# Agent Instructions — Mirasvit Magento Extensions Store

This store supports AI-driven catalogue discovery over the Universal Commerce Protocol (UCP).

## Commerce Protocol (UCP)
- [UCP Discovery](https://mirasvit.com/.well-known/ucp) — GET, merchant profile: versions, capabilities
- [MCP endpoint](https://mirasvit.com/agent/mcp) — POST, Content-Type: application/json

### Typical agent flow (v1)
1. Discover  — GET /.well-known/ucp
2. Search    — search_catalog
3. Inspect   — get_product / lookup_catalog
4. Cart      — create_cart, then give the shopper the returned continue_url to review and complete
(The agent builds the cart; the shopper completes checkout in the browser — checkout requires human approval.)

### Supported UCP versions
- 2026-04-08 (latest stable)
- 2026-01-23

### Rules
- Pass context.address_country and context.currency for accurate pricing/availability.
- Respect rate limits; back off on 429.
- Checkout requires human approval. Do not complete payment without explicit buyer consent.

## Read-Only Browsing (No Authentication Required)
The store serves these JSON endpoints itself (no auth, no GraphQL dependency):
- [Products / search](https://mirasvit.com/agent/products.json?q={query}&page={n}) — GET
- [Single product](https://mirasvit.com/agent/products/{url_key}.json) — GET
- [Category products](https://mirasvit.com/agent/collections/{url_key}/products.json) — GET
- [Sitemap](https://mirasvit.com/sitemap.xml) — GET
- Agent discovery — /agents.md (canonical) and /llms.txt (mirror), plus /.well-known/ucp

Questions

Can UCP agents buy from mirasvit.com?
Through its MCP service, an agent can search the catalogue and build a cart. The service answered our check. This is what the store declares and what our check reached; an observed agent run shows how far an agent actually gets.
Is mirasvit.com ready for UCP agents?
mirasvit.com publishes a valid UCP profile and scores 86/100 (grade A). 4 things to fix: the profile isn't served with the caching the spec requires, the profile has no ETag or Last-Modified header, move to the latest UCP protocol version and publish a sitemap.xml.
What is a UCP profile?
The JSON file a store publishes at /.well-known/ucp to tell UCP agents which services it offers, how to call them and how it takes payment. The spec calls it the business profile. mirasvit.com's is 2.0 KB, written for UCP 2026-04-08. What goes in a UCP profile.
How was mirasvit.com checked?
With public requests on 17 Oct 2026: we read /.well-known/ucp and robots.txt, validated the profile against UCP 2026-04-08, checked that its spec and schema links resolve, and called its MCP service. No sign-in and no purchase. How we check.
