Vexor for Grok

Install Vexor in Grok

.mcp.json (in your project root)

{
  "mcpServers": {
    "vexor": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "vexor"
      ],
      "env": {
        "VEXOR_API_KEY": "<VEXOR_API_KEY>",
        "VEXOR_REMOTE_RERANK_API_KEY": "<VEXOR_REMOTE_RERANK_API_KEY>",
        "VEXOR_CONFIG_JSON": "<VEXOR_CONFIG_JSON>"
      }
    }
  }
}

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
