How to Query Live Google Cloud Storage Data in Claude Desktop
Model Context Protocol (MCP) is an emerging, open-source standard for connecting LLMs with external services and data sources. Through MCP Servers, AI clients can perform actions like opening Jira tickets, posting Slack messages, committing GitHub branches and more. With CData MCP Servers, these capabilities expand exponentially.
In this article, we guide the reader through installing the CData MCP Server for Google Cloud Storage, configuring the connection to Google Cloud Storage, and asking questions of the data in Claude Desktop.
Prerequisites
You need to download Claude Desktop (download) and create an account before continuing.
Overview
Here's a quick overview of the steps:
- Download and install the CData MCP Server for Google Cloud Storage
- Configure the connection to Google Cloud Storage
- Ask questions about the data in Claude Desktop
Step 1: Download and install the CData MCP Server
- To begin, navigate to https://www.cdata.com/solutions/mcp/connectors and download the CData MCP Server for Google Cloud Storage.
- Find and double-click the installer to begin the installation.
- Follow the prompts to complete the installation.
When the installation is complete, you are ready to configure your MCP Server by connecting to Google Cloud Storage.
Step 2: Configure the connection to Google Cloud Storage
- After installation, the CData MCP Server configuration wizard should open automatically.
NOTE: If the wizard does not open automatically, search for "CData MCP Server" in the Windows search bar and double-click the application.

- Click the dropdown menu in MCP Configuration > Configuration Name and select "
"
- Name the configuration (e.g. "cdatagooglecloudstorage") and click "OK."
NOTE: This name is used as the name for the MCP server and as the prefix for all of the MCP Server's tools.
Connecting to Google Cloud Storage
Authenticate with a User Account
You can connect without setting any connection properties for your user credentials. After setting InitiateOAuth to GETANDREFRESH, you are ready to connect.
When you connect, the Google Cloud Storage OAuth endpoint opens in your default browser. Log in and grant permissions, then the OAuth process completes
Authenticate with a Service Account
Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes.
You need to create an OAuth application in this flow. See the Help documentation for more information. After setting the following connection properties, you are ready to connect:
- InitiateOAuth: Set this to GETANDREFRESH.
- OAuthJWTCertType: Set this to "PFXFILE".
- OAuthJWTCert: Set this to the path to the .p12 file you generated.
- OAuthJWTCertPassword: Set this to the password of the .p12 file.
- OAuthJWTCertSubject: Set this to "*" to pick the first certificate in the certificate store.
- OAuthJWTIssuer: In the service accounts section, click Manage Service Accounts and set this field to the email address displayed in the service account Id field.
- OAuthJWTSubject: Set this to your enterprise Id if your subject type is set to "enterprise" or your app user Id if your subject type is set to "user".
- ProjectId: Set this to the Id of the project you want to connect to.
The OAuth flow for a service account then completes.
Enter the appropriate connection properties in the configuration wizard.
- Click "Connect" to authenticate with Google Cloud Storage through OAuth.
NOTE: The configuration wizard should open your browser and ask you to sign into Google Cloud Storage. If your browser does not open, close the configuration wizard and re-open the application using "Run as Administrator" (see below).
- Finally, click "Save Configuration" to save the MCP server.
NOTE: This saves the configuration details to a separate file and updates the Claude Desktop configuration file (claude_desktop_config.json) to start the CData MCP Server when the Claude Desktop client starts.
With the CData MCP Server configured, you are ready to start asking questions of your live data from Claude.
Step 3: Ask AI for answers from live Google Cloud Storage data
Now that we have installed the CData MCP Server and configured a connection, we are ready to start with Google Cloud Storage data in Claude Desktop.
- Open Claude Desktop. It may take a moment for the MCP Servers to start, but you will see the list of servers and tools available in the Claude interface (look for the settings icon below the prompt bar).
You can individually enable and disable specific tools by clicking on the server name.
- Now that you have connected, you can ask Claude questions about the Google Cloud Storage data. For example: "Can you give me a quantitative analysis about my closed-won opportunities by industry?"
NOTE: Claude may need to explore the Google Cloud Storage data to make sense of it before it can begin answering questions of the data. The tabular model presented by CData alongside the database tools available simplify the data exploration and analysis for an LLM.
