A2A Peptides MCP server

• a2a_handoffFree

  Hand off over Agent-to-Agent (A2A). With an allow/require_rx decision: the order intent goes to the licensed counterparty's agent (envelope + card URL). With a deny for a patient, the public or an unauthorized actor: returns real licensed destinations from the provider directory (dispensers, prescribers) filtered by the decision's jurisdiction, state/province and practice scope — a referral, never a vial.

• compare_presentationsFree

  Compare two or more authorised presentations side by side (ids as for get_item).

• create_order_intentwrite actionFree

  Create an order intent for a cleared item after the gate; the intent carries reason_code + rule_set_version and settles by x402 on peptides-x402.ai.

• find_licensed_supplierFree

  Licensed parties for a presentation in a jurisdiction (tenant as a parameter). Takes the decision_id of an allow or require_rx decision from gate_transaction.

• gate_transactionFree

  The gate: allow, deny or require_rx for a substance (name, INN or unii:), a pathway (licensed_medicine · lawful_compounding · cosmetic · food_or_supplement · ruo_not_cleared), an actor class, a channel and a ship-to. Returns a frozen reason code, the rule-set version, the source page and a decision_id for the downstream tools.

• get_availabilityFree

  Availability of a presentation once gate_transaction has answered allow or require_rx (decision_id): the availability block — banners[] on the shelf of record with licence footnote, pos_count (chain points of sale from the CPG Knowledge Graph retailer registry, or licensed dispensers on the provider directory for medicines), product_urls[] (retailer product page, register page, holder page) — plus tenant offers.

• get_compounding_eligibilityFree

  Whether a substance may be lawfully compounded in a jurisdiction and under which list or standard (503A/503B, provincial, magistral, Specials), from the register.

• get_enforcement_watchFree

  Dated, URL'd enforcement events for a substance or jurisdiction: warning letters, import alerts, shortage-list changes, committee votes, proposed and final rules, seizures, state notices.

• get_itemFree

  One authorised presentation by id (US package NDC, CA DIN, EU EMA number, KR MFDS item seq, CH Swissmedic authorisation/pack code, JP approved-list entry, or the catalogue id): brand, strength, form, route, device, pack, holder, status, offers (tenant is a parameter).

• get_label_and_indicationFree

  Label and indication pointers for a licensed presentation only (US package NDC, CA DIN, EU EMA number).

• get_lot_coaFree

  Certificate of analysis for a lawful lot of a presentation, where the pathway permits (decision_id required).

• get_pathway_statusFree

  The status of a substance on one pathway in one jurisdiction (frozen vocabulary), with effective date, rule-set version and source page.

• get_priceFree

  Price basis (list · contract · reimbursement) from a licensed party, once gate_transaction has answered allow or require_rx (decision_id).

• get_safety_labelFree

  Safety label pointers for licensed products (label page and the pharmacovigilance scheme of the jurisdiction).

• get_substance_recordFree

  One molecule: identifiers (INN, UNII, CAS, sequence hash), sourced aliases, class, one pathway row per jurisdiction × pathway, enforcement events, safety references. Every field carries its source page.

• log_auditwrite actionFree

  Write the audit line for a gate decision or an order intent (returns the line id).

• resolve_actorFree

  Resolve the actor class and channel. Classes: authorized_trading_partner and its members (manufacturer · repackager · wholesale_distributor · dispenser · third_party_logistics_provider; cosmetic_responsible_person · nhp_licence_holder on the non-drug pathways), prescriber, the referral classes patient and public, and agent (inherits the class of the credential it presents; none returns DENY_UNLICENSED_AGENT). Returns communication_class: trade_information or public.

• resolve_jurisdictionFree

  Resolve a ship-to (e.g. 'US-CA', 'CA-ON', 'MX', 'EU-DE', 'UK', 'KR', 'JP', 'SG', 'CH') to the gate's jurisdiction (US · CA · MX · EU · UK · KR · JP · SG · CH; UK is the jurisdiction name; the ISO 3166-1 code is accepted as input, machine fields carry the ISO code and jurisdiction_label carries UK), the EU member and any state, provincial or cantonal overlay.

• search_cleared_itemsFree

  Presentations that passed the gate for a jurisdiction, pathway and actor class (a query by substance, brand or holder; optional banner filter on the shelf of record). Only cleared statuses are returned; every item carries its availability block (banners, pos_count, product_urls).

• verify_serializationFree

  Verify a serialised pack (GTIN + serial + lot + expiry) against the serialisation regime of the jurisdiction (DSCSA · FMD · UK · KR; none-national elsewhere).
