Overview

The Model Context Protocol standardizes how agents connect to tools and data. It is silent on whether they should. Four risk areas a regulated institution should resolve before agents get tools.¹

What it covers

• Security: the attack surface is the tool description
• Auditability: reconstruct the decision behind the call
• Privacy and residency: context is a data flow
• Maturity: plan for a protocol that keeps moving
• A worked example: onboarding one server
• Use the risk framework you already have

Bottom line

MCP solves connectivity. Trust is still an architecture problem: identity, policy, audit and a governed server catalog decide whether a bank can use it safely.

• If you can’t prove why an AI wrote it, you can’t ship it - Shipping AI-generated code without recording where it came from is unmanaged risk. Regulated teams need deterministic provenance for non-deterministic models: line-level attribution, Git-native session history and AI bills of materials.
• Model is a tool, harness is the strategy - Handing an AI agent a production codebase without a harness is like putting a teenager in a sports car with no dual brakes. Deterministic guardrails and sensors, owned as a platform, are what make agents safe to scale.
• Agent-first data architecture: five principles - Data platforms built for people asking questions will strain when the main consumer is software taking actions. Five principles for designing data platforms where agents are first-class users, and why an open lakehouse helps.
• Designing an enterprise MCP registry: the control point agents need - As agents multiply, every enterprise needs an authoritative directory of the tools they can call. What a governed MCP registry must do, what the official registry leaves to you, and the mistakes to avoid.
• Securing AI agents: identity, not secrets - Agents act on their own, at machine speed, across many systems. Static credentials and perimeter thinking don’t hold up. Attested identity, explicit delegation and policy enforced outside the model do.
• Enterprise Generative AI Architecture - An enterprise-grade Generative AI reference architecture: a governed path from experiment to production, adopted as the reference model across business lines.
