S3 Browser & Cloud Storage AI Manager — Stream Vessel

Manage S3-compatible storage across providers, search, edit and transfer files, and let AI agents work with your storage via MCP.

WORK ACROSS S3. LET AI WORK WITH IT TOO. We built Stream Vessel as a desktop-style workspace for Amazon S3 and S3-compatible storage, for developers, SREs, DevOps teams and data engineers. Instead of switching between provider consoles, local editors and transfer tools, you can browse, search, edit and move objects from one Chrome extension. KEY BENEFITS • Work across storage: open multiple panes side by side and drag files or folders between buckets, accounts and S3-compatible providers. Background transfers show progress and let you retry failed items. • Find and fix files faster: search the current folder or an entire bucket by filename or full path, with wildcard support. Open code, configs and text in Monaco—the editor engine behind VS Code—and save changes directly back to storage. • Move data where it needs to go: upload and stream large downloads, preview files, create and organize folders, generate expiring presigned links, and transfer files directly between Google Drive and S3-compatible storage. • Keep access scoped: connections can be limited to a specific bucket or prefix, so Stream Vessel works naturally with least-privilege credentials. AI THAT WORKS ON YOUR STORAGE Connect any AI agent and any MCP-compatible clients and let them work with the storage itself. Ask it to find outdated configuration values, inspect logs, identify what is consuming space, reorganize a folder, upload new files or clean up stale objects. The agent receives controlled MCP access—not your S3 access keys—and permissions can be limited and revoked. DIRECT BY DESIGN Your file transfers go directly between your browser and your storage provider rather than through a Stream Vessel file-transfer server. Stream Vessel requests host access only for the storage endpoints you use. For everyday work, that means fewer context switches: inspect a bucket, fix a config, move data between providers or hand a bounded task to an AI agent without assembling a separate toolchain. One workspace for files, providers and AI agents. YOUR PERMISSIONS, MINIMIZED Stream Vessel asks for the least access it needs - and nothing more: Access to your S3 endpoints, on demand only: Stream Vessel does NOT request standing access to your browsing or to "all your websites." When you open a connection, it asks - through Chrome's own permission prompt - for access to just that connection's host (for example, amazonaws.com for AWS, or the endpoint you entered for other providers). You approve access per connection, and you can revoke it anytime from Chrome's extension settings. Storage: Saves your connections and preferences locally on your device. Credentials for a connection saved on this device never leave your browser. Alarms: Schedules periodic checks for extension updates so you stay on the latest version. Identity: Used when you sign in - to Stream Vessel with Google or GitHub, or to Google when you choose to import from or send to Google Drive. It lets Stream Vessel ask the provider for a sign-in token. The sign-in page is the provider's own, and Stream Vessel never sees your password. Nothing is requested until you click one of those actions, and for Drive, Stream Vessel receives access only to the items you pick - never to your Drive as a whole. Analytics: Anonymous usage analytics (page views, feature usage) are sent to Google Analytics to help improve the extension. No personal data, file contents, object names, or credentials are collected or shared. CONTACT US Please send your questions, error reports, and feature requests to support@streamvessel.com
