Your agent never holds the credential. 100,000 calls a month free." canonical: https://actionlake.com/connectors/google-cloud-storage updated: 2026-10-22 --- Connectors · Files & documents # Google Cloud Storage MCP server for AI agents. actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Google Cloud Storage and the rest of your systems. It gives your agent 87 Google Cloud Storage actions (33 reads, 41 writes and 13 that wait for a confirmation) and holds the Google Cloud Storage credential itself, so the agent never does. It paces Google Cloud Storage's limits and records every call. Connecting Google Cloud Storage needs your own Google Cloud Storage OAuth app and one admin sign-in. [Connect Google Cloud Storage free](https://actionlake.com/console?start=sandbox) [See pricing](https://actionlake.com/pricing) 100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you. `claude mcp add --transport http actionlake https://connect.actionlake.com/mcp` the first call ``` do { action: "gcp_cloud_storage.anywhere_caches.get", intent: "check which Google Cloud Storage account is connected" } # Anywhere caches: get · read · 1 upstream call ``` - 87 actions in one signed file - 33 read look, never change - 41 write create and update - 13 wait for a yes destructive, confirmed first Set up ## Connect Google Cloud Storage in three steps. 1. 01 ### Add actionlake to Claude. Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us. `https://connect.actionlake.com/mcp` 2. 02 ### Connect Google Cloud Storage. OAuth 2.0, authorization code with PKCE. You register your own OAuth app with Google Cloud Storage, an admin signs in once, and you paste the app's client id and secret and the tokens from that sign-in; actionlake renews the access token from then on. actionlake stores what you paste write-only, sealed under your tenant's key. Before the first sign-in, Google Cloud Storage needs an OAuth app of your own, registered in its developer portal. actionlake has no Google Cloud Storage app to lend you. - `access_token` Access token from one sign-in with your own OAuth app - `refresh_token` Refresh token from the same sign-in; the access token is renewed from it - `client_id` Google OAuth client id (Google Cloud console > APIs & Services > Credentials; enable the Cloud Storage JSON API on… - `client_secret` Google OAuth client secret ``` account { op: "connections.requirements", service: "gcp_cloud_storage" } # free: exactly what to paste, and what is found for you ``` 3. 03 ### Make the first call. Check before a write. Ask in plain words; Claude picks the action. Before anything changes, `check` validates the call and prices it, for free. ``` do { action: "gcp_cloud_storage.anywhere_caches.get" } # anywhere caches: get · read · 1 upstream call check { action: "gcp_cloud_storage.buckets.insert", input: { … } } # free: inputs, permissions, cost and confirmations, nothing sent ``` Google Cloud Storage at a glance **Sign-in** OAuth 2.0, authorization code with PKCE. You register your own OAuth app with Google Cloud Storage, an admin signs in once, and you paste the app's client id and secret and the tokens from that sign-in; actionlake renews the access token from then on. **You provide** `access_token` `refresh_token` `client_id` `client_secret` **Limits we pace to** 600 calls a minute, per connection **API covered** Storage v1 JSON API (Discovery revision 20261013)`storage.googleapis.com` **Built from** Google Cloud Storage's documentation, read 22 October 2026[storage.googleapis.com](https://storage.googleapis.com/$discovery/rest?version=v1) [cloud.google.com](https://cloud.google.com/storage/docs/json_api/v1) **Service file** Version 1.0.0, signed (Ed25519) **Cached reads** 29 of 33 reads, for up to 5 minutes; a write clears what it affects **Shared entities** 2, so ask can line Google Cloud Storage up with your other systems **Data** Processed and stored in Sydney, Australia.

These are all of them: - Buckets: delete `gcp_cloud_storage.buckets.delete` - Objects: delete `gcp_cloud_storage.objects.delete` - Folders: delete `gcp_cloud_storage.folders.delete` - Notifications: delete `gcp_cloud_storage.notifications.delete` - Managed folders: delete `gcp_cloud_storage.managed_folders.delete` - Folders: delete recursive `gcp_cloud_storage.folders.delete_recursive` - Projects hmac keys: delete `gcp_cloud_storage.projects_hmac_keys.delete` - Rapid caches: disable `gcp_cloud_storage.rapid_caches.disable` - Anywhere caches: disable `gcp_cloud_storage.anywhere_caches.disable` - Bucket access controls: delete `gcp_cloud_storage.bucket_access_controls.delete` - Object access controls: delete `gcp_cloud_storage.object_access_controls.delete` - Default object access controls: delete `gcp_cloud_storage.default_object_access_controls.delete` - Operations: cancel `gcp_cloud_storage.operations.cancel` A destructive action runs only with `confirm: true`. Under the `human` policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after. do gcp_cloud_storage.buckets.delete confirm_policy: **human** Buckets: delete? **intent:** the user asked me to buckets: delete run suspended · waiting for a named person · key _gcp-cloud-storage-agent_ cannot confirm itself In the console, or from an emailed signed link. a key for this connector ``` account { op: "keys.create", name: "gcp-cloud-storage-agent", allowed_actions: ["gcp_cloud_storage.*"], cap_calls: 2000, confirm_policy: "human_for_writes", approval_rules: [ { match: "gcp_cloud_storage.buckets.delete", approver: "lead@example.com" }, { match: "gcp_cloud_storage.objects.delete", approver: "lead@example.com" }, { match: "gcp_cloud_storage.folders.delete", approver: "lead@example.com" } ] } ``` Illustrative. Scoped to Google Cloud Storage only, capped at 2,000 upstream calls, every write confirmed, and the destructive ones approved by a named person. Cost ## What Google Cloud Storage costs on actionlake. Every Google Cloud Storage action is one upstream call, the only thing actionlake bills. Searching, `check`, `cost`, `account` and any call Google Cloud Storage refused with 401, 403, 429 or a 5xx are free. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000. - 1 upstream call per action all 87 Google Cloud Storage actions - 8 actions page each page of a long list is one call -

The free call account { op: "connections.requirements", service: "gcp_cloud_storage" } lists exactly what to paste. **Can an AI agent delete or change things in Google Cloud Storage?** Only if its key allows it, and only with an explicit confirmation. 13 Google Cloud Storage actions are destructive, including buckets: delete, objects: delete and folders: delete. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it. **Will an AI agent use up my Google Cloud Storage API limit?** actionlake paces every call to the limits in the Google Cloud Storage service file: 600 calls a minute per connection. Repeated reads are answered from cache (29 Google Cloud Storage actions can be), which never reaches Google Cloud Storage. **What does a Google Cloud Storage action cost?** One upstream call, the only unit actionlake bills. A list that pages bills one call per page (8 Google Cloud Storage actions page). Cache hits, searches, dry runs and calls Google Cloud Storage refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000. **Which Google Cloud Storage API does it cover?** The storage v1 JSON API (Discovery revision 20261013) at storage.googleapis.com. It is built from Google Cloud Storage's documentation as read on 22 October 2026. 87 actions in 13 areas, each one in the signed service file (version 1.0.0). **Does actionlake keep my Google Cloud Storage data, and where?** actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Google Cloud Storage credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models. **Which AI clients can use it?** Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names. ## More connectors like Google Cloud Storage Joins with, on shared entities - [Canvas LMS 2](https://actionlake.com/connectors/canvas-lms) - [Mailchimp 2](https://actionlake.com/connectors/mailchimp) - [Salesforce Marketing Cloud Engagement 2](https://actionlake.com/connectors/salesforce-marketing-cloud-engagement) - [Bynder 2](https://actionlake.com/connectors/bynder) - [LlamaCloud 2](https://actionlake.com/connectors/llamacloud) - [Wistia 2](https://actionlake.com/connectors/wistia) Browse - [All Files & documents connectors](https://actionlake.com/connectors/category/files-and-documents) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
