Ariadne Nexus OFAC Sanctions & Escrow Safe-Harbor Oracle MCP Server

Calculates institutional RWA clearing house take-rates (in basis points and USD), cross-chain settlement bridge tolls, platform SaaS subscription fees, and net annual clearing cost projections across Ariadne Nexus membership tiers. Use when: estimating monthly or annual clearing fees, basis-point take-rates, and cross-chain bridge settlement costs before syndicating an RWA vault or selecting an institutional billing tier. Do not use when: provisioning an API key or generating a live Stripe checkout session (use provision_agent_key instead), or valuing bond CUSIPs (use get_cusip_valuation instead). Behavior: Free, open-access, read-only deterministic calculator ($0.00 USD; requires no apiKey or paymentToken and performs no external network calls or billing mutations).

Issues a KMS-attested Statutory Closing Safe-Harbor Certificate combining OFAC SDN Jaro-Winkler/LEI Merkle proof screening, multi-factor hedonic collateral fair-value attestation, and HUD-1 Line 1109 pass-through fee calculation ($95 flat or 10 bps on escrow notional). Use when: an escrow agent, title company, aviation/maritime closing attorney, or autonomous clearing agent requires a signed compliance and fair-value certificate prior to wire disbursement. Do not use when: you only need a standalone counterparty name check without collateral valuation or HUD-1 closing fee calculation (use screen_ofac_entity instead). Behavior: Read-only, deterministic, idempotent compliance and valuation oracle with zero external side effects.

Returns pricing specifications, monthly query quotas, rate limits (RPM), 1-click Stripe Checkout links (starting at $10/mo MCP Builder Pass up to $9,500/yr FAR 13.2 GPC & Unlimited Closing Blanket licenses), Stripe Projects CLI commands (`stripe provision ariadnenexus`), and optional live Stripe Checkout session URLs (`mint_stripe_session: true`) for obtaining a live Ariadne Nexus Developer API key (`nexus_live_...`). Use when: an agent, developer, escrow attorney, or litigation desk needs pricing comparisons or a direct clickable Stripe Checkout URL after encountering a paymentChallenge on paid tools. Do not use when: redeeming an already-paid Stripe Checkout `cs_...` session ID for its API key (use redeem_checkout_session instead), or estimating basis-point RWA clearing take-rates (use calculate_clearing_fee instead). Behavior: Free discovery and checkout-link generator ($0.00 USD). Does not charge any payment method on invocation; billing only occurs if the human completes payment at the returned Stripe Checkout URL.

Verifies a completed Stripe Checkout session (`cs_...`) directly against Ariadne Nexus billing and deterministically returns the buyer’s live HMAC-signed `nexus_live_...` API key, monthly quota, and 1-click Cursor / VS Code / Claude Code installation links. Use when: a user has just completed payment at Stripe Checkout and wants to immediately claim and activate their `nexus_live_...` API key inside Claude, Cursor, VS Code, or an autonomous agent without waiting for email delivery. Do not use when: the user has not yet paid or needs a checkout link first (use provision_agent_key instead). Behavior: Free, read-only, deterministic verification and HMAC credential derivation ($0.00 USD; idempotent across repeated invocations for the same paid `cs_...` session ID).

Screens a corporate entity or individual counterparty against the U.S. Treasury OFAC Specially Designated Nationals (SDN) and consolidated sanctions registries using exact identifier matching (LEI/CIK/CRN) and Jaro-Winkler fuzzy phonetic resolution, returning a compliance verdict and SHA-256 Merkle audit proof. Use when: verifying whether a specific company, vessel, wallet counterparty, or individual is sanctioned before onboarding or settlement. Do not use when: retrieving macro-level weekly sanctions policy trends (use get_sovereign_policy_brief instead) or drafting regulatory comment letters on FinCEN/OFAC rulemakings (use synthesize_regulatory_docket instead). Behavior: Read-only, deterministic compliance check ($0.50 USD per call via HTTP header x-api-key or x-payment-token; returns an x402/MPP paymentChallenge without charging if credentials are omitted).

Generates the Weekly Sovereign Macro-Prudential & Sanctions Monitor for Federal Reserve (FOMC / Financial Stability), U.S. Treasury (OFR / OFAC / FinCEN), and SEC DERA policy desks, combining Dual-Track monetary stability indicators (10Y-3M yield curve inversion, FINRA TRACE G-SIB credit spread dislocations, H.8 bank credit impulse) and autonomous x402 sanctions enforcement telemetry. Use when: synthesizing macro-prudential systemic risk briefings, monitoring aggregate sanctions enforcement trends, or evaluating FAR Subpart 13.2 ($9,500 GPC Micro-Purchase) policy data procurement options. Do not use when: screening a specific individual or corporate counterparty against the OFAC SDN list (use screen_ofac_entity instead), or drafting a formal APA 5 U.S.C. § 553 public comment letter for a specific agency rulemaking docket (use synthesize_regulatory_docket instead). Behavior: Read-only, deterministic intelligence report generator ($1.00 USD per call via HTTP header x-api-key or x-payment-token; returns an x402/MPP paymentChallenge without charging if credentials are omitted).
