Install r3 in Grok
.mcp.json (in your project root)
{
"mcpServers": {
"r3": {
"type": "stdio",
"command": "npx",
"args": [
"-y",
"@n3wth/r3"
],
"env": {
"MEM0_API_KEY": "<MEM0_API_KEY>",
"REDIS_URL": "<REDIS_URL>"
}
}
}
}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
