FeedOracle Trust Layer - 10-tool cross-server trust: signing, anchoring, verification.
Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (10)
⚪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.
Input Schema
{
"type": "object",
"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)"
}
},
"required": [
"claim"
],
"additionalProperties": false
}🟢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WITHDRAWN (2026-08-09).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.
Input Schema
{
"type": "object",
"properties": {
"symbol": {
"type": "string",
"description": "Token symbol: USDC, RLUSD, EURC, USDT, DAI",
"enum": [
"USDC",
"RLUSD",
"EURC",
"USDT",
"DAI"
]
},
"fact_type": {
"type": "string",
"description": "Type: price, peg, market_cap, reserve",
"default": "price"
}
},
"required": [
"symbol"
],
"additionalProperties": false
}⚪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.
Input Schema
{
"type": "object",
"properties": {
"symbol": {
"type": "string",
"description": "Token symbol to trace"
}
},
"required": [
"symbol"
],
"additionalProperties": false
}🟢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 Prevents agent decisions based on outdated information.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.
Input Schema
{
"type": "object",
"properties": {
"symbol": {
"type": "string",
"description": "Token symbol (optional — checks overall feed if omitted)"
},
"max_age_seconds": {
"type": "integer",
"description": "Maximum acceptable age in seconds (default: 300)",
"default": 300
}
},
"additionalProperties": false
}🟢hallucination_check(statement, context)
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 Schema
{
"type": "object",
"properties": {
"statement": {
"type": "string",
"description": "The statement to check against evidence"
},
"context": {

}
},
"required": [
"statement"
],
"additionalProperties": false
}⚪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.

"properties": {
"jws": {
"type": "string",
"description": "JWS token to verify"
},
"content_hash": {
"type": "string",
"description": "Content hash to verify (sha256:...)"
}
},
"additionalProperties": false
}⚪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.

"default": "cite"
},
"min_confidence": {
"type": "integer",

"minimum": 0,
"maximum": 100
}
},
"required": [
"symbol"
],
"additionalProperties": false
}🟡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.

"properties": {
"fact": {
"type": "string",
"description": "The fact to anchor"
},
"symbol": {
"type": "string",
