A side-by-side look at the Backwork and Medical Codes MCP Server MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Backwork for biology & bioinformatics work as a local process; choose Medical Codes MCP Server for biology & bioinformatics as a local process. You can also run both side by side in one mcpServers block.
