Pacs008 MCP vs Clawpay MCP

get_required_fields

List only the required input field names for a pacs message type. Use this for a quick checklist of the mandatory columns before building payment records. For full type/format constraints (not just which fields are required), call ``get_input_schema`` instead. Args: message_type: A supported ISO 20022 pacs message type.

get_input_schema

Return the full JSON Schema for a message type's flat input record. Use this to learn every field, its type, and its constraints before assembling records, or to drive a form/UI. For just the required-field names use ``get_required_fields``; to check records against this schema use ``validate_records``. Args: message_type: A supported ISO 20022 pacs message type.

validate_records

Validate flat payment records against a message type's JSON Schema. Use this before ``generate_message`` to catch structural/type errors per record and get a row-by-row error report. This checks JSON-Schema shape only; to check a batch against a rail's usage guidelines use ``validate_scheme``. Returns a report ``{"is_valid": bool, "total": int, "valid": int, "errors": [...]}``. Args: message_type: A supported ISO 20022 pacs message type. records: One or more flat payment records to validate.

validate_scheme

Validate payment records against a scheme's usage-guideline rules. Use this to check a batch against a rail's rulebook (CBPR+, HVPS+, Fedwire, CHAPS, T2 RTGS, SCT Inst) -- charge-bearer restrictions, UETR presence, remittance-info length, and per-message transaction cardinality. This is complementary to ``validate_records`` (JSON-Schema shape). Returns ``{"scheme": str, "is_valid": bool, "total": int, "violations": [...]}``. Args: scheme: A registered scheme profile name (see ``list_schemes``). records: One or more flat payment records to check.

generate_message

Generate a validated ISO 20022 pacs XML message from in-memory records. This is the primary generation tool: pass payment records you already hold in memory and receive an XSD-validated XML document; no file is written. Run ``validate_records`` first to surface record-level errors, and ``list_message_types`` to confirm the ``message_type`` string. Returns the validated XML document as a string, or an ``{"error": ...}`` payload (serialized) if generation fails. Args: message_type: A supported ISO 20022 pacs message type. records: One or more flat payment records.

validate_xml

Validate a raw XML string against a message type's bundled XSD. Use this to check an externally produced XML document against the official ISO 20022 schema. To generate a document that is already XSD-validated, use ``generate_message`` instead. Returns ``{"message_type": str, "is_valid": bool}``. Args: message_type: A supported ISO 20022 pacs message type. xml: The raw XML document to validate.

parse_message

Parse and classify an inbound ISO 20022 XML message. Use this on the receiving side to identify what a message is -- its ``msg_def_idr`` (e.g. ``pacs.002.001.10``), family, version, and any Business Application Header -- before processing it. Handles both bare ``Document`` messages and BAH-wrapped envelopes. Returns a dict with ``msg_def_idr``, ``msg_family``, ``version``, ``root_local_name``, ``namespace_uri``, ``envelope_wrapped`` and ``bah``. Args: xml: The raw inbound XML message.

convert_mt103

Convert a legacy SWIFT MT103 into pacs.008-ready flat records. This is the SWIFT MT-to-MX migration path (correspondent-banking MT103 coexistence with ISO 20022 ends November 2025): parse an MT103 text payload and get back the flat pacs.008 record(s) that can be fed straight into ``validate_records`` / ``generate_message``. An MT103 carries exactly one transfer, so the ``records`` list always holds a single record. No file is read or written. Returns ``{"message_type": "pacs.008.001.08", "records": [{...}]}`` with the parsed flat record, or an ``{"error": ...}`` payload if the MT103 is missing a mandatory field (``:20:``, ``:32A:``, beneficiary) or malformed. Args: mt103_text: The MT103 payload as a string.

classify_address

Classify a postal address as structured, hybrid, or unstructured. Use this to see where an address stands against the SWIFT structured-address rule: ``structured`` (town + country + structured detail, no free-form lines), ``hybrid`` (town + country + 1-2 free-form ``adr_line`` lines, the minimum CBPR+ UG2026 bar), or ``unstructured`` (free-form only — rejected from the cliff date). To check acceptability under a policy use ``validate_address``; to upgrade legacy lines use ``repair_address``. Returns ``{"classification": str, "is_structured": bool, "is_hybrid": bool, "is_unstructured": bool, "has_structured_fields": bool}`` or an ``{"error": ...}`` payload. Args: address: The postal address as a dict of snake_case fields.
