Finance: Board Metrics Pack Validation with Claude Code: MCP Tool Boundary

A production playbook for board metrics pack validation in finance operations using Claude Code: mcp tool boundary, run-scoped inputs, logs, typed results, and artifacts.

Audience: Finance and founder teams preparing board materials

The problem

Finance and founder teams preparing board materials need board metrics pack validation to run repeatedly against metric exports, spreadsheets, CRM reports, finance models, and deck claims. In finance 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 board metrics pack validation, 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 board metrics pack validation, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
