SEC Rule 15c3-3 Exhibit A customer reserve formula: credit items against allowable debit items (margin-account 1% haircut, 30-day failed-to-deliver aging exclusion) to a reserve requirement and deposit-sufficiency verdict. Simplified over a representative subset of Exhibit A line items — the receipt attests our computation over the inputs supplied, not an audit of those inputs or a determination of regulatory compliance.
Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.
Run the AINumbers MCP tool `compute_15c3_3_reserve`. Task: SEC Rule 15c3-3 Exhibit A customer reserve formula: credit items (customer free credit balances, margin credit balances, payables) against allowable debit items (margin-account debits with the 1% collateral haircut, failed-to-deliver debits with the 30-day aging exclusion, other allowable debits) to a reserve requirement, deposit-sufficiency verdict, and line-item receipt.
Call it with arguments: {"policy_parameters":{"credit_items":[{"label":"Free credit balances","category":"free_credit_balances","amount_musd":40},{"label":"Margin credit balances","category":"margin_credit_balances","amount_musd":12},{"label":"Payable from securities loaned using customer securities","category":"payable_from_securities_loaned_using_customer_securities","amount_musd":5}],"debit_items":[{"label":"Margin account debits","category":"margin_account_debit","amount_musd":20,"aging_days":5},{"label":"Securities failed to deliver (10d)","category":"securities_failed_to_deliver","amount_musd":3,"aging_days":10}],"reserve_account_balance_musd":35,"pab_variant":false}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
