MCP Server MySQL

MCP Server MySQL is an open-source Model Context Protocol server with 2,100+ stars on GitHub that gives large language models safe, read-only access to MySQL databases, so an AI assistant can inspect your schema and answer questions about your data without ever being able to modify it.

Overview

The server plugs into any MCP-compatible client — tools such as Claude Desktop, Cursor and other agent hosts — and exposes a MySQL database through the protocol’s standard tool interface. Once connected, the model can list tables, read column definitions and relationships, and run read-only SELECT queries whose results come back as structured data it can reason over. Because every operation is read-only by design, the server is a practical way to let an LLM explore a production-like schema, draft queries, explain what a table holds or check values while answering a question, all without the risk of an accidental UPDATE or DELETE. It is written for the common case of teams who keep business data in MySQL and want their AI tooling to understand that data in context rather than guessing from names alone. The project is MIT licensed and remains actively maintained, with its most recent updates in 2026.

Key Features

• Read-only by design – the server only executes read operations, so models can query freely without write risk.
• Schema inspection – LLMs can enumerate tables and columns to understand a database before querying it.
• Natural-language data questions – ask an agent about your data and let it compose and run the SQL itself.
• Standard MCP protocol – works with any client that supports the Model Context Protocol.
• Self-hosted – runs next to your own database under your own credentials and network rules.
• MIT licensed – free to use, adapt and embed in internal tooling.

💳 Pricing

MCP Server MySQL is free and open source under the MIT license. You run it yourself alongside your own MySQL instance; there is no hosted tier, account or subscription involved.

Who Is It For

Developers and data teams who use MCP-compatible AI assistants and want those assistants to explore MySQL schemas and answer data questions safely, without handing a model write access to a real database.
