Tanatasa lets AI assistants do the shopping in Singapore: 42,000 products via MCP, API and ChatGPT plugin

Singapore retailer Tanatasa has opened its store to the personal AI assistants themselves. In a press release dated October 31, 2026, the company said it had launched what it calls Singapore’s first agent-first e-commerce store: instead of a shopper browsing listings and filling a cart, a customer tells an assistant what is needed and the assistant does the searching, comparing and cart-building — stopping for the shopper’s approval before anything is bought.

“We don’t want to build yet another AI shopping assistant. Consumers already have their own agents, and those agents increasingly understand their preferences, budgets and shopping habits,” said Li Sian, founder of tanatasa.SG. “Our job is to make sure those agents can actually shop, not just tell people what they should buy.”

What the agents can actually do#

The release sketches the experience with a household restock: “Help me restock the house. I need rice, cooking oil, laundry detergent, toothpaste and some snacks for the kids. Keep it under S$60 and show me the cart before buying.” Through Tanatasa’s shopping infrastructure, the company says, a compatible agent can find suitable products, compare options, check prices and stock, select quantities, apply discount codes, build a shopping cart and prepare checkout for the customer’s approval. The shopper can review the proposed basket, request changes and approve the purchase through a secure checkout. No Tanatasa account is required, and delivery is free across Singapore during the launch period, with no minimum order. Shared shopping carts let a customer move between the browser and a connected agent.

The catalogue, as described in the release, holds more than 42,000 products across groceries, household essentials, beauty, personal care, health and wellness, baby products and pet supplies. Tanatasa says it has already fulfilled more than 10,000 customer orders and is expanding from its beauty and wellness roots into a broader destination for everyday essentials, with agent-first commerce at the centre of its strategy.

How it connects: MCP, REST, CLI and a ChatGPT plugin#

The store is built to be used without a website visit. Its infrastructure supports Model Context Protocol (MCP), REST APIs and CLI command-line tools, the release says, letting compatible agents interact directly with the product catalogue and shopping functions. Tanatasa is also available as a ChatGPT plugin. The platform is designed to work with personal AI assistants including Meta Muse, OpenAI Dots, Instinct and Claude Duet, as well as other agents able to connect to its shopping interfaces.

Tanatasa’s live agent documentation backs up the plumbing: public MCP and REST endpoints, catalogue search and product details with no account or token, guest carts and checkout with no login, and one versioned cart shared by the shopper and the agent. Payment is approval-first, through a hosted Stripe page after the buyer reviews the total. The documentation says the full MCP endpoint advertises sixteen tools. It also carries a useful caution: these are supported shopping instructions, “not a claim that every host has an approved native connector or verified end-to-end checkout” — so the experience may vary by assistant.

Why now: a wave of personal agents#

The timing, as the release tells it, follows a run of personal-agent launches: OpenAI introduced Dots on September 29, Instinct has gained traction since its August debut, and Meta brought Muse to Singapore on October 27, with shopping among its key capabilities. The pitch is that these assistants promise to carry out tasks on a user’s behalf, not just answer questions — and that retailers will increasingly have to serve the agents as well as the humans. Li Sian put it as a shift in competition: retailers have competed to attract people to websites and apps, but if consumers start asking their agents to shop, those agents will need stores they can actually transact with. “Tanatasa is the first place the AI agents can go to for shopping in Singapore,” the release quotes Li Sian as saying.

What to watch#

The “first” claim is the company’s own, and the release is the evidence for it so far — there is no independent test of the store in the announcement. The more interesting test is operational: whether assistants complete real baskets reliably, whether shoppers trust the approval step, and whether the catalogue lives up to the release’s breadth. The agent-docs page itself still describes beauty and wellness products in places, so shoppers should check the live catalogue for the categories they need. Free delivery is a launch-period offer, not a permanent promise, and the documentation advises rechecking prices and stock before checkout, noting that stock is not reserved. If agent-first shopping works here, the model to watch is not the novelty of an agent browsing a store — it is a store built so an agent never has to browse at all.
