List Connections: List the storage connections (S3, R2, Spaces, B2, ...) this access grant can see.

List Buckets: List the buckets of one storage connection that this access grant can see.

List Objects: List objects and folders in a bucket, filtered to prefixes this access grant may read. Folders end with "/" and appear as kind "prefix".

Give your AI agent access to S3-compatible storage without handing it your access keys. quickS3 is a hosted MCP server: the agent signs in through your browser, borrows only the roles you pick, and moves files through short-lived links.

🔐 Why use it

No keys on the machine. OAuth sign-in in your browser. Your storage credentials stay encrypted in quickS3.
Scoped by roles. Delegate read-only access to one folder, or write access to one bucket. Deny rules always win.
Files never pass through the chat. Downloads and uploads use short-lived signed links, and bytes go straight to your provider.
No delete, no silent overwrite. There is no delete, copy, move, or rename tool.
Audited and revocable. Every agent action is logged. Revoke a grant in one click, and grants expire after 30, 60, or 90 days.

AWS S3, Cloudflare R2, Backblaze B2, DigitalOcean Spaces, Wasabi, MinIO, Azure Blob Storage, and other S3-compatible services.

🚀 Get started

Create a quickS3 organization at quicks3.com and add a storage connection.
Add https://quicks3.com/mcp as a remote MCP server in Claude, ChatGPT, Codex, or any client that supports Streamable HTTP with OAuth.
Approve the agent and pick its roles.

For Claude Code and Codex, the open source quickS3 plugin installs the server and the quicks3-operator skill.

🔐 Why use it

🧰 Tools

☁️ Providers

🚀 Get started

list_connections	List the storage connections (S3, R2, Spaces, B2, ...) this access grant can see.
list_buckets	List the buckets of one storage connection that this access grant can see.
list_objects	List objects and folders in a bucket, filtered to prefixes this access grant may read. Folders end with "/" and appear as kind "prefix".
create_download_link	Create a short-lived download link (valid 5 minutes, single use) for one object. Download the file by following the link, e.g. with `curl -L -o output.bin "<uri>"`. quickS3 never sees or stores the file contents; the link redirects directly to your storage provider.
create_share_link	Create a public share link for one object. Anyone who has the link can download the file without a quickS3 account, until it expires. Use this only when the user asks to share a file with someone; to download a file yourself, use create_download_link. The link never outlives this access grant: revoking the grant, or losing read access to the file, disables it.
create_upload_url	Create a short-lived presigned upload URL (valid 15 minutes) for one object. Upload the file directly to your storage provider with an HTTP PUT to the returned `url`, sending every header in the returned `headers` (e.g. `curl -H "x-ms-blob-type: BlockBlob" -T localfile "<url>"` for Azure). Uploads fail without those headers. quickS3 never sees or stores the file contents.
