Diavgis — Greek Public Procurement MCP Server

Top counterparties of an entity (ΑΦΜ): for a buyer, the suppliers it pays most; for a supplier, its top public buyers — with act counts and EUR totals. The 'who does business with whom' due-diligence view.

Resolve a Greek buyer or supplier NAME to its ΑΦΜ. For when you have a name but no ΑΦΜ: get_entity, entity_counterparties and the buyer_afm/supplier_afm filters take the 9-digit number. Matching is accent- and case-insensitive; returns the closest names with their ΑΦΜ.

Profile of a legal entity (company or public body) by 9-digit ΑΦΜ: name, role, and spend/receipt statistics as buyer and as supplier. EUR totals = the COMMITTED procurement value counted ONCE per procurement (deduplicated across ΚΗΜΔΗΣ/Διαύγεια sources and the award→contract→payment lifecycle; tenders/budgets excluded), so it reflects real committed spend, not a sum of every published act.

Full detail of one act by its id (Διαύγεια ΑΔΑ, ΚΗΜΔΗΣ 'kimdis:<ΑΔΑΜ>', or TED 'ted:<number>'): canonical fields, resolved buyer/supplier entities, CPV codes with labels, and its cross-source lifecycle chain if linked. On ΚΗΜΔΗΣ contracts, `commitment_ada` carries the Διαύγεια ΑΔΑ of the budget-commitment decision the source declares (comma-separated when more than one). It is a pointer INTO Διαύγεια, not an act we necessarily hold — resolve it at diavgeia.gov.gr, not through this API — and it is deliberately NOT a chain edge: one annual commitment funds many unrelated contracts. On tenders and public-works awards/contracts, `discount` carries the contractor discount (official from the document, or calculated) — see its schema.

A reconstructed procurement lifecycle chain by chain_id: the linked sequence of related acts (e.g. commitment → award → contract → payments) with confidence and link method. Get a chain_id from the chain_id field of any act. A chain is ONE procurement's lifecycle, not everything an act references: an administrative umbrella cited by more than 25 acts (e.g. one annual expense-approval decision referenced by thousands of a buyer's acts) is deliberately NOT merged, so a chain never swallows a year of unrelated activity. Those references are still published — see the act's own references — they simply do not form a chain.

Greek public contracts that are RUNNING NOW and expire within a horizon of 0, 7, 30 or 180 days — the renewal pipeline. Each row carries who currently holds the contract and HOW it was awarded (direct award vs competitive tender, and the number of bids where the source reports it), which is what tells you whether the re-tender is worth chasing. One procurement is counted ONCE: Greek sources publish the duration on the award record as well as the contract, so award records are dropped when a contract in the same lifecycle chain already defines the expiry. ⚠ `expiry_basis` on every row states how the date was obtained — `published` (the buyer published an end date), `computed_from_start` (start date + declared duration) or `computed_from_publication` (no start date published, so the publication date was substituted; systematically early). A computed date is an estimate, not a published date. ACCESS: horizon 0 (expiring today) is free on every plan and returns the complete record. Horizons 7/30/180 require a paid plan — lead time is the paid product.

What your Diavgis plan allows right now (the same for an API key and a connected account): plan, calls used this period, calls remaining, per-minute rate, page-size and pagination caps, and when the period resets. Free — this call is not counted against the quota. Useful for sizing a long job.

Rank top Greek public-procurement entities. role=buyer (default) or supplier; by=spend (default — COMMITTED procurement value in EUR, counted ONCE per procurement: deduplicated across sources and lifecycle stages, tenders excluded), single_bidder (count of ≤1-bid awards/contracts) or direct_award (count of απευθείας ανάθεση). Answers 'top 10 suppliers by public revenue', 'which buyers award most without competition'. Returns afm, name, metric, total. Precomputed and refreshed every 6 hours, so it is instant and always the top 15.

Committed public procurement value by CPV category (2-digit division), optionally for one year. Value = counted ONCE per procurement (deduplicated across sources and award/contract/payment stages; tenders excluded). Answers 'what does the Greek state spend the most on'. Returns cpv_division, acts, spend (EUR) for the top divisions by spend — precomputed nightly, so it is instant. Divisions outside the top list are available through search_tenders with cpv=.

Search Greek public-procurement acts across THREE cross-linked sources — Διαύγεια, ΚΗΜΔΗΣ (Central Electronic Public Procurement Registry) and EU TED. Filter by source (diavgeia|kimdis|ted), lifecycle status (request|tender|award|contract|payment), buyer or supplier ΑΦΜ (9-digit tax id), CPV code, EUR budget range, NUTS region, submission deadline (deadline_after=TODAY + status=tender ⇒ the OPEN tenders a supplier can still bid on), free-text q over the act title, and procurement signals (published facts from ΚΗΜΔΗΣ): direct_award (απευθείας ανάθεση), single_bidder (≤1 bid on the contract), cancelled. Returns a paginated envelope; 'next' is the next PAGE NUMBER or null. Natural-person counterparties are redacted. Summing amount_net across results double-counts, because one procurement appears at several stages; rank_entities and spend_by_cpv count each procurement once.
