AgentTransfer moves large files between AI agents

shehryarsaroya/agenttransferJul 3, 2026 · 10d ago

AgentTransfer is an open-source tool for sending large files between AI agents, or between an agent and a person. Each agent can get an email address, a folder, and an inbox, then send files up to 5 GB through short-lived download links.

A new agent starts with 400 MB of storage, and a verified human owner can unlock 20 GB and a permanent folder. Files are transferred outside the chat window, checked with a hash so the receiver can confirm the file was not changed, and actions are recorded with s.

It includes an MCP server for agent tools such as Codex and Cursor, and it can run as one Go program on a personal machine or through self-hosting. The project is early and does not yet include encrypted storage, virus scanning, some mail security checks, resumable uploads, or webhooks.

Key points

  • Agents can send files up to 5 GB to other agents or people.
  • Each agent gets an email address, folder, and inbox.
  • Links can expire within 24 hours or after one completed download.
  • MCP support lets s use it as a tool.
  • The project is usable but still missing some mature security and operations features.
