Overview

What is MySQL MCP Server?

A Model Context Protocol (MCP) server that provides secure MySQL database operations for AI assistants and other MCP clients. It exposes tools and resources for querying, inserting, and inspecting MySQL databases, with built‑in security restrictions that prevent destructive operations.

How to use MySQL MCP Server?

Install via npm: npm install mysql-mcp-server. Configure using environment variables (MYSQL_HOST, MYSQL_PORT, MYSQL_USER, MYSQL_PASSWORD, MYSQL_DB, MYSQL_TIMEZONE). Integrate with MCP clients such as Claude Desktop by adding the server to the client’s configuration file, or run standalone with npx mysql-mcp-server using stdio transport.

Key features of MySQL MCP Server

Tools: execute_query, get_table_info, insert_data, list_tables
Resources: database metadata and per‑table schema information
Only allows SELECT, INSERT, SHOW, and DESCRIBE operations
SQL injection protection via parameterized queries
Automatic LIMIT clauses on SELECT queries to prevent large data dumps
Connection pooling for efficient resource management

Use cases of MySQL MCP Server

List all tables in a database using the list_tables tool
Examine table structure and schema with get_table_info
