What this MCP does

Produces and verifies signed ground-truth verdicts, screens names against OFAC sanctions, calculates equity distress scores, and supports bonded verdict disputes.

Capabilities

Tools

5 tools
claim_verdict
Submits a claim and returns a signed verdict: settled against real external ground truth (GitHub PR, on-chain tx, HTTP status, JSON field, Kalshi market, or multi-exchange price consensus), Ed25519-signed, hash-chained. Free tier -- no account, no card. Returns CONFIRMED, REFUTED, or ERROR -- never a forced guess.
Input schema 
{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'required': ['agent', 'claim', 'resolver'], 'properties': {'agent': {'type': 'string', 'description': 'who is asking (shown on the public reputation ledger)'}, 'claim': {'type': 'string', 'description': 'the claim in plain language, e.g. "PR #42 on owner/repo is merged"'}, 'resolver': {'type': 'object', 'required': ['type'], 'properties': {'type': {'enum': ['github_pr', 'onchain_tx', 'url_json', 'http_status', 'kalshi_market'], 'type': 'string'}}, 'description': 'which external source resolves this claim', 'additionalProperties': {}}}}
distress_score
Validated corporate distress-foresight score for a single equity ticker: Altman Z-score computed from live SEC XBRL filings, backtested 71% sensitivity / 100% specificity with a ~109-day median lead time, Ed25519-signed. Paid: $0.15 USDC (Base) via x402 -- no free tier. A call without an attached x402 payment returns the payment requirement, not a verdict.
Input schema 
{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'required': ['agent', 'ticker'], 'properties': {'agent': {'type': 'string', 'description': 'who is asking (shown on the public reputation ledger)'}, 'ticker': {'type': 'string', 'description': 'equity ticker to score, e.g. "AAPL"'}}}
file_dispute
Files a bonded dispute against a verdict receipt: the disputed verdict is re-resolved immediately against the identical resolver specification that produced it -- independent re-run, not a re-vote. An upheld dispute overturns the verdict and queues a slashable payout against the notary's on-chain correctness bond. Paid: $1.00 USDC (Base) via x402 -- no free tier. A call without an attached x402 payment returns the payment requirement (price, payTo, asset), not a verdict.
Input schema 
{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'required': ['agent', 'receipt_hash'], 'properties': {'agent': {'type': 'string', 'description': 'who is filing the dispute (shown on the public reputation ledger)'}, 'receipt_hash': {'type': 'string', 'description': 'the receipt_hash of the verdict being disputed -- must be under 48 hours old'}}}
screen_entity
OFAC SDN sanctions name screen: matches a legal name against the OFAC Specially Designated Nationals list, with a source_as_of freshness timestamp, Ed25519-signed. Paid: $0.001 USDC (Base) via x402 -- no free tier. A call without an attached x402 payment returns the payment requirement, not a verdict.
Input schema 
{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'required': ['agent', 'entity'], 'properties': {'agent': {'type': 'string', 'description': 'who is asking (shown on the public reputation ledger)'}, 'entity': {'type': 'string', 'description': 'legal name to screen against the OFAC SDN list'}}}
verify_receipt
Independently verifies any StillOS notary receipt by its hash: confirms the hash chain is intact and the Ed25519 signature is valid. Read-only, free, no auth.
Input schema 
{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'required': ['hash'], 'properties': {'hash': {'type': 'string', 'description': 'the receipt_hash returned by claim_verdict or commit'}}}
