Clinicaltrials MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Clinicaltrials MCP?

Clinicaltrials MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @mrfentmen/clinicaltrials-mcp.

How do I connect Clinicaltrials MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @mrfentmen/clinicaltrials-mcp straight from npm; nothing to host, nothing to sign up for.

Is Clinicaltrials MCP open source?

We cannot say either way: written in TypeScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
