Transfa.sh: Headless file-sharing tool built for AI agents and automated workflows
By

Best dunked in coffee. Better still, swap for a fresh one.
Summary
Transfa.sh is a file-sharing tool designed specifically for AI agents and automated workflows, not human users. It allows AI agents (like Claude, Cursor) to upload files and return parseable signed URLs without requiring a browser, login, or account setup. Key features include MCP-native integration, JSON output for agent pipelines, guest mode, idempotent uploads, password-gated links, and a free tier. The tool solves the problem of AI agents silently failing when trying to share outputs with humans due to the lack of headless, API-friendly file sharing solutions.
Key quotes
· 3 pulledThe real moment was watching a Claude agent silently fail at the 'share this output with the user' step. Not because the code was wrong - because no tool existed that worked headlessly, returned a parseable URL, and required zero setup for a first run.
Most file sharing tools assume a human with a browser. Transfa assumes a process with an API budget and a deadline.
tf upload model.pt returns a signed URL in seconds. No browser, no account required.
