What this MCP does

Checks cosmetic products and ingredients across markets, including regulatory status, labeling, claims, safety documents, availability, pricing, and verified suppliers.

a2a_handoff
A2A Handoff
Hand the buyer to the right agent over Agent-to-Agent (A2A): with an allow decision the order intent goes to the counterparty's agent (envelope + card URL); with a deny, the market agent of the ship-to (the regulator's home page beside it) — a referral, never a sale to a consumer.
Input schema
{'type': 'object', 'properties': {'intent_id': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None}, 'decision_id': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None}, 'counterparty_card_url': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None}}}
Output schema
{'type': 'object'}
compare_items
Compare Items
Compare products, variants and shades side by side (two to eight GTINs or catalogue ids).
Read only Idempotent
Input schema
{'type': 'object', 'required': ['gtins'], 'properties': {'gtins': {'type': 'array', 'items': {'type': 'string'}}, 'market': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None}, 'decision_id': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None}}}
Output schema
{'type': 'object'}
create_order_intent
Create Order Intent
Open an order between two agents: an order intent for a cleared product after the gate; the intent carries reason_code + rule_set_version and settles by x402 on a2a-x402.ai.
Input schema
{'type': 'object', 'required': ['gtin', 'quantity', 'decision_id'], 'properties': {'gtin': {'type': 'string'}, 'market': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None}, 'ship_to': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None}, 'quantity': {'type': 'integer'}, 'decision_id': {'type': 'string'}}}
Output schema
{'type': 'object'}
find_verified_supplier
Find Verified Supplier
Verified makers and brands for this product or product type in a market: supplier records (brand · manufacturer) with their claim status — verified first, then claimed, then listed. Takes the decision_id of an allow decision.

Output schema
{'type': 'object'}
gate_transaction
Gate Transaction
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.

Read only Idempotent
Input schema
{'type': 'object', 'required': ['ingredient'], 'properties': {'ingredient': {'type': 'string'}}}
Output schema
{'type': 'object'}

get_label_and_claims

resolve_actor
Resolve Actor
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.
