Retail Vendor Chargeback Review with Claude Code: MCP Tool Boundary

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

Audience: Retail operations and supplier teams

The problem

Retail operations and supplier teams need retail vendor chargeback review to run repeatedly against chargeback notices, POs, shipment records, routing guides, and dispute evidence. In retail 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 retail vendor chargeback 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 retail vendor chargeback review, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
