# Cortinas Roller Santiago | Envío Express 24-48 hrs | Clems
> Cortinas roller blackout, dúo zebra, sunscreen y doble, listas para instalar. Envío 24-48 h hábiles en Santiago, gratis sobre $50.000 en RM, y a todo Chile. This is a Jumpseller-powered online store. Agents can browse its public content via the sitemap or access structured product and category data through the MCP (Model Context Protocol) endpoint. No authentication required.
This document is also available at [https://clems.cl/agents.md](https://clems.cl/agents.md).
## MCP (Model Context Protocol)
- [MCP endpoint](https://clems.cl/api/mcp): send JSON-RPC 2.0 requests via POST (Streamable HTTP)
- [MCP discovery](https://clems.cl/.well-known/mcp.json): server metadata and capabilities
### Available Tools
- get_store_info: Get public store information including name, URL, country, currency, description, and logo.
- search_policies: Search the store's own pages - returns, terms, privacy, shipping, FAQ - and return the ones that answer a question, with their text. Called with no query it returns the store's legal pages. Results are ordered with those first: a page marked "legal": true is the store's own terms and can be quoted as policy, and anything else is a page the merchant wrote, which may answer the question but is not a policy.
- list_products: List available products in the store. Returns name, price, images, variants, and categories. Supports pagination and filtering by category permalink.
- get_product: Get a product by the id this server returns, or by its permalink (URL slug). Returns name, price, description, images, variants, and categories.
- search_products: Search products by query string. Searches in name, description, and SKU. Only returns available products.
- list_categories: List product categories visible in the store navigation.
- get_category: Get a category by permalink (URL slug). Returns name, description, SEO fields, and images.
The MCP endpoint is the recommended way to access structured product and category data.
## Universal Commerce Protocol (UCP)
- [UCP profile](https://clems.cl/.well-known/ucp): advertised capabilities and their endpoints
- [Shopping endpoint](https://clems.cl/api/ucp/mcp): the Catalog and Cart capabilities over UCP's MCP binding
### UCP Tools
- search_catalog: UCP Catalog search. Returns products matching a query, in the UCP Product shape.
- lookup_catalog: UCP Catalog lookup. Returns the products with the given ids, in the UCP Product shape.
- get_product: UCP Catalog detail. Returns one product by id, in the UCP Product shape.
- create_cart: UCP Cart create. Builds a cart from variant ids returned by the catalog and returns it with estimated totals and a continue_url the shopper can be handed to finish the purchase. Prices are integers in the currency's ISO 4217 minor unit: 9500 EUR is 95.00.
- get_cart: UCP Cart read. Returns the cart's current line items, estimated totals and continue_url. Prices are integers in the currency's ISO 4217 minor unit: 9500 EUR is 95.00.
- update_cart: UCP Cart update. Replaces the cart's line items with the ones sent: send every line the cart should hold afterwards, not only the ones that changed. An empty list empties the cart.
- cancel_cart: UCP Cart cancel. Empties and closes the cart, and returns the state it was in before that. Later calls for the same id report it as not found.
## Read-Only Browsing (No Authentication Required)
For agents that only need to read public store data without using the MCP endpoint:
- [Sitemap](https://clems.cl/sitemap.xml): all public product, category, and content pages ([robots.txt](https://clems.cl/robots.txt) lists the paginated sitemap files)
- [Search](https://clems.cl/search?q={query}): full-text product search (HTML)
- Product, category, and content pages are served as HTML at https://clems.cl/{permalink}
## Platform
This store is built on [Jumpseller](https://jumpseller.com), an e-commerce platform. All Jumpseller stores expose the same MCP endpoint and tools. See the [Jumpseller AI Toolkit](https://jumpseller.com/support/ai-toolkit/) for more information.
