[Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) 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][toolbox] to
expose your developer assistant tools to a MySQL instance:
* [Cursor][cursor]
* [Windsurf][windsurf] (Codium)
* [Visual Studio Code][vscode] (Copilot)
* [Cline][cline] (VS Code extension)
* [Claude desktop][claudedesktop]
* [Claude code][claudecode]
* [Gemini CLI][geminicli]
* [Gemini Code Assist][geminicodeassist]
[toolbox]: https://github.com/googleapis/genai-toolbox
[cursor]: #configure-your-mcp-client
[windsurf]: #configure-your-mcp-client
[vscode]: #configure-your-mcp-client
[cline]: #configure-your-mcp-client

## 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
1. **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.
