A human-approval gate between an AI assistant and your Amazon cart. An assistant (like Claude) drafts a project's parts list and encodes it into a link; this page shows you every item — with the reasoning — so you decide what's actually bought. Checkout happens on Amazon, by you.
Ask your assistant to read llms.txt, or build a link yourself:
payload = {
"project": "Raised garden bed",
"items": [
{"name": "Cedar fence pickets 6ft (8-pack)", "qty": 2,
"why": "Rot-resistant walls for a 4x8 bed",
"search": "cedar fence picket 6 ft",
"est": 45.0},
{"name": "Exterior wood screws #10 3in, 1 lb", "qty": 1,
"search": "exterior deck screws 3 inch", "est": 12.0,
"asin": "B000BQY3O2"}
]
}
url = "https://jeddoman.com/kitlist/#d=" +
base64url(gzip(json(payload)))
Items with a real asin link straight to their product page (one tap to add in the Amazon app); everything else gets a search link. There's a ready-made Python builder and an MCP server in the repo.
Kitlist is a free tool that lets an AI agent — Claude, ChatGPT, or any assistant that can follow llms.txt or call an MCP tool — turn a project into an Amazon shopping list that a human reviews and approves before anything is bought. The agent proposes items with reasoning and quantities; the person unchecks what they don't want and completes checkout on Amazon themselves. It is a human-in-the-loop approval gate for agentic commerce: the agent can never spend money.
Two ways. Simplest: read llms.txt and build a link — the whole list is gzip+base64url-encoded in the URL fragment, so no API key, no signup, and nothing is sent to a server. Or install the MCP server from the GitHub repo and call the tool create_shopping_list(project, items), which returns a review URL to hand to the user.
No — by design. Kitlist implements the proposal-and-approval half of agentic commerce: the agent drafts, the human decides, and Amazon's own cart and checkout remain the final step. Verified items open as real Amazon product pages, one tap per item; everything else gets a search link so the human picks the exact product.
Any task that ends in "things to buy": DIY project materials, recipe ingredients, camping or newborn checklists, first-apartment kits, repair parts, event supplies. Ask your assistant to plan the project and "make me a Kitlist" — then approve the result here.
