familylink-mcp

MCP server for Google Family Link. Lets an AI assistant read and change the parental controls of your supervised children: downtime (bedtime), daily screen time limits, app rules, device lock, extra time and contacts.

It talks to the same private API as familylink.google.com, using the Google session of the parent account in Chrome. No browser automation.

Unofficial. The API is not public and can change without notice.

Setup

Requirements: uv, Google Chrome signed in to the parent account (open familylink.google.com once). On macOS the first run asks for Keychain access to "Chrome Safe Storage" so the cookies can be read.

  "mcpServers": {
    "familylink": {

      "args": ["--from", "git+https://github.com/jantoebes/familylink-mcp", "familylink-mcp"]
    }
  }
}

Not (yet) supported

School time, website allow/block lists, Google Play and YouTube settings, and changing device restrictions are read-only or missing. Apple Screen Time has no API and is out of scope.
