MySQL using MCP	docs	2	Connect your IDE to MySQL using Toolbox.

Model Context Protocol (MCP) is an open protocol for connecting Large Language Models (LLMs) to data sources like MySQL. This guide covers how to use MCP Toolbox for Databases to expose your developer assistant tools to a MySQL instance:

• Cursor
• Windsurf (Codium)
• Visual Studio Code (Copilot)
• Cline (VS Code extension)
• Claude desktop
• Claude code
• Gemini CLI
• Gemini Code Assist

Set up the database

1. Create or select a MySQL instance.

Use Tools

Your AI tool is now connected to MySQL using MCP. Try asking your AI assistant to list tables, create a table, or define and execute other SQL statements.

The following tools are available to the LLM:

1. list_tables: lists tables and descriptions
2. execute_sql: execute any SQL statement

{{< notice note >}} Prebuilt tools are pre-1.0, so expect some tool changes between versions. LLMs will adapt to the tools available, so this shouldn't affect most users. {{< /notice >}}
