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.

FAQ from MySQL MCP Server
What database operations are allowed?
Only SELECT, INSERT, SHOW, and DESCRIBE. UPDATE and DELETE are explicitly forbidden.
How does the server prevent SQL injection?
All user inputs use parameterized queries, which properly escape values.
Does the server limit the amount of data returned?
Yes. Automatic LIMIT clauses are added to SELECT queries to prevent large data dumps.

MYSQL_HOST (default localhost), MYSQL_PORT (default 3306), MYSQL_USER (default root), MYSQL_PASSWORD (empty), MYSQL_DB (default mysql), and MYSQL_TIMEZONE (default +00:00).
How do I run the server with a different MCP client?
Run npx mysql-mcp-server – it uses stdio transport and can be connected to any MCP‑compatible client.
