Metro 2 Credit-Reporting Record Lint

Checks a Metro 2 credit-reporting base-segment record against a PUBLIC SUBSET of the format: field presence/format, account-status and payment-rating code validity, and DOFD (date of first delinquency) cross-field consistency per FCRA 15 U.S.C. Sec 1681c(a)(4)-(5), including the 7-year-plus-180-day obsolescence check.

⚠ SUBSET NOTE: the CDIA Credit Reporting Resource Guide (CRRG) is a licensed proprietary document. This lint derives its field table and code lists ONLY from public sources (CFPB, CDIA's public Metro 2 overview, and the FCRA statute) and does not implement the full CRRG. J1/J2/K1-K4 segments are checked as presence flags only.

Ask your agent

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 `lint_metro2_record`. Task: Lint a Metro 2 credit-reporting base-segment record from a PUBLIC SUBSET of the format: field presence/format, account-status and payment-rating code validity, and DOFD (date of first delinquency) cross-field consistency per FCRA 15 U.S.C.
Call it with arguments: {"policy_parameters":{"account_type":"01","date_opened":"2018-03-15","date_reported":"2026-06-01","current_balance":0,"amount_past_due":0,"account_status":"13","payment_rating":"0","has_j1_segment":false,"has_j2_segment":false,"has_k_segment":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.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
