Registry code: de77e916114fb4bb

Agent-to-Agent (A2A) + Model Context Protocol (MCP) hub for cosmetics. Business to business: brands, manufacturers, retailers, distributors and their AI agents (GreenCore Solutions Corp.). Call resolve_jurisdiction, then resolve_actor, then gate_transaction before any availability, price, documents, order or handoff tool; those tools refuse without an allow decision. Eighteen markets on thirteen rule sets; every record field carries its source page; every response carries notice; every record carries claim_status (listed · claimed · verified). Artificial intelligence makes mistakes. A2A…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

resolve_jurisdiction unknown never probed
Where is this going? Resolve a ship-to (e.g. 'US', 'US-CA', 'UK', 'FR', 'EU-DE', 'JP') to one of the 18 markets and its rule set (13 rule sets; the six EU markets share one). UK is the label; machine fields carry the ISO code GB.

arguments 11 lines
resolve_actor unknown never probed
Who is asking? Brand, manufacturer, retailer or distributor (business to business); auditor (read-only); agent (inherits the class of the credential it presents — none returns DENY_UNLICENSED_AGENT). The consumer is never the counterparty. Returns communication_class: trade_information or public.

arguments 22 lines

gate_transaction unknown never probed

Allow or deny, with the reason and the rule. Takes a product (GTIN or catalogue id; optional), the ship-to market, the actor class and, when no record exists yet, the product type, ingredients (INCI) and claims. Returns one of twelve reason codes (ALLOW · REQUIRE_NOTIFICATION · REQUIRE_RESPONSIBLE_PERSON · DENY_NOT_A_COSMETIC_HERE · DENY_INGREDIENT_BANNED · DENY_INGREDIENT_LIMIT · DENY_CLAIM · DENY_MARKET · DENY_ACTOR_CLASS · DENY_UNLICENSED_AGENT · DENY_NO_GTIN · DENY_NOT_VERIFIED), the rule-set version, the source page and a decision_id for the downstream tools.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/de77e916114fb4bb/badge.svg)](https://brick.blue/agent/de77e916114fb4bb)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
