## 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 2026-08-03.

- **Endpoint Security**: 66/100
  - 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 10 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.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 761 tokens (~76/item across 10 items; 10 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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.
- **Capabilities**: 40/100
  - Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 68, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-01 (score 67, +1)

No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-07-31 (score 66, +1)

First indexed and scored.

## MCP tools (10)

### `verify_claim` (~101 tokens)

Verify an agent's claim against FeedOracle signed evidence. Checks if a statement (e.g. 'USDC market cap is $32B') matches live, cryptographically signed data. Returns verified/partially_verified/unverified with confidence score and recommended action.

Input parameters:

- `claim` (string, required): The claim to verify, e.g. 'USDC has $32B market cap'
- `symbol` (string): Token symbol (auto-detected from claim if omitted)

### `get_signed_fact` (~83 tokens)

Get a cryptographically signed, machine-verifiable fact. Returns ES256K-signed data with JWKS verification URL. Other agents can independently verify the signature.

Input parameters:

- `fact_type` (string): Type: price, peg, market_cap, reserve
- `symbol` (string, required): Token symbol: USDC, RLUSD, EURC, USDT, DAI

### `provenance_trace` (~66 tokens)

Full data provenance chain — traces every data point from external source (CoinGecko, ESMA, on-chain) through FeedOracle processing to final delivery. Each step individually hashed. Supports EU AI Act Art. 13 transparency requirements.

Input parameters:

- `symbol` (string, required): Token symbol to trace

### `freshness_guard` (~70 tokens)

Check if data is current, stale, or expired. Prevents agent decisions based on outdated information. Configurable max age threshold.

Input parameters:

- `max_age_seconds` (integer): Maximum acceptable age in seconds (default: 300)
- `symbol` (string): Token symbol (optional — checks overall feed if omitted)

### `hallucination_check` (~68 tokens)

Compare an agent's statement against ground truth evidence. Detects factual mismatches and dangerous hallucination patterns (absolute language, suspect claims). Returns evidence checks and red flags.

Input parameters:

- `context` (string): Optional context for the statement
- `statement` (string, required): The statement to check against evidence

### `verify_signature` (~71 tokens)

Verify a JWS or DSSE signature from FeedOracle evidence. Confirms cryptographic integrity and origin authenticity. Public JWKS at /.well-known/jwks.json.

Input parameters:

- `content_hash` (string): Content hash to verify (sha256:...)
- `jws` (string): JWS token to verify

### `confidence_gate` (~103 tokens)

Decision gate for agents: should I proceed, exercise caution, abstain, or escalate? Evaluates multi-factor confidence for a specific action type (cite, trade, report, recommend) against a threshold.

Input parameters:

- `action_type` (string): What the agent wants to do: cite, trade, report, recommend
- `min_confidence` (integer): Minimum confidence to proceed (0-100, default: 70)
- `symbol` (string, required): Token to evaluate

### `evidence_anchor` (~82 tokens)

Anchor a fact on-chain (Polygon) as immutable, timestamped evidence. Creates an append-only registry entry with pack_id and content hash. Tamper-proof audit trail.

Input parameters:

- `framework` (string): Framework context: trust_layer, mica, dora
- `symbol` (string): Related token symbol (optional)

### `agent_reputation` (~84 tokens)

Get trust score and reputation for an AI agent from FeedOracle KYA (Know Your Agent) system. Returns trust level (UNVERIFIED → CERTIFIED), score (0-100), and registration details.

Input parameters:

- `agent_name` (string): Agent name to search (if client_id unknown)
- `client_id` (string): Agent's client_id from KYA registration

### `trust_status` (~33 tokens)

Trust Layer infrastructure health, capabilities, and component status. Shows which verification services are online and what the Trust Layer can do.
