Install x402 mcp server in Grok
.mcp.json (in your project root)
{
"mcpServers": {
"x402-mcp-server": {
"type": "stdio",
"command": "npx",
"args": [
"-y",
"x402-mcp-server_by_milza"
],
"env": {
"BASE_PRIVATE_KEY": "<BASE_PRIVATE_KEY>"
}
}
}
}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
