What is the MCP Fx Audit MCP server?

Most knowledge and memory work still happens through a UI a human drives. MCP Fx Audit MCP server moves it into the conversation instead. The world's first Model Context Protocol server for foreign exchange forensic auditing. Any AI agent (Claude, Perplexity, Cursor, Copilot) can audit FX transactions against mid-market rates in real time and generate FINTRAC-certified.

The short version

iPayX Protocol (11850091 Canada Inc.) is the only rail-agnostic FX forensic audit layer for B2B payments. We audit hidden costs regardless of payment rail - SWIFT, SEPA, Stablecoin, or Card.

The tools it exposes

The server publishes 5 tools. What each one is for:

  • check_fx_rate — Get the current mid-market exchange rate for any currency pair
  • audit_transaction — Audit a specific FX transaction. Compares the rate your bank applied against the real mid-market rate. Returns the hidden spread in basis points, a
  • full_forensic_report — Generate a complete forensic FX audit report suitable for legal proceedings, CFO review, or FINTRAC compliance documentation. Includes spread
  • compare_fx_sources — Compare FX rates from multiple sources simultaneously (Twelve Data, Open Exchange Rates). Detects discrepancies and identifies the most favorable
  • Perplexity — Settings → MCP Connectors → Add Remote → paste URL: https://wild-bird-a412.ybolduc.workers.dev/mcp

Getting it running

The server ships on npm as smithery, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

How it compares

This sits in the knowledge and memory group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. MCP Fx Audit's toolset — check_fx_rate, audit_transaction, full_forensic_report and 2 more — is a fair guide to whether it matches your workflow. It is maintained by ipayx-technologies; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
