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_ltv_ratios`. Task: Loan-to-value, combined LTV, and home-equity combined LTV per Fannie Mae Selling Guide B2-1.1-03 and Freddie Mac Single-Family Seller/Servicer Guide 5401.1.
Call it with arguments: {"policy_parameters":{"appraised_value":500000,"sales_price":490000,"first_lien_amount":392000,"subordinate_lien_amount":0,"heloc_credit_limit":0,"transaction_type":"purchase"}}
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.
