What is MySQL MCP Server?

It is a middleware service specifically designed for Cursor IDE, allowing developers to directly interact with MySQL databases without leaving the editor environment. It implements the Model Context Protocol (MCP) standard, encapsulating complex database operations into simple instructions.

How to use MySQL MCP Server?

You can start the service with a simple npm command and then configure the connection parameters in Cursor IDE. After the service is started, you can directly execute SQL queries, browse the database structure and other operations in the editor.

Applicable Scenarios

It is particularly suitable for developers who need to operate databases frequently, such as scenarios like quickly verifying SQL statements, checking table structures, and performing real - time data verification when developing data - driven applications.

Main Features

SQL Query Execution
Supports executing any valid SQL statement and returning structured results
Database Structure Browsing
Visually view the structural information of objects such as tables and views in the database
Database Switching
Quickly switch between multiple databases without reconnecting
Read - only Mode
Enable a secure mode through environment variables to prevent accidental modification of production data
Advantages
Seamlessly integrate into the Cursor IDE workflow, reducing context switching
Lightweight service, starts quickly and has low resource consumption
Supports environment variable configuration for easy deployment in different environments
Open - source project, customizable according to requirements
Limitations
Currently only supports MySQL databases
Requires a Node.js runtime environment
Advanced functions such as transaction management need to be implemented manually

How to Use

Install Dependencies
Ensure that the Node.js environment is installed, and then install project dependencies via npm
Configure Connection
Set environment variables or create an mcp.json file to configure database connection parameters
Start Service
Run the start command, and the service will run in the background waiting for IDE connection
IDE Integration
Add an mcp.json configuration file in Cursor IDE, specifying the service start command and parameters

Usage Examples

Quick Data Query
Need to verify the data structure returned by an API when writing code
Table Structure Check
Need to understand the existing table structure before developing new features
Cross - database Operation
Need to copy data from the development database to the test database
