If it does not appear, check that X402-Broker Universal MCP Gateway & Multi-Agent Swarm Router is connected and that you are looking at its resources rather than its tools.
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
Same resource, other clients
Read from the server itself, by connecting to it and calling resources/list on 21 October 2026.
A listing does not declare its resources, so asking is the only way to know them, and this
is what the server actually offers rather than what its listing claims. Names only are
stored; connect the server for each resource's type and contents.
