FAQ from MySQL MCP Server
What protocol does MySQL MCP Server use?
It implements the Model Context Protocol (MCP) for read‑only database interaction.
How is authentication handled?
Authentication uses a database URL in the format mysql://username:password@host:port/database. Credentials can be passed via environment variables for security.
What runtime dependencies are required?
Node.js and npm are required. The server is installed from a Git repository using npm install and npm link.
Where does the data live?

What are the security recommendations?
Use a MySQL user with minimal read‑only permissions, store credentials in environment variables, and never commit configuration files with passwords to version control.
