What this server can do

10 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

agent_reputation(client_id, agent_name)
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.
confidence_gate(symbol, action_type, min_confidence)
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. Required: symbol.
evidence_anchor(fact, symbol, framework)
WITHDRAWN (2026-08-09).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. Required: fact.
freshness_guard(symbol, max_age_seconds)
Check if data is current, stale, or expired. Prevents agent decisions based on outdated information. Configurable max age threshold.
get_signed_fact(symbol, fact_type)
WITHDRAWN (2026-08-09).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. Required: symbol.
hallucination_check(context, statement)
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. Required: statement.
provenance_trace(symbol)
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. Required: symbol.
trust_status
Trust Layer infrastructure health, capabilities, and component status. Shows which verification services are online and what the Trust Layer can do.
verify_claim(claim, symbol)
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. Required: claim.
verify_signature(jws, content_hash)
WITHDRAWN (2026-08-09).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.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
