    Server tool list (5)

    Raw names from tools/list. Only developers need these.

    describe_verify_evidenceDescribe when deterministic verification is useful, when it is not, free request validation, recipes, limits, and the explicit paid MCP path.
    get_revenue_goal_statusRead the active revenue goal, measured funnel, contribution margin, and the next bounded improvement recommendation. This tool never changes price, spends funds, or sends messages.
    quote_verify_evidenceValidate a complete verification request and return a free quote when the margin policy passes.
    prepare_verify_evidence_purchaseAfter a successful free precheck, create or reuse a bound quote and return the exact HTTP request that will produce the x402 challenge. Do not pay until the binding, price, network, asset, payTo, and expiry match local policy.
    verify_evidenceRun deterministic checks and return Ed25519-signed evidence after one explicitly authorized x402 payment. A free precheck receipt and a matching bound payment requirement are required before signing.
