Cloud SQL for PostgreSQL Admin using MCP	docs	3	Create and manage Cloud SQL for PostgreSQL (Admin) using Toolbox.

This guide covers how to use MCP Toolbox for Databases to expose your developer assistant tools to create and manage Cloud SQL for PostgreSQL instance, database and users:

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

Before you begin

1. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

2. Make sure that billing is enabled for your Google Cloud project.

3. Grant the necessary IAM roles to the user that will be running the MCP server. The tools available will depend on the roles granted:

   • roles/cloudsql.viewer: Provides read-only access to resources.
     • get_instance
     • list_instances
     • list_databases
     • wait_for_operation
   • roles/cloudsql.editor: Provides permissions to manage existing resources.
     • All viewer tools
     • create_database
   • roles/cloudsql.admin: Provides full control over all resources.
     • All editor and viewer tools
     • create_instance
     • create_user
     • clone_instance

Use Tools

Your AI tool is now connected to Cloud SQL for PostgreSQL using MCP.

The cloud-sql-postgres-admin server provides tools for managing your Cloud SQL instances and interacting with your database:

• create_instance: Creates a new Cloud SQL for PostgreSQL instance.
• get_instance: Gets information about a Cloud SQL instance.
• list_instances: Lists Cloud SQL instances in a project.
• create_database: Creates a new database in a Cloud SQL instance.
• list_databases: Lists all databases for a Cloud SQL instance.
• create_user: Creates a new user in a Cloud SQL instance.
• wait_for_operation: Waits for a Cloud SQL operation to complete.
• clone_instance: Creates a clone of an existing Cloud SQL for PostgreSQL instance.

{{< 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 >}}
