Implement the UCP Catalog capability (`dev.ucp.shopping.catalog`) — free-text product Search and identifier-based Lookup, the Product/Variant data model, media, ratings, and quantity units. Use when exposing product discovery to agents or consuming a business catalog before cart and checkout.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# UCP Catalog Capability ## Before writing code **Fetch live spec**: Web-search `site:ucp.dev specification shopping catalog` and fetch the capability page plus its `search` and `lookup` operation pages. The Product/Variant schema and filter vocabulary evolve between spec versions — read the live schema before writing types. ## Conceptual Architecture ### What Catalog is for Catalog is the **discovery** half of UCP, upstream of Cart and Checkout. It covers free-text product search, category and filter-based browsing, batch retrieval by identifier, and price comparison across variants. Without it, an agent can only transact against items it already knows the IDs for. ### Two operations | Operation | Namespace | Purpose | |-----------|-----------|---------| | Search | `dev.ucp.shopping.catalog.search` | Locate products by query text and filters | | Lookup | `dev.ucp.shopping.catalog.lookup` | Retrieve specific products or variants by identifier | Search is for *finding*; Lookup is for *resolving*. An agent typically searches once and then looks up identifiers it has cached or received from elsewhere (a permalink, a previous cart). …

How to install
mdr add orcaqubits/agentic-commerce-skills-plugins/ucp-catalog@sha256:d8797be40f3fbb5cThe line at the top of this page pins the label git:20260914.08f85a3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
