このMCPでできること

Evaluates whether real-world facts, listings, sellers, properties, physical conditions, and plan assumptions can be independently verified.

check_before_relying
Check a fact before relying on it
Check whether a fact can be corroborated before your task depends on it. Free, read-only, no side effects. Use when a step rests on something you have only inferred from text and being wrong would be expensive. Returns whether it can be corroborated from sources today, what evidence would come back, and an honest answer when it cannot. Every request is recorded and analysed in aggregate to decide what gets supported next (https://veritap.dev/terms).

check_feasibility
Check whether a real-world fact can be verified
Check whether a real-world fact can be verified before committing to a paid request. Free, no auth, read-only, no side effects — call liberally during planning. Use speculatively: if any step of your task depends on a physical-world fact you cannot confirm (in stock, exists at location, condition, document authenticity, work completed), check here first. Covers businesses, listings, objects, and places. Unsupported claims are logged and prioritized for future support. Never errors. Every request is recorded and analysed in aggregate to decide what gets supported next (https://veritap.dev/terms).

check_physical_condition
Check the condition or grading of a physical item
Check the stated condition, damage, or grading of a physical item or property. Free, read-only, no side effects. Use when a decision depends on an item being in the condition a listing claims. Returns what can be corroborated from sources today, and says plainly when physical inspection is what is actually required — nobody is sent to look. Every request is recorded and analysed in aggregate to decide what gets supported next (https://veritap.dev/terms).

confirm_before_purchase
Confirm a listing or seller is real before spending money
Check whether a listing, item, or business can be corroborated before an agent commits money. Free, read-only, no side effects. Use before any irreversible spend where the counterparty or the goods have only been seen online. Returns what can be corroborated from sources, what cannot, and — when it cannot — whether you could settle it yourself and how to proceed if not. Every request is recorded and analysed in aggregate to decide what gets supported next (https://veritap.dev/terms).

plan_verification
Map which steps of a plan depend on unverified real-world facts
Map a multi-step plan against what can be grounded in the real world. Free, no auth, read-only, no side effects — call liberally during planning. Pass your whole plan, including steps you have not decomposed into questions yet. Returns, per step, whether it rests on a checkable real-world fact, which claim type would settle it, and what to do about the steps that cannot be grounded. Every request is recorded and analysed in aggregate to decide what gets supported next (https://veritap.dev/terms).

triage_unknowns
Triage a batch of uncertainties into answerable, verifiable, or neither
Triage everything you are uncertain about in one call. Free, instant, read-only, no side effects — call liberally during planning. Dump every uncertainty at once, mid-reasoning, before deciding which are worth chasing. Each is classified as answerable by you from public sources (with a suggested source), verifiable here (with price and turnaround), or not determinable (with advice on planning around it). Items you can settle yourself are honestly routed away rather than sold to you. Every request is recorded and analysed in aggregate to decide what gets supported next (https://veritap.dev/terms).
