quickS3

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. --- ## 🧰 **Tools** | Tool | What it does | Needs | | --- | --- | --- | | `list_connections` | Lists the storage connections the grant can use | Read or write | | `list_buckets` | Lists the buckets on one connection | Read or write | | `list_objects` | Lists one folder level, filtered by your roles | Read | | `create_download_link` | Single-use download link, valid 5 minutes | Read | | `create_share_link` | Public link for someone without an account, 5 minutes to 30 days | Read | | `create_upload_url` | Presigned upload URL, valid 15 minutes, no overwrite by default | Write | --- ## ☁️ **Providers** AWS S3, Cloudflare R2, Backblaze B2, DigitalOcean Spaces, Wasabi, MinIO, Azure Blob Storage, and other S3-compatible services. --- ## 🚀 **Get started** 1. Create a quickS3 organization at [quicks3.com](https://quicks3.com) and add a storage connection. 2. Add `https://quicks3.com/mcp` as a remote MCP server in Claude, ChatGPT, Codex, or any client that supports Streamable HTTP with OAuth. 3. Approve the agent and pick its roles. For Claude Code and Codex, the open source [quickS3 plugin](https://github.com/QuickS3-com/skill) installs the server and the `quicks3-operator` skill. --- quickS3 is a paid service.
