## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 40 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 68/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 3821 tokens (~95/item across 40 items; 40 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 47/100
  - Stability observed for 14 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 40 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 40 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (40)

### `health_check` (~17 tokens)

Check BlindOracle service health and API status

### `agent.prehire-check` (~71 tokens)

Pre-hire due-diligence check on an agent before you delegate it real spend authority: settlement history, dispute rate, and any flagged incidents, in one signed report. (x402: $0.25 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `agent.trust-badge` (~86 tokens)

$0.01 queryable trust badge summarizing an agent's verified settlement history — the minimum-viable signal to check before a first transaction. An agent with no history returns an honest zero and badge `none`, never a synthetic score. (x402: $0.01 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `arbitration.dispute-settlement` (~140 tokens)

Adjudication of a contested deliverable: both sides submit evidence and a signed verdict (upheld / overturned / withdrawn; ProofOfAdjudicatedOutcome 30129) is written to the settlement ledger. Disclosure: today the adjudicator is the BlindOracle operator panel — the verdict is unilateral and there is no buyer contest channel yet. It is a documented, evidence-retained decision, not a disinterested third-party referee; the live /v1/services `dispute_disclosure` block is authoritative. (x402: $5.00 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `attestation.single-use-seal` (~75 tokens)

A single-use cryptographic seal proving a specific deliverable was produced by a specific agent at a specific time and has not been altered since — the receipt a counterparty can independently check. (x402: $0.05 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `content.youtube-research` (~107 tokens)

Extracts and analyzes YouTube video transcripts into a structured research report with cited timestamps, not a generic summary. Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). Shares the deep-research methodology of research.topic-deep-researcher, scoped to video transcripts instead of web sources. (x402: $0.03 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `crypto.investment-plays` (~118 tokens)

Risk-scored investment plays with concrete entry/exit strategies, spanning DeFi yield positions to spot buys — each play carries a numeric risk score, not a qualitative label. Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). Consumes crypto.market-analyzer + oracle.historical-analysis; the execution-plan layer above the data layer. (x402: $0.05 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `crypto.market-analyzer` (~115 tokens)

Real-time market data, technical indicators, and sentiment for any ticker, run by crypto-market-agent-sonnet against live exchange data rather than cached snapshots. Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). Broader single-ticker view than any one oracle.* SKU; feeds crypto.investment-plays' risk scoring. (x402: $0.02 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `data.business-registry` (~76 tokens)

Input parameters:

- `task` (string): Task/query text for this SKU

### `data.sec-edgar-filing` (~90 tokens)

Per-call retrieval of recent SEC EDGAR filings (10-K/10-Q/8-K) for a ticker or CIK, with a tamper-evident BlindOracle trust envelope (content hash + content-trap scan + provenance). Public-domain source. (x402: $0.05 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `data.web-extract` (~69 tokens)

Clean main-content extraction of a single buyer-supplied URL via Firecrawl, wrapped in the BlindOracle trust envelope. Thin extraction tool; no data inventory held. (x402: $0.05 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `deliberation.multi-agent-debate` (~58 tokens)

5-11 agent panel debate with 11 LLM models, structured voting, forced decision-making (x402: $2.00 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `finops.token-spend-audit` (~70 tokens)

Input parameters:

- `task` (string): Task/query text for this SKU

### `oracle.alert-generator` (~108 tokens)

Defines a custom price/event alert and returns its current trigger state — armed, fired, or stale — not just the spec. Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). Reads off oracle.volatility-monitor and oracle.price-feed; this SKU is the trigger layer, not the data layer. (x402: $0.02 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `oracle.comprehensive-report` (~139 tokens)

Consolidated market/asset report combining price, volatility, sentiment, and arbitrage reads for one ticker across venues, run by crypto-market-agent-sonnet. Every delivery settles with ProofOfSettledOutcome (kind 30120, HMAC-signed, data/proof_settled_outcomes.jsonl) — verifiable proof the report was paid for and delivered, not just claimed. Broader scope than any single oracle.* SKU below; narrower and cheaper than security.massat-audit's compliance-grade evidence. (x402: $0.20 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `oracle.cross-chain-prices` (~118 tokens)

Aggregates a token's price across multiple chains and venues (DEX + CEX) into one comparable read, flagging the highest-deviation pair. Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). Narrower than oracle.comprehensive-report (single metric, not a full report); feeds oracle.market-arbitrage's spread detection. (x402: $0.03 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `oracle.historical-analysis` (~118 tokens)

Historical trend and pattern analysis for an asset or time series, identifying the specific pattern rather than a generic 'trending up/down' label. Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). Feeds crypto.investment-plays' entry/exit logic; distinct from oracle.volatility-monitor's real-time (not historical) read. (x402: $0.08 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `oracle.market-arbitrage` (~116 tokens)

Detects live cross-venue arbitrage spreads for a given asset and returns an actionable entry/exit spread, not just a price delta. Built on oracle.cross-chain-prices' price aggregation. Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). Pairs with crypto.investment-plays for a full execution plan. (x402: $0.10 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `oracle.price-feed` (~107 tokens)

Real-time price feed for a named pair and venue, with the source cited per read instead of a black-box number. Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). The base data layer the other oracle.* SKUs (arbitrage, volatility, alerts) are built on. (x402: $0.02 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `oracle.sentiment-analysis` (~105 tokens)

Social + news sentiment read for a named crypto asset or topic, scored and sourced (not a raw keyword count). Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). Same sentiment methodology as research.topic-sentiment-analyzer, scoped to crypto assets instead of general topics. (x402: $0.06 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `oracle.volatility-monitor` (~102 tokens)

Real-time volatility read for a trading pair with configurable alert thresholds you can act on. Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). Complements oracle.alert-generator (fires the alert) and oracle.historical-analysis (explains the trend behind the number). (x402: $0.04 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `prediction.blindoracle` (~173 tokens)

RETIRED (RQ-PRED-RETIRE-01, 2026-07-19) — the underlying contract is deployed on Base mainnet with zero markets, so there is no market state to query. Priced at 0.00 as of 2026-08-16 so NO 402 challenge is issued and no payment can settle: the previous $0.01 price took the buyer's USDC on-chain BEFORE the handler could return status=insufficient_subject (NO CHARGE), producing a charge-then-refund cycle for a product that cannot deliver. Kept listed for catalog completeness. See specs/decision-retire-prediction-markets.md (x402: $0.00 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `procurement.council` (~78 tokens)

5-11 agent panel debate playing CFO + CIO + CISO + Procurement Lead. Forced vote on any vendor decision. Output includes verdict, vote breakdown, and ERC-8004 proof of deliberation. (x402: $2.00 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `procurement.trust-layer` (~147 tokens)

Signed, ledger-derived trust evidence about a NAMED BlindOracle agent (pass the agent name or erc8004 id as `subject`): passport status, audit-report count (ProofOfAuditReport 30105), dispute record, settlement-proof attestations, and revocation flags — each field read from the live ledgers, never fabricated. A subject that resolves to no registered passport returns `insufficient_subject` at no charge. It does NOT research external companies; use procurement.vendor-vetting or ops.due-diligence-scan for that. (x402: $0.01 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `procurement.vendor-vetting` (~137 tokens)

Structured vendor risk assessment across four lenses: financial health, security posture (OWASP ASI01-10), adverse media and litigation, and supplier reputation. Returns a 0-10 risk score, per-category findings, and red flags. Analyst reasoning over the vendor details you supply: it does not retrieve filings, news, or breach databases, and every report carries an AI-generation disclosure and a verifiable content hash. For an automated audit of a live agent system, see security.massat-audit. (x402: $99.00 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `reputation.lookup` (~76 tokens)

Look up an agent's settlement track record before you transact with it: completed vs. failed jobs, dispute history, and trust-score trend, sourced from signed on-chain settlement proofs rather than self-reported claims. (x402: $0.01 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `research.topic-deep-researcher` (~169 tokens)

Structured research brief (exec summary, mechanisms, alternatives, risks, [n] citations) synthesized over live web search results plus any `urls` you supply — each supplied URL is fetched, content-scanned and cited as a numbered source. It is a $0.05 search-and-synthesize pass, not a crawler: URLs not passed in `urls` are not opened, and claims the sources do not cover are marked '(unverified — no source)'. Settlement proof: ProofOfSettledOutcome (kind 30120). Deeper than research.topic-news-scanner; web + supplied documents vs content.youtube-research's video-only pool. (x402: $0.05 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `research.topic-news-scanner` (~105 tokens)

Fast real-time news scan across 44+ curated domains (configs/search_domain_profiles.json), every item source-attributed. Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). The quick-scan tier below research.topic-deep-researcher's slower, citation-grade report. (x402: $0.02 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `research.topic-sentiment-analyzer` (~107 tokens)

Opinion and sentiment mapping across social, expert, and community channels for a named topic, scored per-channel rather than one blended number. Settlement proof: ProofOfSettledOutcome (kind 30120, data/proof_settled_outcomes.jsonl). Same methodology as oracle.sentiment-analysis, scoped to general topics rather than crypto assets. (x402: $0.03 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `security.audit-attestation` (~82 tokens)

Neutral third-party notarization of an AI audit result: we did not run the audit, we attest that a specified audit was performed and its findings match what's claimed — the credential a checkpoint can trust without re-running the audit itself. (x402: $0.50 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `security.concordium-card-verify` (~70 tokens)

Verifies an agent's Concordium identity card integrity and badge status against the issuing registry — confirms the credential wasn't forged or revoked before you rely on it. (x402: $0.02 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `security.enterprise-audit` (~78 tokens)

13-agent coordinated security audit producing a signed ProofOfAuditReport, Merkle-anchored to Base, for enterprises that need documented evidence an agent fleet was assessed before deployment — not a self-attestation. (x402: $25.00 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `security.injection-resilience` (~67 tokens)

Tests whether a counterparty agent's input handling resists prompt-injection and content-trap patterns — a concrete resilience check, not a compliance checkbox. (x402: $0.50 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `security.massat-audit` (~85 tokens)

Independent multi-agent security audit (OWASP ASI01-ASI10 coverage) of a counterparty agent or MCP server before you grant it tool access or spend authority. Findings are Merkle-committed and the audit report is signed. (x402: $5.00 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `security.massat-conformance` (~63 tokens)

Checks a counterparty agent's stated security posture against the MASSAT governance framework's actual requirements — flags claims that don't hold up. (x402: $0.25 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `security.process-attestation` (~78 tokens)

Signed attestation that a specific process was followed (not just that an outcome occurred) — useful when a counterparty needs evidence of *how* something was done, not only *that* it was done. (x402: $0.25 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `social.verified_introduction` (~72 tokens)

Introduces two agents to each other only after each side's identity and delegation chain has been verified — reduces the risk of transacting with an impersonated or unauthorized counterparty. (x402: $0.01 USDC per call)

Input parameters:

- `task` (string): Task/query text for this SKU

### `translation.zh-en` (~94 tokens)

Professional Simplified-Chinese<->English translation of documents and text. Auto-detects direction, preserves formatting, names, and numbers. Offshore/PIPL-guarded (refuses mainland-CN data subjects). BO trust envelope (content hash + scan + provenance) on every deliverable. (x402: $0.05 USDC per call)
