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