camt053-mcp — ISO 20022 Bank Statement Parser

Parse, validate, and reconcile ISO 20022 camt.053 bank-to-customer statements from any MCP client. Part of the ISO 20022 MCP Suite — the emerging standard library for financial messaging in AI agent workflows.

What It Does for Operators

If your business receives camt.053 statements from banks (standard in EU, UK, CH, and migrating globally under CBPR+), this server lets AI agents:

  • Parse statements — Extract transactions, balances, and metadata from camt.053 XML
  • Validate against XSD — Ensure statements conform to ISO 20022 schema
  • Reconcile entries — Match statement entries against internal records
  • Generate reversing entries — One-shot XML generation for corrections/reversals
  • Export to accounting — Native journal export to Xero and QuickBooks Online
  • CBPR+ readiness check — November 2026 cliff assessment for cross-border payments

Operator Use Cases

  1. Finance Teams — Automate monthly bank statement reconciliation. Feed camt.053 files to your AI agent and get matched/unmatched entries, exported to Xero/QBO.

  2. Treasury Operations — Validate incoming statements for CBPR+ readiness before the November 2026 deadline. Flag non-compliant fields.

  3. Fintech Builders — Use the parsing + validation pipeline as a building block for AI-powered banking workflows.

ISO 20022 MCP Suite

CorpusIQ Angle

ISO 20022 is the global standard for financial messaging — every bank migration is underway with the CBPR+ deadline approaching. This MCP suite gives operators programmatic access to banking messages from AI agents. Pairs naturally with CorpusIQ's financial connectors (Stripe, QuickBooks, etc.) for end-to-end financial automation.

Limitations

  • Python-only
  • Requires camt.053 XML files as input — does not fetch statements from banks directly
  • Early-stage (1⭐). Test thoroughly before production use.
  • CBPR+ readiness checks reference November 2026 rules — will need updates post-deadline
