@mastra/gcs

@mastra/gcs

@mastra/gcs mounts a Google Cloud Storage bucket as the filesystem for a Mastra workspace. Use it when agents need durable, shared file access across processes or deployments instead of a local filesystem.

Installation

npm install @mastra/gcs

Usage

import { Agent } from '@mastra/core/agent';
import { Workspace } from '@mastra/core/workspace';
import { GCSFilesystem } from '@mastra/gcs';

const workspace = new Workspace({
  filesystem: new GCSFilesystem({
    bucket: 'my-gcs-bucket',
    // Uses Application Default Credentials by default
    // Or provide a service account key:
    projectId: 'my-project-id',
    credentials: JSON.parse(process.env.GCS_SERVICE_ACCOUNT_KEY),
  }),
});

const agent = new Agent({
  name: 'my-agent',
  model: 'anthropic/claude-opus-4-5',
  workspace,
});
