Show HN: Facebook marketplace arbitrage tool

Hi HN! I am a 19 year old dev from Australia. Over here, lots of people leave their unwanted items on the sidewalk, but there’s usually nothing wrong with them.

While saving up to travel, I built an app that made it really easy to list them (and stuff I had lying around my house) online. Using it meant I didn’t need a second job which was nice.

A dev recently reached out to me asking if I could turn the valuation feature into an mcp so I decided to spin it off into its own product.

A cool use case we’re playing around with is connecting it to open claw and arbitraging facebook marketplace, I plan on making it even easier to spin up in the coming days :)

Check out the demo and let me know your thoughts/feedback!
