Tools observed via MCP handshake

resolve_jurisdiction — Where is the media bought? Resolve a market (e.g. FR, UK, US, Japan) to one of the 20 markets on the record. UK is the label; GB is accepted.
resolve_actor — Who is asking? maker, brand_owner, agency, distributor or retailer_media_team (trade); auditor (read only). The consumer is never the counterparty.
gate_transaction — The gate before a handshake: allow or deny for one market and one actor class. Returns a decision_id the handshake tools ask for. A deny is not charged.
find_makers — Find the brand: makers on the grocery record of one market (node = one of the 20 markets). segment is taken as a lane where it names one (organic, free-from, pl
resolve_gtin — Confirm the product is real: is this Global Trade Item Number (GTIN) well-formed, and is it on the grocery record, with its brand and maker. Read live from the
check_eligibility — Confirm it is on the shelf: does the grocery record list this GTIN at this banner in this market? No listing, no media pitch. Read live from the A2A Grocery doo
list_banners — Pick the banners: the grocery banners of one market with each one's media program (or "none listed") and card status. with_program=true returns only banners wit
get_banner_card — The signed card of one banner and its status (unclaimed, claimed or registered). banner = the banner's slug, id or name.
list_banner_cards — The cards of one market, optionally by status (unclaimed, claimed, registered): banner, media program, status and the card's address.
list_packages — Match a package: what one banner's media program says it sells, in the program's own words, each tagged onsite, offsite or in-store. Offsite is tagged so it is
quote_package — Price it: returns where the banner's own media program publishes its rates or takes an enquiry. GSC never prices; a quote comes from the retailer's program.
find_buyer — Qualify the buyer: find a maker on the grocery record by name, with its own website where the record has one.
submit_demand — Hand off: the packet — the maker, a budget a person has approved, one or more GTINs, a market and a list of banners — or a gap naming what is missing. Routes ea
receive_demand — Retailer side: a registered program agent takes a qualified packet. Only a card in the registered state can receive; any other card is refused and nothing is ch
a2a_handoff — Hand to a person: the state of a handoff and its Navigator desk ticket, where the media program has no agent.
pull_measurement — Read the till: results of a campaign, returned by the retailer's program. Available only after the program returns a campaign id for a handoff.
renew_package — Renew: a prior quote id from the retailer's program and a new approved budget. Without a quote id from the program there is nothing to renew.
log_audit — Write one audit line for a step of the chain; returns its id.
enrol_maker — Makers: be seen. Enrol a maker for media exposure in grocery: its name, its markets (one or more of the 20), the tick, and a contact a person can answer. Enrolm
