A side-by-side look at the Marrow and Withings Health Data MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Marrow for biology, medicine and bioinformatics work over a hosted endpoint; choose Withings Health Data for biology, medicine and bioinformatics over a hosted endpoint. You can also run both side by side in one mcpServers block.
health_summary, list_metrics, metric_daily.get_hrv, get_sleep_summary, get_activity.Rows where the two servers differ are marked.
