io.github.pachote/nira-repl

Secure code execution sandbox for Claude — run Python, JavaScript, and shell commands

client:Grok transport:stdio runtime:pypi

Install NIRA REPL MCP in Grok

.mcp.json (in your project root)

{
  "mcpServers": {
    "nira-repl": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "nira-repl"
      ]
    }
  }
}

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
