01 · Install Trestle

Claude Code

claude mcp add toro-guapo-trestle -- npx -y @trestlescan/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "toro-guapo-trestle": {
      "command": "npx",
      "args": [
        "-y",
        "@trestlescan/mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

npm package @trestlescan/mcp - the @trestlescan scope differs from the repo owner (toro-guapo); confirm it's the project's official package

registry vendor namespace com.trestlescan - domain-verified with the official MCP registry
