このMCPでできること

Provides agent trust and evidence checks, including reputation, freshness, hallucination detection, claim verification, confidence gating, and provenance tracing.

agent_reputation
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.
入力スキーマ
{'type': 'object', 'properties': {'client_id': {'type': 'string', 'description': "Agent's client_id from KYA registration"}, 'agent_name': {'type': 'string', 'description': 'Agent name to search (if client_id unknown)'}}, 'additionalProperties': False}
confidence_gate
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.
入力スキーマ
{'type': 'object', 'required': ['symbol'], 'properties': {'symbol': {'type': 'string', 'description': 'Token to evaluate'}, 'action_type': {'type': 'string', 'default': 'cite', 'description': 'What the agent wants to do: cite, trade, report, recommend'}, 'min_confidence': {'type': 'integer', 'default': 70, 'maximum': 100, 'minimum': 0, 'description': 'Minimum confidence to proceed (0-100, default: 70)'}}, 'additionalProperties': False}
evidence_anchor
WITHDRAWN (2026-08-09). This tool does not submit any blockchain transaction and creates no on-chain anchor or proof; it returns a non-success withdrawal notice.
入力スキーマ
{'type': 'object', 'required': ['fact'], 'properties': {'fact': {'type': 'string', 'description': 'The fact to anchor'}, 'symbol': {'type': 'string', 'description': 'Related token symbol (optional)'}, 'framework': {'type': 'string', 'default': 'trust_layer', 'description': 'Framework context: trust_layer, mica, dora'}}, 'additionalProperties': False}
freshness_guard
Check if data is current, stale, or expired. Prevents agent decisions based on outdated information. Configurable max age threshold.
入力スキーマ
{'type': 'object', 'properties': {'symbol': {'type': 'string', 'description': 'Token symbol (optional — checks overall feed if omitted)'}, 'max_age_seconds': {'type': 'integer', 'default': 300, 'description': 'Maximum acceptable age in seconds (default: 300)'}}, 'additionalProperties': False}
get_signed_fact
WITHDRAWN (2026-08-09). This tool does not produce or verify a cryptographic signature and returns a non-success withdrawal notice. Do not rely on it for signed evidence.
入力スキーマ
{'type': 'object', 'required': ['symbol'], 'properties': {'symbol': {'enum': ['USDC', 'RLUSD', 'EURC', 'USDT', 'DAI'], 'type': 'string', 'description': 'Token symbol: USDC, RLUSD, EURC, USDT, DAI'}, 'fact_type': {'type': 'string', 'default': 'price', 'description': 'Type: price, peg, market_cap, reserve'}}, 'additionalProperties': False}
hallucination_check
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.
入力スキーマ
{'type': 'object', 'required': ['statement'], 'properties': {'context': {'type': 'string', 'description': 'Optional context for the statement'}, 'statement': {'type': 'string', 'description': 'The statement to check against evidence'}}, 'additionalProperties': False}
provenance_trace
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.
入力スキーマ
{'type': 'object', 'required': ['symbol'], 'properties': {'symbol': {'type': 'string', 'description': 'Token symbol to trace'}}, 'additionalProperties': False}
trust_status
Trust Layer infrastructure health, capabilities, and component status. Shows which verification services are online and what the Trust Layer can do.
入力スキーマ
{'type': 'object', 'properties': {}, 'additionalProperties': False}
verify_claim
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.
入力スキーマ
{'type': 'object', 'required': ['claim'], 'properties': {'claim': {'type': 'string', 'description': "The claim to verify, e.g. 'USDC has $32B market cap'"}, 'symbol': {'type': 'string', 'description': 'Token symbol (auto-detected from claim if omitted)'}}, 'additionalProperties': False}
verify_signature
WITHDRAWN (2026-08-09). This tool performs no cryptographic signature verification and returns a non-success withdrawal notice. A hash comparison is not signature verification.
入力スキーマ
{'type': 'object', 'properties': {'jws': {'type': 'string', 'description': 'JWS token to verify'}, 'content_hash': {'type': 'string', 'description': 'Content hash to verify (sha256:...)'}}, 'additionalProperties': False}
