| Tool | Description | Behaviour |
|---|---|---|
| iso20022_legacy_and_scheme_mappings | Use for ANY question about what replaces or corresponds to a legacy payment message (SWIFT MT such as MT103, MT202, MT940; NACHA; CHAPS), or which payment schemes use an ISO 20022 message (pacs.008, pain.001, pain.008, camt.053; SEPA, NPP, CHAPS, Lynx, CIPS and others). Call it even when the answer seems well known: it returns sourced, current mappings with status and caveats. For "which schemes use X", call once with only the message: the response lists every recorded scheme (without descriptions, to keep it compact). Omit `standard` unless the user names one scheme; with `standard`, the response includes that scheme's description. - Legacy input (MT103, 940, ACH Statement): returns its ISO 20022 equivalent(s) in legacy_equivalents. - ISO 20022 input (pacs.008): returns legacy_equivalents (legacy messages that map to it) and used_by_schemes (schemes that use it). Mappings are message-level only; this tool does not map individual fields and has no information about a message's structure, elements or rules. Do not cite it for those. ISO 20022 messages that have been retired are returned flagged with iso20022_deactivated_in, not hidden. | Read-only |
