dual-claude-json-config-drift-detection-via-mcp-list-count

State drift between /home/claude/.claude.json and /root/.claude.json can be detected by running claude mcp list from both user contexts and comparing server counts. A discrepancy (e.g., 8 vs 7) indicates a registration was added to one config but not mirrored. The canonical dual-config rule requires both files to be identical; any jq write to one must be followed by an identical write (via sudo) to the other in the same operation.
