What is the MySQL MCP server?

Connect MySQL to Claude, Cursor or any other MCP client and it stops being a tab you switch to. # MySQL MCP Server Spring Boot server implementing Model Context Protocol (MCP) for MySQL database operations. ## Features - Execute SELECT queries - List all tables in database - Get table schema information ## API ### Tools - query -. The mysql mcp server is what makes that connection.

What the server does

  • Execute SELECT queries
  • List all tables in database
  • Get table schema information

Installation

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • query — Execute a SELECT SQL query and return results
  • Input — sql (string)
  • Returns — List of query results (truncated after 4000 characters)
  • Note — Only SELECT queries are allowed
  • listAllTablesName — List all table names in the database
  • getTableSchema — Get schema information for a specific table
  • Tools — The Tools tool exposed by this server

Credentials and setup notes

Configuration is passed through the environment: SPRING_DATASOURCE_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Worth knowing first

  • 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.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

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. MySQL's toolset — query, Input, Returns and 4 more — is a fair guide to whether it matches your workflow. It is maintained by kioyong; worth a glance at recent repository activity before you build anything load-bearing on it.
