"url": "https://mcp.zovo.one/mcp/exchange-rates"
}
}
}-

Save the file and restart Grok.

If it does not appear, check that exchange rates is connected and that you are looking at its prompts 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 prompt, other clients
Read from the server itself, by connecting to it and calling prompts/list on 24 September 2026.
A listing does not declare its prompts, 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 prompt's arguments.
