We built file sharing that actually works for AI agents - here's why

Hey PH community 👋

We just launched transfa.sh - file sharing built for AI agents and developers.

The problem we kept running into: every time an agent needed to hand a file to a human

(or another agent), the options were terrible. Dropbox requires login. WeTransfer assumes a browser. S3 presigned URLs work but you end up building a whole wrapper around them.

So we built the missing primitive.

tf upload model.pt

That's it. You get a signed share link back in under 2 seconds. No account needed for the first few uploads - guest mode works out of the box.

What makes it different for agentic use cases:

- MCP-native server for Claude, Cursor, and any MCP host

- JSON output mode so agents can parse URLs, hashes, and expiry times

- Idempotent uploads - same file hash returns the same URL, safe to retry in loops

- Password-gated and one-time links

- Free tier forever

We're a small team and launching today. Would genuinely love feedback - especially from

Anyone building agentic pipelines where file handoff is currently the awkward last step.

Happy to answer any questions about how it works under the hood.
