Debt Validation Notice Completeness Checker

Checks a debt-validation-notice content-element checklist against Regulation F 12 CFR 1006.34 (the Model Form B-1 element set) and computes the 30-day validation-period response-window math from a declared mailing date under a declared mailing-to-receipt assumption.

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 `check_debt_validation_notice`. Task: Check a debt-validation-notice content-element checklist against Regulation F 12 CFR 1006.34 (the Model Form B-1 element set) and computes the 30-day validation-period response-window math from a declared mailing date under a declared mailing-to-receipt assumption.
Call it with arguments: {"policy_parameters":{"inputs":{"notice_elements":[{"element":"debt-collector-name","status":"complete"},{"element":"consumer-name","status":"complete"},{"element":"account-number-or-reference","status":"complete"},{"element":"itemization-date","status":"complete"},{"element":"itemized-current-amount","status":"complete"},{"element":"itemization-breakdown","status":"complete"},{"element":"original-creditor-name-if-different","status":"complete"},{"element":"statement-of-dispute-rights-30-day","status":"complete"},{"element":"statement-of-right-to-original-creditor-info","status":"complete"},{"element":"model-form-b1-tear-off","status":"complete"}],"notice_mailed_date":"2026-07-01","mailing_assumption_days":5,"itemization_date":"2026-06-15"}}}
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.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
