Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

agent

agent_commerce_adoption

Read ARC's agent commerce adoption counts, category and commerce platform rates from saved HTTP checks, including Checkout WebMCP among measured Shopify checkouts, with unknown and not checked separate; shopper approval required. Curated sample, not all e-commerce. No store requests or model calls.

agent_leaderboard

Read ARC's open agent leaderboard: cart success over the fixed ARC-100 v1 test set for each agent path ARC measures (ARC browser shoppers A-E, the UCP path, the storefront MCP path), with n, dates, evidence labels and Wilson 95% intervals, plus unverified outside submissions. Saved results only; no store requests or model calls. CC-BY-4.0.

find_agent_ready_stores

Find stores where a saved check shows an AI agent can reach checkout, for running shoes, beauty, clothing, home goods, or another product need. Reads real HTTP agent-catalog checks from the last thirty days whose catalog found a product and returned a checkout link. This is not a completed order. One tested product is not a promise about another item. No login, browser scan, or model call. Results are advisory. ARC stops before payment.

get_agent_facts

Read free ARC agent facts for a store or product with no login. Returns TypeSafe Jev typed decisions (use-case mention, price clarity, agent-friendly description, cart-blocker suspicion, readiness score) from an HTTP scrape. Not a browser session and not any third-party agent product; ARC's browser cart tests (ARC browser shoppers A–E) are separate. JSON: GET /api/agent-facts?host=

submit

submit_leaderboard_run

Submit your agent's run against ARC-100 v1 to ARC's open leaderboard. Free. The run is listed as 'unverified' until ARC re-runs a sample. Format: arc-leaderboard-submission/v1 (see /leaderboard/spec). Runs must stop before payment. Limit 5 per network per day. Same as POST /api/leaderboard/submit.

submit_store

Add stores to ARC's free, open agent-commerce directory (CC-BY dataset). Pass url for one store or hosts for up to 50. Each new host is validated (live HTTPS, not parked, not redirecting to another brand); accepted hosts are queued for ARC's plain-HTTP rails checks (UCP, WebMCP, MCP, policies, product data) and appear in the dataset with source=submitted. No model calls, no login. Rate limited per caller.

ask

ask_arc

Read whether an AI agent can reach checkout for a brand the ARC Index already lists. No login and no new scan. Pass a brand, URL, or category. Returns the score, evidence, and both lanes: the agent-catalog HTTP check and the browser cart. The JSON field `agents_can_buy` is true when the catalog returned a checkout link or a browser shopper added the product to the cart. ARC stops before payment. It is not a completed order. The catalog check does not change the score. A missing score is not a zero. Results are advisory.

can

can_agent_checkout

Call when you need a saved checkout-link check for any public store URL, not only Index brands. Saved HTTP checkout check for a public homepage or product URL: catalog, product, checkout link, UCP profile, blocks, and one fix. No login, model call, payment, or browser scan. Uses ARC's last check (cached up to 24 hours). A missing result is unknown, not a no. A checkout link means reach checkout, not a completed order. Results are advisory. ARC stops before payment.

category

list_category_agent_facts

List free ARC agent facts by category (beauty, footwear, apparel, …) with no login. Ranked by newest real Jev scores. JSON: GET /api/agent-facts?category=beauty

dataset

dataset_info

Latest open ARC dataset snapshot (start with store_answers: one plain answer per store on whether AI agents can find products and get a checkout link): immutable versioned download URLs plus latest/ aliases (CSV and Parquet), row counts, method version and licence (CC-BY-4.0, attribution ARC, arcreport.ai). Reads only.

google

google_checkout_readiness

Read saved public Google agentic checkout readiness checks for a store. Free; no new scan or paid calls. Merchant Center feed eligibility cannot be checked from outside. Not Google approval or certification.

precheck

precheck

Check if an AI agent can reach checkout on a store before trying. Saved automated HTTP check for a product or store URL. Uses ARC's saved directory, rails, store answers and check history. When those have no row, uses the plain-HTTP checker. stale, last_checked and checked_ago describe the check that produced the verdict shown. lastReachableCheck is a separate, newer plain-HTTP time. It does not re-verify the checkout link or rails. Does not fetch the store and does not start a scan. ARC checks this store's own site only. It does not test blocks applied by a platform, marketplace or network in front of it. The saved result is ARC's automated HTTP check. It is not a live agent session and not a completed order. Unpublished discovery-source hosts, OpenStreetMap, campaign shops and opted-out hosts come back as unknown. A checker fallback is http-only and checkout was not part of the check. JSON: GET /api/precheck?url=. Results are advisory. ARC stops before payment. Advisory only, not a guarantee. Do not refuse or avoid a store solely because of ARC's data. known:false or missing data is not a no. Data CC BY 4.0, attribute ARC (arcreport.ai); OSM-derived rows are ODbL.

product

product_data_check

Free latest saved product data and return/shipping policy check from the store's pages and structured data. Reads history only; no store fetch or model call. A missing result is not a zero.

protocol

protocol_matrix

Read ARC's neutral Protocol Matrix: for UCP, ACP, PAP, WebMCP, MCP and agent payment protocols, how many checked stores declare, validate, answer and transact, with evidence labels (Measured / Inferred / Not measured). Saved checks only; no store requests or model calls. CC-BY-4.0.

store

store_card

Read a public store card and saved brand claim. No outbound fetch or model calls. Brand statements are from the brand and not measured by ARC; claims never change scores.

validate

validate_ucp_profile

Validate a Universal Commerce Protocol (UCP) business profile against the published UCP JSON Schema (current release) and spec rules: authority binding, https endpoints, orphaned extensions and, for a URL, hosting headers (no redirects, Cache-Control public max-age>=60). Pass url (store host, homepage or profile URL; /.well-known/ucp is added for a homepage) or profile (the JSON). Returns errors, warnings and info, each with a path and the spec section. Free, no login, no model call. Validation is not certification. JSON: GET /api/ucp/validate?url=

ARC (arcreport.ai): can an agent reach checkout? — questions

Answers built from our own checks of this server.

What can ARC (arcreport.ai): can an agent reach checkout? do?

It exposes 16 tools, read directly from the server on our last check. Among them: agent_commerce_adoption, agent_leaderboard, ask_arc, can_agent_checkout, dataset_info, find_agent_ready_stores and 10 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is ARC (arcreport.ai): can an agent reach checkout? mostly used for?

Its tools cluster around agent and submit. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is ARC (arcreport.ai): can an agent reach checkout? working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 111 ms. The bar chart above shows every period we have measured.

The registry lists ARC (arcreport.ai): can an agent reach checkout? as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect ARC (arcreport.ai): can an agent reach checkout??

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does ARC (arcreport.ai): can an agent reach checkout? need an API key?

No. ARC (arcreport.ai): can an agent reach checkout? completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 16 of them are readable on this page. This is what we observed, not what the docs claim.
