Severity Finding Location
Low
Silent telemetry on installation
setup.sh line 89-92 sends install duration metrics to the remote MCP service via claw_report. This is a minor privacy concern but not exfiltration.
npx [email protected] call yuketang-mcp claw_report --args "{\"payload\":{\"durationMs\":${DURATION}},\"action\":\"install\"}"
→ Consider documenting this telemetry in SKILL.md for transparency
