## MCP tools (5)

### `claim_verdict` (~143 tokens)

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 parameters:

- `agent` (string, required): who is asking (shown on the public reputation ledger)
- `claim` (string, required): the claim in plain language, e.g. "PR #42 on owner/repo is merged"
- `resolver` (object, required): which external source resolves this claim

### `verify_receipt` (~62 tokens)

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 parameters:

- `hash` (string, required): the receipt_hash returned by claim_verdict or commit

### `file_dispute` (~154 tokens)

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 parameters:

- `agent` (string, required): who is filing the dispute (shown on the public reputation ledger)
- `receipt_hash` (string, required): the receipt_hash of the verdict being disputed — must be under 48 hours old

### `screen_entity` (~116 tokens)

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 parameters:

- `agent` (string, required): who is asking (shown on the public reputation ledger)
- `entity` (string, required): legal name to screen against the OFAC SDN list

### `distress_score` (~133 tokens)

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 parameters:

- `agent` (string, required): who is asking (shown on the public reputation ledger)
- `ticker` (string, required): equity ticker to score, e.g. "AAPL"
