Banking KYC File Review with Claude Code: MCP Tool Boundary

A production playbook for banking KYC file review in banking operations using Claude Code: mcp tool boundary, run-scoped inputs, logs, typed results, and artifacts.

Audience: Bank compliance teams reviewing customer onboarding

The problem

Bank compliance teams reviewing customer onboarding need banking KYC file review to run repeatedly against KYC forms, IDs, beneficial ownership records, sanctions notes, and risk policies. In banking operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.

Implementation path

Expose only the MCP tools needed for banking KYC file review, validate tool arguments, keep credentials in the owning service, and log each call outside the sandbox.

Tradeoffs and failure modes

Narrow tool boundaries reduce agent flexibility, but make the integration reviewable and supportable. For banking KYC file review, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
