarios that require frequent database changes.

Main features

Project managementList, create, describe, and delete Neon projects.

Branch managementCreate, delete, and describe database branches.

SQL operationsExecute SQL queries and transactions, and obtain connection strings.

Schema managementGet database table information and describe table structures.

Safe migrationsTest database changes through temporary branches before committing them.

Advantages and limitations

Advantages

Manage databases without SQL knowledge.

Complete complex database operations through natural language.

The migration process is safe and reliable, with testing before submission.

Supports multiple MCP clients (Claude, Cursor, etc.).

Limitations

Requires Node.js environment support.

Depends on the Neon API key for access.

Complex queries may require multiple interactions for clarification.

How to use

Installation preparation

Ensure that Node.js (v18+) and Claude Desktop are installed.

Get the API key

Get the API key from the Neon console.

Initialize the server

Run the initialization command to configure the API key.

Restart the client

Restart Claude Desktop for the configuration to take effect.

Usage examples

Create a database and tablesCreate a complete database structure through natural language instructions.

Safe migrationsAdd a new column without affecting existing data.

Data queryGet a summary of database content.

🚀 Neon MCP Server

The Neon MCP Server enables interaction with Neon via natural - language commands using Claude Desktop or any MCP client.

The Model Context Protocol (MCP) is a newly 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 allows 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 in it, with the following fields: id, name, email, and password.
I want to run migrations on my project "my-project" to change the users table and add a new column "created_at".
Can you give me a summary of all my Neon projects and the data in each project?

🚀 Quick Start

📦 Installation

Automatic Installation via Smithery:

To automatically install the Neon MCP server via Smithery:

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

Requirements

Node.js >= v18.0.0
Claude Desktop
Neon API Key - You can generate it in the Neon console. Learn more or Quick access

Local Usage

Run npx @neondatabase/mcp-server-neon setup to initialize the configuration.
After configuration, run npx @neondatabase/mcp-server-neon start to start the server.

💻 Usage Examples

Basic Usage

Here are some example commands to interact with the Neon MCP Server:

# Create a new database
mcp create database mydb

# Drop an existing table
mcp drop table users

# Execute an SQL query
mcp query "SELECT * FROM users LIMIT 10"
