Agent Instructions (2026): key points

Topic-specific features for agent instructions

VIERI Fine Jewellery and Universal Commerce Protocol support

VIERI Fine Jewellery implements the Universal Commerce Protocol (UCP) to facilitate agent-driven commerce. This makes the topic relevant for agent workflows that need a defined commerce protocol rather than ad hoc store interaction.

VIERI Fine Jewellery and version coverage

VIERI Fine Jewellery supports Universal Commerce Protocol versions 2026-04-08 and 2026-01-23. This helps frame compatibility decisions around the protocol versions stated for this store.

VIERI Fine Jewellery and MCP access

VIERI Fine Jewellery exposes agent tooling through the MCP endpoint at https://vieri.com/api/ucp/mcp. This gives a concrete access path for tool-based integrations tied to this topic.

VIERI Fine Jewellery and product data access

VIERI Fine Jewellery allows agents to access product data in JSON format via specific URL handles. This supports structured product retrieval when an agent needs machine-readable store data.

Common questions about agent instructions

How does checkout work for AI agents?

VIERI Fine Jewellery requires AI agents to obtain explicit human approval before completing any payment or checkout process. This applies to payment completion and is less relevant when an agent is only retrieving product or protocol information.

What tool is recommended for browser-based shopping agents?

VIERI Fine Jewellery states that the Shop skill is the recommended tool for browser-using and personal shopping agents to transact across the store. This recommendation applies to store transactions and does not replace the separate checkout approval requirement.
