Overview

AI-generated overview

Remote MCP server that lets an assistant check whether AI agents can reach checkout on online stores, using ARC's saved HTTP checks and open datasets.

What you can do
  • Check agent checkout readiness for a store or product URL, or ask about a brand in the ARC Index, with score, evidence and both the catalog and browser lanes
  • Find agent-ready stores by product category and read per-category agent facts and store cards
  • Read saved product data, return and shipping policy checks, and Google agentic checkout readiness
  • Query open datasets: adoption counts, the Protocol Matrix for UCP, ACP, PAP, WebMCP, MCP and payment protocols, and the agent leaderboard
  • Validate a UCP business profile against the published JSON Schema and spec rules
  • Submit a store to the directory or submit an agent run to the leaderboard
When to use it
Useful when evaluating whether a store is reachable by AI shopping agents, comparing agent checkout performance, or pulling ARC's open agent-commerce datasets and protocol statistics. Also handy for validating a UCP profile or adding stores to the directory.
Requirements
Remote streamable HTTP endpoint at arcreport.ai; no authentication, environment variables or headers declared. Most tools read saved checks and datasets, so no store-side setup is needed.
Before you install
Results are advisory and based on saved HTTP checks, not completed orders; a missing result is not a zero, and brand claims are not measured by ARC. Submitting a store or leaderboard run writes data to ARC's public directory and leaderboard, with runs listed as unverified and a limit of five per network per day. Runs must stop before payment.

Installation

In SourceWeft

  1. Open ARC (arcreport.ai): can an agent reach checkout? in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.arcreport%2Fask/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

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.

Parametersurlrequired

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.

Parametersqlimitcategory

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.

Parametersurlrequired

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.

Parametersqurlbrandcategory

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.

Takes no parameters.

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.

Parametersurlhost

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.

Parametershostrequired

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=

Parametersurlhostslug

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

Parameterslimitcategory

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.

Takes no parameters.

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.

Parametersprotocol

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.

Parametersinclude_stores

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.

Parametersrunrequiredspecrequiredagentrequiredcontactresultsrequiredtest_setrequired

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.

Parametersurlhostscategory

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.

Parametershostrequired

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=
