What is MCP Server for MySQL?

This is a Model Context Protocol server based on NodeJS that provides read-only access to MySQL databases for large language models (LLMs). It allows AI assistants to securely inspect the database structure and execute queries without modifying the data.

How to use MCP Server for MySQL?

You can install it with one click using the Smithery tool or manually install it using npm/pnpm. After installation, configure the MySQL connection information, and then the AI assistant can query your database through natural language.

Applicable scenarios

Suitable for scenarios where AI needs to analyze database content but is not allowed to modify it, such as data analysis assistants, report generation, and database structure queries.

Main Features

Secure Query ExecutionExecute read-only SQL queries through the mysql_query tool. All queries run in read-only transactions to prevent data modification.
Database Structure InspectionAutomatically discover and provide complete table structure information, including column names, data types, indexes, and relationships.
Multiple Security ProtectionsIncludes security features such as SQL injection protection, query whitelisting, rate limiting, and read-only transaction enforcement.
Performance OptimizationOptimizations such as connection pooling, query caching, and streaming of large result sets ensure efficient queries.
