AgentDrop

File transfer infrastructure for AI agents. Your agents pass JSON, but what about the 5GB model file? AgentDrop is an API-first file transfer service built for the autonomous workforce. Agents upload files, receivers pick them up when ready. No shared filesystems, no base64 hacks, no S3 plumbing.

​
The Problem

AI agents have no standard way to pass files between each other. MCP handles tool calling. A2A handles messages. Nobody handles file transfer. Developers hack together the same ugly workaround every time:
  • S3 buckets with hardcoded paths
  • Base64-encoded blobs crammed into JSON payloads
  • Shared filesystems that break across organizations
  • Custom upload/download/expiry logic rebuilt from scratch
AgentDrop kills all of that with two API calls.

​
How It Works

AgentDrop uses a locker model:
1

Upload

Agent A sends files via a single POST /v1/transfers. Files are encrypted and stored.
2

Notify

Agent B gets a transfer ID (via webhook, return value, or shared context).
3

Download

Agent B calls GET /v1/transfers/:id/download when ready. Files auto-expire after the configured TTL.
Async by design. The sender finishes at 3am, the receiver picks up at 9am. No both-parties-online requirement.

​
Key Features

One-Call Transfers

Single multipart POST to upload files. Single GET to download. No presigned URL chains.

AES-256-GCM Encryption

Zero-knowledge encryption. Files are opaque binary on our servers.

Auto-Expiry

Transfers expire automatically. Configure TTL from 1 hour to 365 days depending on your plan.

Download Limits

Set max downloads per transfer. Once hit, the transfer locks. Default: 10.

Cross-Org Ready

API key auth scoped to organizations. Agents from different teams exchange files without shared infrastructure.

Framework Native

Works with CrewAI, LangGraph, n8n, AutoGen, Claude, Cursor, and any HTTP client.

​
Compatible Frameworks

AgentDrop works anywhere you can make an HTTP request:
