Grok FactGrid (Renamed to FactReason) factreason_subscribe_spec_changes

Add FactGrid (Renamed to FactReason) to Grok

1. 01

   Open .mcp.json (in your project root) and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "factgrid": {
      "type": "http",
      "url": "https://factgrid.co.uk/mcp"
    }
  }
}

2. 02

   Save the file and restart Grok.

3. 03

   Ask for something factreason_subscribe_spec_changes does. Grok lists the server's tools on connect and calls factreason_subscribe_spec_changes itself — you do not invoke it by name.

4. 04

   If nothing happens, check the server is running and that FactGrid (Renamed to FactReason)'s identifier in your config matches the one above exactly.

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
