Setup

Cloud SQL for SQL Server MCP Server (Data Plane: Connecting and Querying)

This section covers connecting to a Cloud SQL for SQL Server instance.

1. Verify Environment Variables: The extension requires the following environment variables to be set before the Gemini CLI is started:

   • CLOUD_SQL_MSSQL_PROJECT: The GCP project ID.
   • CLOUD_SQL_MSSQL_REGION: The region of your Cloud SQL instance.
   • CLOUD_SQL_MSSQL_INSTANCE: The ID of your Cloud SQL instance.
   • CLOUD_SQL_MSSQL_DATABASE: The name of the database to connect to.
   • CLOUD_SQL_MSSQL_IP_ADDRESS: The IP address of the Cloud SQL instance.
   • CLOUD_SQL_MSSQL_USER: The database username.
   • CLOUD_SQL_MSSQL_PASSWORD: The password for the database user.

2. Handle Missing Variables: If a command fails with an error message containing a placeholder like ${CLOUD_SQL_MSSQL_PROJECT}, it signifies a missing environment variable. Inform the user which variable is missing and instruct them to set it.

3. Handle Permission Errors: If you encounter permission errors, ensure the user has the Cloud SQL Client (roles/cloudsql.client) role and the correct database-level permissions. You can provide these links for assistance:

   • Cloud SQL Permissions: https://cloud.google.com/iam/docs/roles-permissions/cloudsql

Cloud SQL Admin MCP Server (Control Plane: Creating and Managing Infrastructure)

This section covers administrative operations like managing clusters, instances, and users.

1. Handle Permission Errors:
   • For operations that create, get, list, delete, or update resources, the user needs the Cloud SQL Admin (roles/cloudsql.admin) role.
   • For read-only operations (get/list), the Cloud SQL Viewer (roles/cloudsql.viewer) role is sufficient.
   • If an operation fails due to permissions, identify the type of operation and recommend the appropriate role. You can provide these links for assistance:

     • Cloud SQL Permissions: https://cloud.google.com/sql/docs/sqlserver/iam-permissions
