Customer Data Redaction with Claude Code: MCP Tool Boundary
A production playbook for customer data redaction in cross-industry operations using Claude Code: mcp tool boundary, run-scoped inputs, logs, typed results, and artifacts.
Audience: Privacy and support teams
The problem
Privacy and support teams need customer data redaction to run repeatedly against documents, logs, screenshots, and redaction policy. In cross-industry 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 customer data redaction, 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 customer data redaction, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
