Install modelmux in Grok
.mcp.json (in your project root)
{
"mcpServers": {
"modelmux": {
"type": "stdio",
"command": "uvx",
"args": [
"modelmux"
]
}
}
}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
