What is the MySQL MCP server?
MySQL MCP server exists for a simple reason — assistants are far more useful when they can act on MySQL directly instead of describing what you should do.

What you get
This project was created as a learning exercise to explore MCP (Model Context Protocol) concepts.
- List available MySQL tables as resources
- Read table contents
- Execute SQL queries with proper error handling
- Secure database access through environment variables
- Comprehensive logging
Setting it up
The server ships on PyPI as mysql-mcp-server, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Configuration and credentials
You will need 5 environment variables: MYSQL_HOST, MYSQL_PORT, MYSQL_USER, MYSQL_PASSWORD, MYSQL_DATABASE. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Before you rely on it
- It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
- MCP clients confirm each tool call by default. Leave that on until you have watched what the mysql mcp server does with a few real requests.
Choosing this one
This sits in the database access group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. It is maintained by youngsu5582; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against MySQL's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
