Payment Intelligence MCP server

Payment Intelligence: ISO 20022 tools for AI assistants

Offline ISO 20022 tools for payment operations, investigations and migration teams, packaged for Claude Code, OpenAI Codex, GitHub Copilot, VS Code, Gemini CLI, Cursor and any MCP client. It is built on the same libraries as the Payment Intelligence Modules browser suite.

Nothing leaves your machine. The plugin runs a local MCP server over stdio. It makes no network calls, sends no telemetry and has no account. It only reads files you name, and writes only the scrubbed copy you ask for.

We don't provide reference data. The plugin works on your own. No SwiftRef, BIC Directory or SSI data is shipped, sold or downloaded. Your institution already licenses that data; the tools read the files you point them at, on your machine: your own reference files, your own SSI file and your own payment messages. It is provider-agnostic:

• SWIFTRef, current format: unzipped BIC Directory and Payments Directory folders (IDENTIFIERS including historical, PARTICIPANTS and RELATIONSHIPS files; layouts are read from the STRUCTURES file in the same download).
• SWIFTRef, legacy products: BIC Plus, BIC Directory 2018, Bank Directory Plus, IBAN Plus, SEPA routing, Reach Plus, gpi, and SSI Plus.
• Any other provider or in-house system: CSV/TSV exports. Common column names are recognised automatically, column_map covers any other layout, and any column it cannot map is listed in the result, so there is no lock-in to one data vendor.

The only data built in is public format rules: the SWIFT IBAN Registry structures, ISO country and currency codes, and a short list of ISO status and reason codes.

What you can ask

• "Explain this pacs.008 / pacs.004 / camt.053."
• "Scrub payments/batch-0412.xml before I send it to the vendor."
• "Why was this payment returned? Here are the pacs.008, pacs.002 and pacs.004."
• "Here is the camt.110 we received and the original pacs.008. What are they asking, and has it been answered?"
• "What did the responder confirm in this camt.111?" or "What do these Tracker notifications say about our case?"
• "Is DE89 3704 0044 0532 0130 00 a valid IBAN?" or "Build a French IBAN from these bank and account numbers."
• "Is this message CBPR+ ready?"
• "Validate our SSI file ssi/master.tsv." or "Does this pacs.009 pay Nova through the correspondent in our SSI file?"
• "Look up DEUTDEFF in our BIC Directory at ~/swiftref/2026-02." or "Which BIC does sort code 400501 route to?"
• "Check this pacs.009 against the SSIs in our Payments Directory RELATIONSHIPS file."
