Security Report

8.2
Low Risk8.2Low Risk

This is a static site builder and manifest codegen tool for a hosted MCP server registry. The code is well-structured with proper input validation, no hardcoded credentials, and safe file operations. Minor code quality issues around exception handling do not significantly impact security; permissions (file I/O, no network calls) are appropriate for its build-time purpose.

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
