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. Works out of the box with Claude, Cursor, and any MCP host. -MCP-native: drop-in server for any MCP host -JSON output for agent pipelines -Guest mode: upload without an account -Idempotent uploads: same file = same URL -Password-gated & one-time links -Free tier forever

Hey PH 👋 I built transfa because every time I needed an AI agent to hand a file to a human, I hit the same wall - Dropbox requires login, WeTransfer has a 2 GB cap and a slow UX, S3 presigned URLs are too raw to manage at scale. The 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. tf upload anything is three keystrokes. The link lands on your clipboard. No account needed for the first few uploads. Free tier includes a dashboard, audit log, and MCP integration. Would love to hear how you use it - especially if file handoff is the ugly last step in your agent pipeline.
