A side-by-side look at the Clinicaltrialsgov MCP Server and Medical 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 Medical MCP for biology, medicine and bioinformatics as a local process. You can also run both side by side in one mcpServers block.
clinicaltrials_search_studies, clinicaltrials_get_study_record, clinicaltrials_get_study_count.Rows where the two servers differ are marked.
