What is the Model Context Protocol (MCP)?
MCP is a standardized protocol designed to manage context between large language models (LLMs) and external systems. Neon MCP Server implements this protocol to bridge natural language and the Neon API.

Overview
What is Neon MCP Server?
Neon MCP Server is an open-source tool that lets you interact with your Neon Postgres databases in natural language. It acts as a bridge between natural language requests and the Neon API, enabling you to manage tasks such as creating projects and branches, running queries, and performing database migrations seamlessly.
How to use Neon MCP Server?
Set up by running npx neonctl@latest init for quick OAuth-based configuration in Cursor, VS Code, and Claude Code, or connect to the remote managed server via OAuth or an API key. You need an MCP client, a Neon account, Node.js >= 18, and if IP Allow is enabled, add the listed static IPs to your allowlist. Configure your client with the URL https://mcp.neon.tech/mcp and optionally add headers, query params, or use the deprecated SSE endpoint https://mcp.neon.tech/sse.
Key features of Neon MCP Server
- Natural language interaction with Neon databases
- Simplified database management without writing SQL
- Accessibility for non-developers to manage databases
- Database migration support using Neon's branching
- Run queries, describe schemas, and view performance metrics
- Read-only mode and tool category filtering for access control
Use cases of Neon MCP Server
- Create a new Postgres database and a table with specified columns
- Run a migration to alter an existing table
- Get a summary of all Neon projects and their data
- Provision Neon Auth or Data API through natural language
- Reset a branch from its parent or compare database schemas
Frequently asked questions
What are the prerequisites for using Neon MCP Server?
You need an MCP client application, a Neon account, and Node.js version 18 or higher. If IP Allow is enabled on your account, you must add `34.192.103.46` and `23.22.233.166` to your allowlist.
Can I restrict the Neon MCP Server to read-only operations?
Yes. Read-only mode restricts tools to read-only actions (e.g., listing projects, querying data) and is enabled either by selecting read-only in the OAuth UI or by adding `?readonly=true` to the server URL. The `run_sql` tool remains available only for read-only queries.
Is the Neon MCP Server recommended for production use?
No. The README warns that it is intended for local development and IDE integrations only and should not be used in production environments, as it can execute powerful operations that may lead to accidental or unauthorized changes.
How does authentication work?
Two methods: OAuth-based (recommended, no API key needed) or API key–based (set `Authorization: Bearer <key>` header). OAuth scopes (`read`, `write`, `*`) control permissions, and you can also use the `org_id` or `project_id` in prompts to scope operations to specific organizations or projects.
