I have been into working with AI agents and LLMs for a while. I hit up Craigslist at least once a day browsing the free items. I may post once a month for something I'm trying to get rid of.

I usually fail to list stuff on Craigslist because I don't like to take the time to go through merchandising my item. As MCP has been gaining popularity, it dawned on me to build an agentic version of Craigslist. LLMs are great at making up descriptions. I just want to snap a picture of something and have it merchandised and posted for me.

This is how fastlist.org was born. Connect your favorite LLM up to FastList and see how fast you can post an item.

One of the coolest things was trying to figure out an agentic first signup/login flow. As I've played with it, having an AI check for an item every morning has become trivial.
