Common questions

Is ARC: agent checkout reachability safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.2.0) reached the registry 24 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

ARC: Agentic Report Card

ARC is the free, neutral record of which online stores AI agents can actually reach checkout at, with dated evidence.

Website: https://www.arcreport.ai

This repo holds ARC's public MCP connector metadata and setup instructions. ARC is a hosted service, so there is nothing to install or run.

Quick start: precheck (free, no sign-in, CC BY 4.0)

Before your agent tries a store, ask ARC whether agents can reach checkout there:

curl "https://www.arcreport.ai/api/precheck?url=https://allbirds.com"

Real response (trimmed, 14 Oct 2026):

{"host":"allbirds.com","known":true,"reachable_checkout":true,

"rails":[{"name":"UCP","status":"valid"},{"name":"ACP","status":"not_found"}, {"name":"MCP","status":"yes"},{"name":"Checkout WebMCP","status":"detected"}], "blockers":[],"confidence":"high","last_checked":"2026-10-13T09:47:13.000Z", "stale":true,"source":"ARC (arcreport.ai)","licence":"CC BY 4.0"}

reachable_checkout is based on ARC's last saved check. It does not mean an agent completed checkout. Check last_checked and stale before relying on it. Contact: arcreport@mail.grokbot.com (ARC).

Advisory only, not a guarantee. Missing data or known:false is not a no.

Endpoints

What	URL	Registry name
MCP connector (store checks)	`https://www.arcreport.ai/api/mcp`	`ai.arcreport/mcp`
Ask connector (stores, protocols, submissions)	`https://www.arcreport.ai/api/ask`	`ai.arcreport/ask`

Both use the Streamable HTTP transport and are listed in the official MCP Registry. Reading saved checks (check_store, find_stores) and reporting a checkout attempt (report_checkout) need no sign-in.

How ARC reports results

Every result is dated and labelled by source: agent-reported, ARC-tested up to payment, or a verified order. A missing result never counts against a store.
