Stream Vessel

StreamVessel connects Claude to the cloud storage you already own. Add your S3-compatible accounts to StreamVessel once (AWS S3, Cloudflare R2, Backblaze B2, Wasabi, DigitalOcean Spaces, MinIO, IDrive e2 and others), then ask Claude to work with your files in plain language. What Claude can do:

• Find files by name or pattern at any depth, browse folders and list buckets
• Read text files, or check a file's size and type without opening it
• Write small text files, and create short-lived download and upload links for anything larger
• Copy, move and delete single files or whole folders, and total up a folder before changing it
• Handle very large uploads in parts, and find and clear abandoned uploads that keep costing money
• Count a bucket's objects and size, and check whether a bucket is readable by anyone on the internet

You stay in control:

• Choose the access level when you connect: Read, Write or Full (only Full can delete or move)
• Limit the connection to particular storage accounts, buckets or folders; everything else stays invisible to Claude
• Connections shared with you by teammates keep the permissions they were shared with
• Every connection expires (90 days by default, a year at most), and you can revoke it at any time from the MCP page in StreamVessel
• Claude asks before running any tool that changes or deletes data

Your files stay in your storage. StreamVessel signs requests with your own credentials, which are stored encrypted, and file contents pass through only when you ask Claude to read or write them. Tool-call logging is off unless you turn it on. Requires a StreamVessel account (sign in with Google, GitHub or email) and at least one S3-compatible storage connection.
