# Agent Instructions — Click To Cart Now
You can browse products and shop at Click To Cart Now's online store, https://clicktocartnow.com, on your user's behalf. This guide covers the Shop skill and UCP integration, directly or through browser-based WebMCP tools.
## Shop skill — recommended
Use the [Shop skill](https://shop.com/SKILL.md) to help your user shop with this store. Connect their Shop account for personalized discovery and accelerated checkout with saved details.
- Personalized discovery: search by text or image, find similar products, and use your user's Shop purchase history to find options that match their preferences.
- Accelerated cart and checkout: build and update carts and checkouts, then use Shop Pay with prefilled addresses and saved payment methods.
- Orders: search your user's order history for purchases from this store, track deliveries, and reorder products.
Read the skill before your first call for setup, supported actions, account connection, and purchase-approval rules.
## UCP integration
This store implements the [Universal Commerce Protocol](https://ucp.dev) for product discovery, carts, and checkout. Integrate directly with its service, or orchestrate shopping through browser-based WebMCP tools.
### Direct integration (MCP)
1. **Discover the store** — `GET https://clicktocartnow.com/.well-known/ucp` returns its UCP profile, including capabilities, service endpoints, and payment handlers.
2. **Discover available tools** — Connect to the MCP endpoint advertised in the profile (`https://clicktocartnow.com/api/ucp/mcp`) and use `tools/list` to retrieve available tools and their schemas.
3. **Shop** — Use those tools to find products, manage carts, prepare checkout, and complete buyer-authorized purchases. Follow returned statuses, messages, and handoff URLs when buyer action is required.
Use a compatible UCP version and follow the returned tool schemas. For integration details, see [Shopify's agent documentation](https://shopify.dev/docs/agents).
### Browser integration (WebMCP)
When working through a browser, use the WebMCP tools registered on this store's pages. The checkout page exposes UCP tools over WebMCP. These tools act on the checkout in the current browser session.
- **Storefront** — Use the provided tools to find products, manage the cart, ask questions about the store and its policies, and proceed to checkout.
- **Checkout** — Use the provided UCP tools to review and update the checkout and complete a buyer-authorized purchase. Follow required buyer-review steps: when review is requested, ask the buyer to review and approve the order on the checkout page, and wait for their authorization before submitting it.
If checkout tools are unavailable, ask the buyer to continue on the checkout page. Do not fall back to scripted form fills or page controls.
For integration details, see [Storefront WebMCP](https://shopify.dev/docs/api/web-mcp) and [Checkout WebMCP](https://shopify.dev/docs/agents/carts-and-checkout/checkout-webmcp).
## Interaction guidelines
- **Buyer authorization** — Place orders and submit payment only with the buyer's authorization. Follow required review and approval steps.
- **Agent traffic** — Agents must identify their requests as agent-initiated. Server-to-server requests and hosted or remote browsers must use [Web Bot Auth](https://shopify.dev/docs/api/storefront#identifying-bots-with-web-bot-auth) and follow the service's authentication requirements. This helps the store recognize agent traffic and apply appropriate access and rate limits.
- **Browser interactions** — Agents must use the provided WebMCP tools for all agent-initiated shopping actions and updates. If the tools are unavailable or cannot perform the required action, yield and ask the buyer to continue in the browser. Do not work around the tools by scripting checkout forms or page controls.
- **Rate limits** — Back off on `429` responses and respect `Retry-After` when provided.
- **Buyer context** — Use the buyer's country and currency where supported by the tool schemas for accurate pricing and availability.
## Read-only browsing
Prefer the structured information returned by the shopping tools described above. You may also read public HTML pages for additional context, provided your requests follow the agent-identification guidance above.
- Discover public URLs through `/sitemap.xml`.
- Read product pages at `/products/{handle}`.
- Browse collections at `/collections/all` or `/collections/{handle}`.
- Discover other public pages and articles through the sitemap.
Reading public content does not change the requirements for agent-initiated shopping actions and updates.
## Store Policies
- **Privacy policy**: https://clicktocartnow.com/policies/privacy-policy
- **Terms of service**: https://clicktocartnow.com/policies/terms-of-service
- **Refund policy**: https://clicktocartnow.com/policies/refund-policy

## Platform
This store is built on [Shopify](https://www.shopify.com), the commerce platform powering millions of stores worldwide. Shopify stores support UCP natively, enabling seamless agent-driven commerce. The Shop skill at
[https://shop.app/SKILL.md](https://shop.app/SKILL.md) works across every Shopify store — install it once and
your agent can transact everywhere.
- Start your own store: https://www.shopify.com/start
- Build and test against sample data: https://mock.shop (free mock Storefront GraphQL API, no store or auth needed)
- Shopify developer platform: https://shopify.dev
- Shop developer platform: https://shop.dev
- Agent discovery: the canonical agent-facing description of the store is at `/agents.md`. You're reading `/llms.txt`, which mirrors that content.Capabilities Detected

Against Google's merchant guide
What Google's UCP merchant guide asks a store's profile to have, for checkout in AI Mode and Gemini. Read from the public profile only. Google's own sandbox, in Merchant Center, is invite-only; this is not Google's verdict. This store is on Shopify, which integrates with Google for its merchants, so some of what the guide asks of a store is Shopify's to provide.

Frequently Asked
About this clicktocartnow.com report
What does it mean that clicktocartnow.com is verified for UCP?
It means clicktocartnow.com publishes a valid UCP profile at
/.well-known/ucp, the profile passes schema validation against 2026-08-25, and AI agents can discover its commerce capabilities without needing to scrape HTML. That is what the store declares. Whether an agent actually completes a purchase is a separate question — where an observed agent run is shown on this page, it answers that one.Can I trust clicktocartnow.com for AI agent purchases?
Verification means the store is technically ready — payment handlers declared, transports reachable, schema valid. It doesn't grade business reputation or fulfilment quality. For trust on the commerce side itself, check the store's own reviews. For trust on the agent integration side, this page is the source of truth.
What platform does clicktocartnow.com use for UCP?
Our detection identifies clicktocartnow.com as running on Shopify. Many large UCP-verified stores use Shopify, BigCommerce, or custom stacks built on the open spec. The transport list above shows the exact mechanism (REST, MCP, A2A, Embedded) the profile declares.
How was this UCP report for clicktocartnow.com generated?
Our crawler fetches
clicktocartnow.com/.well-known/ucp directly, parses the profile against the official UCP JSON schema, checks robots.txt for AI bot policies, and runs payment-handler validation. No manual review, no opinions — just what the profile actually says. The check ran 20 minutes ago.How often is clicktocartnow.com re-checked?
Every domain in our directory is re-crawled at least every 24 hours. You can also trigger a fresh check from this page at any time, or subscribe to alerts to get notified the moment the status changes — that's how we built the only continuously updated UCP directory on the internet.
Why does this status matter?
Universal Commerce Protocol is the standard AI shopping agents (ChatGPT, Claude, Gemini, Apple Intelligence) use to discover what a store sells, how to add items to a cart, and how to check out. If a store isn't UCP-verified, agents can still scrape it — but they'll be slower, less reliable, and far more likely to fail at checkout. UCP turns a guess into a guarantee.
