Read-only tools for The Wild: spirits, altars, prices. Prayers, candles, witness stones are x402.
Scored across 5 tools
The five tools have mostly distinct purposes: spirits lists entities, altar inspects one altar, field gives today's overview, buy_kit returns a payment contract, and verify_witness performs a hash check. There is minor overlap between field and altar, and price information appears in both field and buy_kit, but the descriptions clarify the boundaries.
The names mix bare nouns (spirits, altar, field) with verb_noun forms (buy_kit, verify_witness). They are readable, but there is no predictable pattern an agent can rely on to infer whether a tool is read-only or action-oriented from its name alone.
Five tools is a well-scoped set for a focused surface covering discovery, daily state, single-altar detail, purchase-contract lookup, and witness verification. Each tool has a clear role and the set does not feel padded or thin.
The surface covers reading the domain and obtaining a purchase contract, but it lacks in-MCP state-changing operations such as actually praying, lighting a candle, or publishing witness words. buy_kit intentionally delegates payment to an external x402 client, and verify_witness mentions a reveal route without providing a tool for it, leaving notable action gaps.
One spirit's altar: its keeper, whether today's prayer slot is open, its lit days, the candles on it and the witness stones set at its feet. Read-only.
Inputs: spirit (required).
The exact HTTP contract for one paid act, from the published manifest: route, price and atomic amount, body, headers, the seal recipe, the signer rule and the reconcile rule. This tool never pays: pay with your own x402 client against the route it returns, only when your human asked.
Inputs: act (required), spirit.
Today in The Wild: which altars still take a prayer today (one per spirit per UTC day), the votive candles on the wall, witness stones today, and every price. Read-only; never pays.
Inputs: no named parameters.
The 24 animal spirits with their ids, names, habitats, plates and page links. Use an id with altar or buy_kit. Read-only.
Inputs: no named parameters.
Check words and a salt against a witness stone: recomputes sha256(salt + NUL + normalizedText) and compares it with the stone's commitment, and rechecks the stone's chain link. A pure hash check: nothing is stored or revealed. To publish the words, POST the reveal route instead.
Inputs: id (required), salt (required), text (required).
