What is the Google Cloud Storage MCP server?

It is a hosted Model Context Protocol server that lets AI agents work with your Google Cloud Storage buckets and objects. Agents can list and inspect buckets, search and read object metadata, upload files, copy, move, and delete objects, create buckets, and generate signed download links.

Is the Google Cloud Storage MCP server free?

You can start for free. Gumloop’s free tier lets you connect the Google Cloud Storage MCP server and begin using it at no cost, and paid plans start at $37/month as your usage grows. The storage itself is billed by Google Cloud on your own account.

Do I need credentials to connect Google Cloud Storage?

Yes. This server uses a Google Cloud service account key, not a Google account login. You create a service account with Storage permissions, download its JSON key, and paste it into Gumloop once. Gumloop stores it securely, and the service account’s short-lived tokens refresh on their own.

Which AI clients can I use with the Google Cloud Storage MCP server?

Any MCP-compatible client. That includes Gumloop, Claude, Cursor, and frameworks like LangChain. The same hosted server URL works across all of them.

Can I combine Google Cloud Storage with other integrations?

Yes. An agent can chain Cloud Storage with 100+ other integrations, so it can generate a file, upload it to a bucket, and post the signed link to Slack in the same run.

The server works within the permissions of the service account key you provide, so an agent can only reach the buckets and objects that key allows. Uploads send a file from Gumloop into your bucket, and downloads return a signed or public URL rather than routing the file’s contents back through Gumloop. See trust.gumloop.com for more on Gumloop’s security practices.

Can the Google Cloud Storage MCP server change my storage, or only read it?

Both. It reads buckets and object metadata and generates download links, and it can write: uploading files, copying and moving objects, deleting objects, and creating buckets. Moving and deleting are destructive, so scope those automations carefully. It cannot delete buckets, and it does not manage IAM permissions, lifecycle rules, versioning, or retention policies.

Does download return the file’s contents?

No. The download tool generates a signed URL, which is time-limited, or a public URL for the object. It does not stream the file’s bytes back through the server, so an agent gets a link to share or fetch rather than the raw contents.

What is Google Cloud Storage MCP?

The Google Cloud Storage MCP server gives AI agents access to your GCS buckets and objects. That means agents can list and inspect buckets, search and read object metadata, upload files, copy and move objects between buckets, delete objects, create new buckets, and generate signed download links. It connects to the same object storage your apps and data pipelines use, so an agent can move files around and share them instead of you running gsutil commands or clicking through the console.

Working with cloud storage by hand means a lot of repetitive plumbing: hunting for the right object, generating a temporary share link, copying files between buckets, and cleaning up what is no longer needed. The Google Cloud Storage MCP server hands that work to an AI agent that can find the object, upload the file, and produce a signed URL. Describe what you need moved or shared, and your AI agent will handle the storage step for you.

MCP stands for Model Context Protocol, an open standard that lets AI agents call external tools. Normally, working with the Cloud Storage API means wiring up a service account, installing a client library, and writing code against its endpoints. Gumloop wraps all of that behind a hosted server: add your Google Cloud service account key once. After that, you can list buckets, upload and download files, and move objects just by chatting with your AI agent.

Google Cloud Storage MCP use cases

Archive processed files for data teams

After a pipeline finishes, an agent uploads the outputs to a GCS bucket or moves processed files into an archive bucket, keeping the working bucket clean.

Secure file sharing for ops

An agent generates a signed URL that expires after a set time and sends the link by email or Slack, so a partner can download a file without any standing access.

Asset delivery for content teams

An agent uploads a generated image or document into a bucket and returns a public URL, so the asset is ready to embed or hand off.

Storage cleanup for engineering

An agent searches a bucket by prefix and date range, then deletes or moves the objects that match, so old data does not pile up.

Bucket provisioning for new projects

When a new project spins up, an agent creates a bucket in the right location and storage class so the team has a place to store data from day one.
