Construction: Change Order Audit with Claude Code: MCP Tool Boundary
A production playbook for change order audit in construction operations using Claude Code: mcp tool boundary, run-scoped inputs, logs, typed results, and artifacts.
Audience: Construction finance and project controls teams
The problem
Construction finance and project controls teams need change order audit to run repeatedly against change orders, contracts, invoices, schedules, and field reports. In construction 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 change order audit, 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 change order audit, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
