Cloud SQL for MySQL Admin MCP Server

The Cloud SQL for MySQL Model Context Protocol (MCP) Server gives AI-powered development tools the ability to work with your Google Cloud SQL for MySQL databases. It supports connecting to instances, exploring schemas, and running queries.

Features

An editor configured to use the Cloud SQL for MySQL MCP server can use its AI capabilities to help you:

Provision & Manage Infrastructure - Create and manage Cloud SQL instances and users

To connect to the database to explore and query data, search the MCP store for the Cloud SQL for MySQL MCP Server.

Prerequisites

Node.js installed.
A Google Cloud project with the Cloud SQL Admin API enabled.
Ensure Application Default Credentials are available in your environment.
IAM Permissions:
Cloud SQL Viewer (roles/cloudsql.viewer)
Cloud SQL Admin (roles/cloudsql.admin)

Install & Configuration

In the Antigravity MCP Store, click the "Install" button.

[!NOTE] On first use, the installation process automatically downloads and uses MCP Toolbox >=0.26.0. To update MCP Toolbox, use: npm i -g @toolbox-sdk/server@latest To always run the latest version, update the MCP server configuration to use: npx -y @toolbox-sdk/server@latest --prebuilt cloud-sql-mysql-admin.

You'll now be able to see all enabled tools in the "Tools" tab.

[!NOTE] If you encounter issues with Windows Defender blocking the execution, you may need to configure an allowlist. See Configure exclusions for Microsoft Defender Antivirus for more details.

Usage

Once configured, the MCP server will automatically provide Cloud SQL for MySQL capabilities to your AI assistant. You can:

"Create a new Cloud SQL for MySQL instance named 'e-commerce-prod' in the 'my-gcp-project' project."
"Create a new user named 'analyst' with read access to all tables."
