Grok Filesystem edit_file

Add Filesystem to Grok

1. 01

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

{
  "mcpServers": {
    "server-filesystem": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem"
      ]
    }
  }
}

2. 02

   Save the file and restart Grok.

3. 03

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

4. 04

   If nothing happens, check the server is running and that Filesystem'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
