1. Executive Summary

This document defines the technical architecture for TMX Agentic Finance, an institutional-grade, secure, and interoperable Agentic AI solution for the banking and financial sector.

The core architectural philosophy is "Secure Interoperability via MCP". We utilize a Secure MCP Gateway pattern to abstract the complexity of external integrations (Crypto Wallets, Core Banking, Third-party AI), allowing for a "Plug-and-Play" experience where financial institutions can extend capabilities without altering the core agent logic.

The system is designed with two key pillars:

  1. Flexible Agentic Intelligence: A highly customizable AI core that allows financial institutions to seamlessly integrate with the agentic system.
  2. Secure, Fixed Interoperability: A standardized, ISO 27001-aligned connectivity layer (via MCP) that handles the complexity of external blockchain and payment integrations, requiring minimal effort from the client's technical team.

1.1 Key Architectural

  1. Secure MCP Gateway (Aggregator Pattern) We utilize a Secure MCP Gateway to abstract the complexity of external integrations (Crypto Wallets, Core Banking, Third-party AI). This provides a "Plug-and-Play" experience where the client connects via standard APIs without needing to manage the underlying infrastructure of every vendor.
  2. Custom Core Banking Sidecar We implement a Custom Core Banking Adapter (Sidecar) for each client. This creates a bridge between the client's existing APIs and our standard Agent interface, ensuring deep integration with minimal disruption to existing banking infrastructure.
  3. Enterprise-Grade Security The entire architecture is built to align with ISO 27001 standards, featuring strict PII redaction, "Trust-But-Verify" authentication, and isolated execution environments.
  4. Deployment Flexibility The system is designed to run in a dedicated AWS environment per client or On-Premise within the client's infrastructure, ensuring data sovereignty and compliance.

2. System Overview

2.1 High-Level Context

The system sits between the Bank's Client Channels (Mobile/Web) and the execution layers (Core Banking, Blockchain, 3rd Party APIs).
