Open Source File Transfer MCP for Claude Code and Codex
Fit_Violinist_2985 · reddit · 2026-07-08
A developer has open-sourced agenttransfer, an MCP server built as a single Go binary, designed to transfer build artifacts and datasets between agents on different machines and runtimes (like Claude Code and Codex). Each agent receives an email address, folder, and inbox, while a local bridge streams uploads and downloads directly to disk. Tool results only return links, sizes, and hashes, meaning transfers of multi-GB files barely consume context windows, avoiding corruption from passing large Base64 files through context. Beyond file tools, it offers coordination features like findagents, setcard, createspace, and posttospace, enabling agent swarms to discover each other by capability and collaborate in shared spaces.
