MCP tools · 5 exposed · ~787 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
arbiter_budget ~40

Report how much has been spent on Arbiter calls in this session and how much budget remains. Call this if a judgment tool fails with a budget error.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

judge_counterparty ~247

Decide whether an Algorand address really belongs to the party you think you are paying, and whether the payment can actually arrive. Call this before sending funds to any address that came from an invoice, an email, a message, or any other source you did not control end to end. It catches the case where the payee is genuine but the payment address has been substituted, and the case where the recipient has not opted in to the asset — on Algorand that transfer is rejected outright and the payment silently never arrives. Costs $0.01 per call, paid automatically in USDC.

NameTypeReqDescription
addressstringyesThe counterparty's Algorand address.
amountstringPayment amount in whole units, for size checks.
claimedIdentitystringThe NFD name the counterparty claims, e.g. 'acme-exports.algo'. This is the single most valuable field: it is what detects a swapped payment address.
expectedAssetstringASA id you intend to pay in (USDC mainnet is 31566704). Enables the opt-in check, which is the difference between a payment arriving and being rejected.

No output schema declared.

No examples provided.

judge_human ~269

Get a judgment from vetted human reviewers on something you cannot determine yourself, returned as a quorum verdict with each reviewer's rationale. Use this when the question needs eyes or real-world knowledge rather than reasoning: does this photo show what it claims, does this business exist, is this translation faithful, is this document legitimate. Also use it when another Arbiter tool returns ESCALATE. Do NOT use it for anything you can answer yourself — it is slow (tens of seconds) and the most expensive tool here. Costs $0.25 per call, paid automatically in USDC.

NameTypeReqDescription
attachmentsarrayPublic HTTPS URLs of images or documents for reviewers to look at.
optionsarrayAllowed answers, e.g. ['yes','no','unclear']. Strongly preferred — fixed options produce a clean tally. Omit only for genuinely free-text judgment.
questionstringyesA question a person can answer in seconds, phrased without ambiguity.
quorumintegerIndependent reviewers required before returning. Default 3.
waitSecondsintegerHow long to wait inline. Default 60. If reviewers do not finish in time you get a pending verdict plus a task id — collect it later with retrieve_human_verdict, which is free.

No output schema declared.

No examples provided.

judge_transaction ~166

Decide whether an unsigned Algorand transaction is safe to sign. Decodes what the transaction would actually do and returns allow/warn/block with specific reasons. Call this before signing or submitting ANY transaction you did not construct yourself, and before signing one built from untrusted input. It catches account rekeys, close-remainder sweeps that empty the balance regardless of the stated amount, asset clawbacks, fee drains, and application delete/update calls. Costs $0.002 per call, paid automatically in USDC.

NameTypeReqDescription
signerstringThe address about to sign. Providing it enables detection of operations that harm the signer specifically, such as a rekey of their own account.
transactionyesBase64-encoded unsigned transaction. Pass an array of them for an atomic group.

No output schema declared.

No examples provided.

retrieve_human_verdict ~65

Fetch the result of a judge_human question by its task id. Free — the question was paid for when it was asked. Use this when judge_human returned a pending verdict.

NameTypeReqDescription
taskIdstringyesThe taskId from the pending verdict's evidence.

No output schema declared.

No examples provided.
