Tools & Capabilities Breakdown

QnEvt Verifiable Randomness MCP Tools (0)

No explicit tool names declared in metadata yet. Check project README on main listing page.

Horizon Shield Tools (14)

get_price_range

Returns the fair price range (min, avg, max), the overcharge danger threshold, unit, price trend, and field notes for a Japanese construction or renovation job.

audit_estimate

Given a work name and a quoted price in JPY, judges it as fair, a bit high, or overcharge risk, and returns the gap from the average.

verify_fair_price

Returns a fair price as a tamper evident record with a SHA-256 hash, under the PTKA (Pre-Transaction Knowledge Anchoring) model: a third party records the fair price before the contractor quote.

check_red_flags

Checks whether wording in an estimate or sales pitch matches known overcharge or high pressure tactics (lump sum, today only discount, free inspection, door to door). Language agnostic.
