Google Cloud Storage is a scalable object storage service. The Google Cloud Storage MCP server lets you manage buckets, upload and download files, and organize your storage using natural language.

​
What Can It Do?

  • Upload and download files to and from GCS buckets
  • Create and manage buckets with custom configurations
  • Search and browse files with filtering and pagination
  • Copy and move files within or across buckets

​
Where to Use It

Add Google Cloud Storage as a tool to any agent. The agent can then interact with Google Cloud Storage conversationally, choosing the right actions based on context. To add an MCP tool to your agent:
  1. Open your agent’s configuration
  2. Click Add tools → Connect an app with MCP
  3. Search for the integration and select it
  4. Authenticate with your Google account
You can control which tools your agent has access to. After adding an integration, click on it to enable or disable specific tools based on what your agent needs.

​
In Workflows (Via Agent Node)

For automated pipelines, use an Agent Node with Google Cloud Storage tools. This gives you the flexibility of an agent within a deterministic workflow.

​
As a Custom MCP Node

You can also create a standalone MCP node for a specific action. This generates a reusable node that performs one task, useful when you need the same operation repeatedly in workflows.
To create a custom MCP node:
  1. Go to your node library and search for the integration
  2. Click Create a node with AI
  3. Describe the specific action you want (e.g., “List all files in my data bucket”)
  4. Test the node and save it for reuse
Custom MCP nodes are single-purpose by design. For tasks that require multiple steps or dynamic decision-making, use an agent instead.

Troubleshooting

Agents are smart enough to chain multiple API calls together. If results seem off, check the agent’s step-by-step reasoning.
