Untap for Grok

io.github.aneduaim/untap-mcp

UK refunds inside your AI assistant: train delays, flights, TfL, parking. Made in London.

client:Grok transport:streamable-http

Install Untap in Grok

.mcp.json (in your project root) 

{
  "mcpServers": {
    "untap-mcp": {
      "type": "http",
      "url": "https://untap.money/api/mcp"
    }
  }
}

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
