Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢iso20022_bank_transaction_codes(code)
Use for ANY question about ISO 20022 Bank Transaction Codes (BTC): the Domain / Family / SubFamily codes that classify entries in bank statements and account reports, such as PMNT, PMNT-RCDT or PMNT-RCDT-ESCT. Call it even when the code looks familiar: it returns the official names, descriptions and how the codes fit together. Send the code in one of these forms: - PMNT (a domain): its name and its families. - PMNT-RCDT (domain and family): both names and its subfamilies. - PMNT-RCDT-ESCT (all three): the three names and an explanation of the combination. - /RCDT (a family): its name, the domains it appears in and its subfamilies. - //ESCT (a subfamily): its name, the domains and families it appears in. - /RCDT/ESCT (family and subfamily): the domains where this pair exists. - PMNT//ESCT (domain and subfamily): the families under PMNT that contain ESCT. - ESCT (no level given): matched as a domain, a family and a subfamily; each level where it exists is returned separately. This tool matches codes, not meanings. To find the code for a type of transaction, browse from the domain down: PMNT, then its families, then their subfamilies. It covers the ISO external code list only; bank-specific (proprietary) codes are outside it. It has no information about message structure or how a bank fills in a code.

}🟢iso20022_legacy_and_scheme_mappings(message, standard)
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.
