Simple MySQL MCP Server

Simple MySQL MCP Server is an MCP server that connects AI assistants to relational MySQL databases using the Model Context Protocol. Built with TypeScript and structured around clean architecture principles, the server enables developers, data analysts, and engineers to interact with their database instances directly through conversational interfaces. It integrates with MySQL servers configured via environment variables, giving language models structured access to database tools, resources, and analysis prompts. The server implements tools to execute validated SQL queries and describe table structures, while actively guarding against dangerous commands such as unconstrained deletions and database drops. In addition to executing queries, it exposes standardized MCP resources for reading database lists, inspecting active tables, and fetching schemas. Preconfigured prompt templates further assist users in generating detailed table analyses, discovering large tables by row count, and retrieving overall database summaries. By managing database connection reuse and structured error handling, Simple MySQL MCP Server provides a dependable bridge for inspecting data models and running administrative database queries securely.

How to install and configure Simple MySQL MCP Server

1. Clone the project repository and install required packages by running npm install. 2. Configure your database connection by creating a .env file containing MYSQL_HOST, MYSQL_PORT, MYSQL_USER, MYSQL_PASSWORD, and MYSQL_DATABASE. 3. Build the server binary with npm run build. You can verify your setup using npm run test:connection. 4. Add the server to your claude_desktop_config.json file under mcpServers. Specify node as the command, pass the full path to dist/index.js in args, and include your MySQL environment variables under env.

What you can do with Simple MySQL MCP Server

• Inspecting relational schemas by querying available tables and column definitions across connected MySQL database instances. - Executing filtered SELECT queries to extract operational records without leaving your AI chat client interface. - Analyzing table structures and column types using the built-in describe_table tool to debug schema issues. - Identifying large database tables and storage bottlenecks using predefined prompt templates like find_large_tables for capacity planning. - Generating database overview summaries and tracking table metadata directly through standardized MCP resource URIs.
