What is ucp-agentic-commerce?

A guide to the Universal Commerce Protocol, a set of rules for letting software agents discover stores and handle commerce tasks. It covers connections over REST, MCP, A2A, and embedded interfaces.

Use it to build agent-accessible commerce flows, including product discovery, checkout, order handling, payments, fulfillment, and discounts.

It helps developers represent discovery, checkout, orders, payments, delivery, discounts, and identity linking in a consistent protocol. This reduces the work of designing separate agent-facing integrations for each commerce action.

Security

Grade A, and why

ucp-agentic-commerce scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads gemini-extension.json. This mod also ships 17 executable files (scripts/check_links.mjs, scripts/check_secrets.py, scripts/convert.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
