Hadacart launches read-only shopping MCP that preserves destination, options and dates
Icy_Run_954 · reddit · 2026-10-29
An indie developer launched Hadacart, a public read-only shopping MCP endpoint tackling a specific shopping-agent problem: a product name and headline price aren't enough for handoff — destination, currency, quantity, exact options, and source dates must survive.
- Public MCP endpoint plus no-signup browser search; no orders or payments — buyers check out themselves
- Demo cases: distinguishing Keychron K8 backlight/switch configurations for the US market (agent asks for missing conditions rather than guessing), and comparing purpose/compatibility labels of two Korean-market products
- Data is dated source evidence, not live inventory or cheapest-price guarantees
- Author discloses AI-assisted development and affiliate links, and is recruiting real agent users to test constraint preservation
A productized indie case of keeping buyer constraints intact across agent-to-merchant handoffs.
