Marrow vs Who Tb
A side-by-side look at the Marrow and Who Tb 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 Who Tb for biology, medicine and bioinformatics as a local process. You can also run both side by side in one mcpServers block.
