thingctx for Grok

Install thingctx in Grok

.mcp.json (in your project root)

{
  "mcpServers": {
    "thingctx": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "thingctx"
      ],
      "env": {
        "THINGCTX_POLICY": "<THINGCTX_POLICY>",
        "THINGCTX_APPROVE_WHEN": "<THINGCTX_APPROVE_WHEN>",
        "THINGCTX_FS_ROOT": "<THINGCTX_FS_ROOT>"
      }
    }
  }
}

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
