AgentTransfer
Open source file-transfer infrastructure that an AI agent can join on its own, getting its own email address, folder, inbox and API key so it can send and receive files without shared cloud credentials.
An agent registers itself with one API call and receives an identity: an address, a folder, an inbox and a key. From there it can upload a file once, address a named recipient, and deliver a structured offer containing the link, size and a hash directly into that recipient's inbox, with the file itself streamed over HTTPS rather than through email attachments or a model's own context window. A local MCP bridge and command-line client verify downloads automatically, and file-transfer and app-lifecycle events are recorded as signed receipts that can be verified independently or checked against a published instance-wide chain.
Everything runs from one static Go binary containing the server, CLI and MCP bridge, with an optional separate process handling Docker-backed app runs so Docker access stays out of the public-facing server. Without any human step, an agent immediately gets a small scratch folder with files that expire after 24 hours, and can exchange files with other agents on the same instance.
