The file sharing protocol for agents.

How it works

One link. That's it.

Your agent makes something — a report, an image, a CSV, a PDF. ClawDrop gives it a link. You open the link anywhere: browser, Slack, email, iMessage. It just works.

Built for OpenClaw

Your agent already speaks it.

If you use OpenClaw, your agent already knows how to drop files to ClawDrop. No setup. No config. Ask your agent to make something, and it gives you a link.

Every link works everywhere. Drop it in Slack — it unfurls with a preview. Email it — it shows the file name and size. Post it on Twitter — rich card. The protocol handles everything.

Every surface

The protocol handles everything.

A ClawDrop link isn't just a download. It knows where it's being opened and adapts.

The vision

One protocol. Every agent. Every surface.

CFTP (Claw File Transfer Protocol) is the open standard for how AI agents share files. Any agent can speak it. Any surface can display it. The protocol is free and open — you can even self-host it.

ClawDrop is the canonical registry: the place where links live, previews render, and files get delivered. We built a pipe, not a platform.

POST / → clawdrop.io/xK7m2pQ

GET /xK7m2pQ → file or preview

GET /xK7m2pQ?m → { name, size, type }

DELETE /xK7m2pQ → 204 gone

Pricing

Free. No catch.

Upload files, get links. Free tier is generous. If you need more, it's usage-based — you pay for what you use. No tiers. No seats. No sales calls.

Usage-based

Links cost money to keep alive. That's also how we make money. No minimums, no contracts.

For developers

Build on the protocol.

ClawDrop is just HTTP. No SDK required. If your language can make an HTTP request, it speaks CFTP.

$ curl -F "[email protected]" https://clawdrop.io

Python

import requests

def drop(filepath, api_key=None):
    headers = {"Accept": "application/json"}
    if api_key:
        headers["X-API-Key"] = api_key
    with open(filepath, "rb") as f:
        r = requests.post(
            "https://clawdrop.io",
            files={"file": f},
            headers=headers
        )
    return r.json()

# url = drop("report.pdf")[" url"]

JavaScript

async function drop(filepath, apiKey) {
  const form = new FormData();
  form.append("file", await fs.openAsBlob(filepath));
  const headers = { Accept: "application/json" };
  if (apiKey) headers["X-API-Key"] = apiKey;
  const res = await fetch("https://clawdrop.io", {
    method: "POST", body: form, headers,
  });
  return res.json();
}

The protocol is open. The spec is public. Fork it if we disappear.
