Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

check_domainread-onlyBefore acting on a website for a user, check whether it lets AI agents browse, shop, book or log in, and whether there's an official agent route (UCP, ACP, MCP, Visa TAP, A2A, partner apps). Returns status (open|partial|announced|none, or unknown if we have no verified record), recommended_action (a suggestion based on public sources, not permission; the website's own terms always take priority), per-action allowances, routes, dated sources. Read-only.
check_domainsread-onlyBatch version of check_domain for up to 50 domains or URLs. Results are returned in input order. Read-only.
report_blockDeprecated alias kept for older clients. Same as submit_update with type report_block (or report_works when result is works / official_route_found). Goes to human review; nothing auto-publishes.
submit_updateSuggest a change to the database: add a brand (add_brand), correct a listing (correct_listing), report that an agent was stopped on a site (report_block), or report that a task now works (report_works). Every submission goes to a human review queue; nothing is published automatically, and a listing only changes once it is verified from a brand statement or official docs, reputable reporting, or our own documented test. Do not include personal data about the user.
