# get_auditor — the auditor of an issuer and every change, with the receipt. Doors by what they resolve: - GTINs → https://gtinfetch.ai/mcp - Listed issuers (ticker, ISIN, LEI) → https://mcp.getissuer.ai/mcp - Receipts — the Record of Cleared Orders → https://mcp.rco-records.ai/mcp 1. get_auditor is the auditor of an issuer: an issuer by ticker, ISIN or LEI returns its auditor of record and every auditor change on the record, dated — each with its source page and read date, signed by the node of the issuer's market and receipted. Where a market's record does not carry the auditor, the answer says not_on_record for that market; nothing is inferred. 2.
