The drive that remembers.

A cloud drive where every change is a version. Go back to any version, compare, restore, and undo it.

Works with AI agents over MCP. By default they propose, you review.

01 · How it works

Four moves. No ceremony.

Nothing to configure. Versioning is on from the first file you drop in, and it covers the whole drive, not just single documents.

  1. 01

    Drop

    Drag in files or whole folders. Only blocks the drive hasn't seen are sent.

  2. 02

    Version

    Every upload, rename, move or delete is one version of the whole drive.

  3. 03

    Travel

    Scrub the timeline and the whole drive shows itself as it was.

  4. 04

    Restore or share

    Bring back a file, a folder or everything. Or share a live or pinned link.

02 · Time travel

See the whole drive as it was.

Not a backup you hope works. The history is the drive: browse it, compare it, bring it back.

Restore

Bring anything back. Then undo that too.

Restore a file, a folder or the whole drive. The restore is a version too, so you can undo it or restore again from the timeline.

Share

Share live, or pin a version.

A live link always shows the latest. A pinned link shows exactly the version you picked.

Duplicate

Fork a drive at any point.

Duplicate a drive as it is now, or as it was on Tuesday. The copy is ready at once.

03 · AI agents over MCP

Agents propose. You decide, file by file.

KDRIVE is an MCP server. Connect an agent with OAuth or an agent token and choose what it may do. Suggestions wait in a review inbox until you accept them.

{
  "mcpServers": {
    "kdrive": {
      "type": "http",
      "url": "https://kdrive.platinum.dev/mcp"
    }
  }
}

Your client opens the browser to sign in, then asks what the agent may do.

  • Read onlydrive:readSee files, folders, versions and history.
  • Suggest changesdrive:proposeRead, and propose changes. Every change waits for your review.
  • Make changesdrive:writeWrite, move and delete, either reviewed first or applied as versions you can undo.

04 · Everything else

The rest of what a drive should do.

One quiet object for everything. What peeks out of the folder tells you what is inside before you open it.

  • Versions

    Every change is a version, marked with who made it: you or an agent.

  • Checkpoints

    Name a moment ("before launch") and come back to it by name.

  • Recently deleted

    Deleted files and folders come back from one list, where they were.

  • Folder upload

    Drop whole folders; they arrive nested exactly as they were on your disk.

  • File history

    Open any file's own history: every kept version, who made it and when.

  • Keyboard-first

    Search with / or ⌘K, jump to the timeline with h, see every shortcut with ?.

05 · Under the hood

History is cheap. Copies are instant.

Every drive is a Platinum volume: durable, versioned storage. Versions live in the volume itself, a duplicate is a fork of it, and an upload sends only what is new.

  • 01

    Durable

    Versions and checkpoints live in the volume itself, not in a copy beside it.

  • 02

    Instant forks

    Duplicating a drive at any point is a fork of the volume, not a copy of every byte.

  • 03

    Content-addressed

    Files are split into 1 MiB blocks. A block the drive already holds is never sent again.

06 · FAQ

Questions, answered plainly.

What counts as a version?

Any change to the drive: an upload, a rename, a move, a delete, a restore. One action is one version of the whole drive, so dropping 200 files at once is one version. Each version records who made it: you, or an agent you connected.

How long is history kept?

Every version from the last 7 days, your newest 50 always, and checkpoints until you remove them.

Can I undo a restore?

Yes. A restore is a version like any other, so you can undo it. If later changes touched the same files, KDRIVE won't overwrite them; restore from the timeline instead.

What happens when I delete something?

It goes to Recently deleted for 7 days, where you can restore it. Its earlier versions stay in the timeline for as long as retention keeps them.

What's the difference between a live and a pinned link?

A live link shows the latest. A pinned link shows one version and never changes. Links can expire after 1 day, 7 days, 30 days or a date you pick, or never.

How do AI agents connect?

KDRIVE is an MCP server. Add its URL to any client that speaks MCP over HTTP and sign in with OAuth, or create an agent token for scripts; a token lasts 30, 90 or 365 days and you can revoke it at any time. You choose read only, suggest changes or make changes, and whether changes wait for your review.

Can an agent mess up my drive?

An agent that suggests changes can't change anything until you accept. An agent that makes changes directly writes versions marked with its name, and you can undo them or restore an earlier version. You can lower its access or disconnect it at any time.

How much space do I get?

10 GB to start, and 100 GB with Plus or 1 TB with Pro (see Pricing). It counts what your drives hold now: past versions and checkpoints don't use it. A duplicate counts as a drive of its own.

What are Platinum volumes?

The durable, versioned storage KDRIVE is built on. Each drive is one volume; versions, checkpoints and duplicates are features of the volume itself.

Change anything. Go back to how it was.

Start with 10 GB. Versioning is on from your first upload.
