Install Nephyr Backtest in Grok

.mcp.json (in your project root) 

{
  "mcpServers": {
    "nephyr-backtest": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "nephyr-backtest"
      ]
    }
  }
}

Grok Build reads Claude Code's .mcp.json and Claude Desktop's config unchanged, so a server you have already set up there needs nothing new. The Grok web app and X integration do not take custom servers. Grok docs
