Google Cloud Storage MCP server

Connect Google Cloud Storage to Claude, ChatGPT, Cursor, Claude Code, Codex, Gemini, GitHub Copilot and any other MCP client, for your whole team. Metorial adds security, governance, and tracing, and gives everyone one Magic MCP URL to connect.

What you can do with the Google Cloud Storage MCP server

Ask your agent in plain language. Each of these maps to a real tool on the server.

  • Use the manage lifecycle rules tool in Google Cloud Storage
  • Use the get bucket tool in Google Cloud Storage
  • Use the manage bucket tool in Google Cloud Storage
  • Use the upload object tool in Google Cloud Storage
  • Use the manage bucket iam tool in Google Cloud Storage
  • Use the manage pub/sub notifications tool in Google Cloud Storage

How teams use Google Cloud Storage with agents

Cloud Storage holds the files behind your systems: exports, backups, media and datasets. An agent can list and read objects, upload results, and manage bucket lifecycle rules and access.

Read exports

Find the latest export in a bucket and read it for analysis.

Store results

Upload generated reports or files with the right metadata.

Lifecycle rules

Add a rule that moves old objects to a cheaper storage class or deletes them.

Bucket access

Review bucket IAM bindings and remove public access that should not be there.

Tools to start with

  • List Objects: Prefix and delimiter listing.
  • Manage Lifecycle Rules: Automatic class changes and deletion.
  • Manage Bucket IAM: Who can access a bucket.

Sign-in and permissions

Cloud Storage accepts OAuth or a service account. With a service account, the IAM roles on each bucket decide what the agent can read or write, so grant Storage Object Viewer where it only needs to read.

Sign-in options on Metorial: OAuth, Service Account.

Supported Tools

manage_lifecycle

Manage Lifecycle Rules

Get or set lifecycle management rules on a Cloud Storage bucket. Lifecycle rules automate storage class transitions, object deletion, and cleanup of incomplete uploads based on configurable conditions.

get_bucket

Get Bucket

Get detailed information about a Cloud Storage bucket including its location, storage class, versioning status, lifecycle rules, website configuration, labels, and encryption settings.

manage_bucket

Manage Bucket

Create, update, or delete a Cloud Storage bucket. When creating, specify a name and optionally a location, storage class, and versioning. When updating, provide any fields to modify. When deleting, the bucket must be empty.

upload_object

Upload Object

Upload a new object to a Cloud Storage bucket or overwrite an existing one. Provide the object name (path) and its text content. Optionally attach custom metadata key-value pairs.

manage_bucket_iam

Manage Bucket IAM

Get or set IAM policies on a Cloud Storage bucket. Use **action: "get"** to retrieve the current policy, or **action: "set"** to replace the entire policy with the provided bindings. Use **action: "add_binding"** or **action: "remove_binding"** to modify individual bindings without replacing the full policy.

manage_notifications

Manage Pub/Sub Notifications

List, create, or delete Pub/Sub notification configurations on a Cloud Storage bucket. Notifications deliver event messages to a Pub/Sub topic when objects are created, updated, deleted, or archived.

list_buckets

List Buckets

List Cloud Storage buckets in the configured project. Supports filtering by name prefix and pagination for large result sets.

delete_object

Delete Object

Permanently delete an object from a Cloud Storage bucket. Optionally specify a generation number to delete a specific version of a versioned object.

update_object_metadata

Update Object Metadata

Update metadata on an existing object in a Cloud Storage bucket. Supports changing content type, content disposition, cache control, custom metadata, and object holds.

list_objects

List Objects

List objects in a Cloud Storage bucket. Supports filtering by name prefix, delimiter-based folder simulation, and listing all object versions.

copy_object

Copy Object

Copy an object within or between Cloud Storage buckets. The source object remains unchanged. Can also be used to rename or move an object by setting **deleteSource** to true.

get_object

Get Object

Get an object's metadata and optionally download its content from a Cloud Storage bucket. By default only returns metadata; set **includeContent** to true to return a binary-safe downloadable file.

Connect Google Cloud Storage to your AI client

Every client uses the same Magic MCP URL, and so does any other MCP client. Add it once and sign in with SSO.

  1. Enable Google Cloud Storage in Metorial. In your Metorial portal, enable the Google Cloud Storage MCP server and sign in with the account that owns the data. Access stays governed by your team policies.
  2. Add a custom connector. Open Customize, then Connectors. Select Add, then Custom, then Web.
  3. Paste your Metorial MCP URL. Name it Metorial, paste your Magic MCP URL (<your-magic-mcp-url>) and continue.
  4. Sign in. Select Add and sign in to load Google Cloud Storage tools.

Run Google Cloud Storage through the Metorial gateway

One governed layer for every app your agents reach, not a separate connector per tool.

  • Give Google Cloud Storage and every other app to your whole team through one MCP gateway, behind your SSO.
  • Scope which teams and agents can use Google Cloud Storage tools with role-based access control, and trace every call.
  • Prefer to run it yourself? Metorial is open source and self-hostable.
