TDQS

A4.5/5.0

Scored across 5 tools

Disambiguation5/5

Each tool maps to a distinct workflow stage: coverage discovery, x402 challenge retrieval, payment-channel status, single-record verification, and triangular cross-verification. The two payment-adjacent tools are clearly separated by one returning the challenge URL and the other reporting available channels and statuses.

Naming Consistency5/5

All tool names follow a consistent snake_case verb_noun pattern: find_signal, get_official_record, purchase_options, verify_citation, verify_triangular. The two verify_* tools are parallel, and the verb-first naming makes the overall set predictable and easy to scan.

Tool Count5/5

Five tools is a well-scoped size for a niche payment-discovery and verification server. Each tool covers a necessary non-payment step in the workflow, and none feels redundant or like filler.

Completeness5/5

The set covers the full intended lifecycle: find coverage, obtain the payment challenge, learn payment channels, verify a delivered record, and verify an interweave line. Since paid data delivery is deliberately external to MCP and records are immutable attestations, the lack of create/update/delete or direct data-fetch tools is not a gap.

Available Tools

5 tools
find_signalFind which signals/entities are covered (free)A
Read-onlyIdempotent
Inspect

FREE coverage + freshness manifest: which signal_id lines exist, how many entities each covers, and fresh/recent/stale counts - so you can check "is my entity covered and how fresh" BEFORE paying. Optional filters: industry, signal_id, entity.

Inputs: full, entity, industry, signal_id. Returns: Coverage + freshness manifest. On failure this object is an error report instea…

get_official_recordGet the x402 payment challenge for a paid recordA
Read-onlyIdempotent
Inspect

Returns the REAL x402 payment challenge (accepts[]: network / asset / payTo / amount) for the paid endpoint that serves a given signal_id+entity, or any listed endpoint addressed directly by path. This tool does NOT deliver paid data and does NOT take payment - MCP has no payment layer. Pay at the returned url with your own x402 client (USDC on Base or Solana, gasless EIP-3009; pay from a plain EOA) and you receive the record directly, with record_hash you can verify offline. This tool only fetches the 402 challenge; it delivers no paid data and collects no payment.

Inputs: dim, path, entity, signal_id. Returns: The real x402 payment challenge and how to pay it. No paid data is ever returne…

purchase_optionsHow can I actually buy this? (free)A
Read-onlyIdempotent
Inspect

FREE. Ask how to pay for a listed endpoint and get every channel with its REAL status - including the ones that are wired but not open yet. Three channels exist: x402 micropayment (for an agent with a funded USDC wallet on Base), a stateless subscription Bearer token (for a person or team - no wallet, no private key, no account), and a card rail. This tool takes no payment and holds no key; it only tells you which doors exist and which are open today.

Inputs: path. Returns: error, price, title, detail, +5 more

verify_citationVerify a Truth Bear record (free)A
Read-onlyIdempotent
Inspect

FREE. Given a record_hash from any Truth Bear record, look it up and recompute the canonical hash server-side, returning whether it is a genuine Truth Bear official record plus a plain-language reverse lookup of what exactly that hash attests. Use this to check a citation you were handed by another agent or document BEFORE relying on it. No payment, no API key.

Inputs: record_hash (required). Returns: Verdict for one record_hash. On failure this object is an error report instead…

verify_triangularCross-check a line of official series & recompute the verdict (free)A
Read-onlyIdempotent
Inspect

FREE. Cross-verify one GAUGE interweave line: it returns each official series ("leg") in the line with its own record_hash, current/previous values, expected direction and per-leg minMove deadband, plus a count-style state (directions_matched / direction_mismatch / inverse_consistent / not_comparable / insufficient) and N-of-M. Everything needed to recompute the verdict OFFLINE is in the response - verify each leg hash with verify_citation, then recompute dir=sign(current-previous) with the minMove deadband. Descriptive only: no forecast, no causation, no advice. No payment, no API key.

Inputs: line (required), entity (required). Returns: Count-style read of one interweave line: how many official series moved in thei…
