How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "reviews": {
      "type": "http",
      "url": "https://usetested.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http usetested https://usetested.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://usetested.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
