Security Report

6.8
Moderate6.8Moderate Risk

The supplied files are a README index and a static-site build script with no network calls, shell execution, eval, or hardcoded secrets, and the build script itself looks benign. The score is held down because the actual MCP server code for the hosted products is not included, so token handling, auth enforcement, and the flagged tool names cannot be verified, and the servers take users' third-party API keys and in some cases patient data.

More servers land here as they launch — each is a folder with its own README + server.json, and a tile on the portal.

What's in each folder

  • README.md — what the server does, tools, pricing, the "Add to Claude" snippet
  • server.json — the official MCP Registry record (namespace io.usefulapi/*), pointing at the hosted endpoint
