• Todas as ferramentas passam nas seis verificações.

Um programa verifica o servidor uma vez por dia: initialize e tools/list, sem modelo. Os tokens são o tamanho das definições, a cerca de quatro caracteres por token. A nota é a média de seis verificações do nome, da descrição, do esquema e das anotações de cada ferramenta; diz se as ferramentas estão bem descritas, não se funcionam. A nota pesa só o que foi medido: se responde (25%), se faz o trabalho do produto (25%), definições (20%), contexto (10%), uso (10%) e a facilidade de conectar (10%). Uma parte não medida fica de fora, e uma instrução oculta limita a nota a 40. O estado dos servidores MCP dos fornecedores: método e números →

• read_store_guide

  The store's front door as text: the full menu with prices, how x402 payment works here, the free shelf, and the house promises. Free. Completes when the guide text returns. NOT a purchase or payment endpoint — to buy, call a buy_* tool…

  Ring the store bell. Free, once a day per visitor; the count is public; a fresh ring presses one signed common card. Completes when the result carries the bell's message and count. A store errand, for you the visiting agent — nothing here…

  Read a wallet's binder: every trading card it holds here, newest first, with page, face, sheet and record URLs, and the pack credit. Free, no account. A listing, not a proof; the signed records are. Completes when the result carries cards…

• look_in_window

  Look in the shop window: the last five pressings pulled from packs here, each with its page. Free, no account. A window pick (buy_window_pick, half a pack) takes one; the seed chooses and the card moves to the picker's binder. Completes…

• look_at_door

  What this store holds about an x402 door, now and before now, in one free call. One unpaid probe (the same single probe as preflight_endpoint, same budget) folded with what the signed chain holds about the host: rounds probed out of…

• check_before_you_pay

  For a buyer whose client has its own rules, to learn before signing whether this door meets them. Before paying any x402 door, find out what YOUR client will actually do with it, free: one unpaid probe, then the stock @x402/core selection…

  x402 receipt verification and signed-offer verification, free, against the issuer's published key. For anyone holding a signed x402 offer or receipt and unsure whether it is good, whoever issued it. Check any issuer's x402 signed offer or…

• verify_artifact

  Verify anything scvd.store has ever signed — certificates, visit stamps, context anchors — by its id. Free, unlimited. Completes when the result carries valid (true/false) and the artifact record. NOT a conformance checker for other x402…

• check_order

  Check a human-queue order by its order_id: status (queued or completed), the promised window, and once completed the deliverable itself — the poll half of the store's async-job pattern, the same record GET /api/order/{order_id} serves…

• find_in_catalog

  Find an item before using buy_*: filter the shelf by price or text, or pass item_id for its listing. Rows give USDC price, fulfillment and read scope. Free, read-only, no account. Results stay in shelf order; nothing is ranked or…

• buy_simple

  Purpose: buy one of the few things that need no reading at all — the front counter. Every one of these takes no arguments, costs one fixed price, arrives in the response, and cannot sell out. Buy it in one call and you are done — nothing…

• buy_signed_record

  Purpose: buy a signed certificate — a signed, dated record that permanently records something — a greeting, a claim, a mark, a grievance, a confession, a contribution, or a standing pass. Every one returns an ed25519-signed artifact with…

• buy_human_task

  Purpose: hire the keeper — a real named human — to do something in the physical or judgment world that an agent cannot do for itself. Two doors: the_collab is whatever keeper-time can be — a call placed, a thing witnessed, a verdict given…

• buy_observation

  Purpose: independent signed x402 research comparisons, settlement attestations, x402 conformance audits, x402 endpoint monitoring, x402 payment client tests, x402 launch checks and Bitcoin timestamps. To record prior spending authority…

• buy_mandate

  Purpose: record what an agent is authorized to do BEFORE it spends — the claimed instructions verbatim, who submitted them (agent or principal, itself a claim), an optional declared cap in USDC and expiry — as a signed, dated record held…

• buy_memory_anchor

  Purpose: sign and store a summary of your own state — who you are, what you were doing — at a permanent URL you can read back after a context reset, a restart, or a handoff to another agent. The store holds it; the signature proves it was…

• buy_small_pleasure

  Purpose: buy a small signed novelty — a blessing from the jar, the day's fortune (the same line for every buyer until midnight UTC), a lucky totem from the keeper's collection, a pack of five trading cards, or one off the window…
