OpenChainGraph tools for the SEC US Treasury clearing mandate (Rule 17ad-22). A larger share of UST cash and repo — bilateral and triparty — must centrally clear through a covered clearing agency. The market is now multi-CCP (FICC/DTCC, CME Securities Clearing, ICE Clear Credit, LCH applying). These tools cover access-model selection, FICC VaR margin & netting, FICC-CME cross-margining, capital relief, liquidity, collateral, onboarding, and settlement integrity — ~85% reuse of the capital-markets stack. Client-side, zero-egress, hash-anchored; the four new tools are agent-native over MCP.
All four emit verifiable OpenChainGraph v0.4 artifacts and compute server-side over MCP (Compute Binding). Educational models — not clearing advice.
Each chains the new tools with the existing capital-markets + crypto-integrity stack; the terminal artifact carries the full provenance chain and can be exported via export_artifact.
