Nintendo Switch Parental Controls

Nintendo Switch Parental Controls

An MCP (Model Context Protocol) server that exposes Nintendo Switch Parental Controls as AI-accessible tools. It wraps the pynintendoparental library and allows AI assistants to monitor and manage parental control settings on Nintendo Switch devices.

Features

• Authentication: Interactive Nintendo OAuth login flow via MCP tools, or pre-configured session token
• Device monitoring: List devices, view playtime, remaining time, sync status
• Playtime controls: Set daily limits, add extra time, configure per-day-of-week schedules
• Bedtime controls: Set bedtime alarms and end times
• Restriction controls: Set restriction mode (forced termination vs. alarm), content restriction levels
• Player tracking: View player profiles and today's app usage
• Application management: List apps, manage the allow-list (bypass content restrictions)

Prerequisites

• uv — install once, no Python or clone needed:

curl -LsSf https://astral.sh/uv/install.sh | sh

Authentication: Getting Your Nintendo Session Token

The server requires a Nintendo session token to access the Parental Controls API. You can obtain one in two ways:

Method 1: Interactive MCP Tool (Recommended for first-time setup)

1. Start the MCP server (see below)
2. Ask your AI assistant to call nintendo_get_login_url
3. Open the returned URL in your browser
4. Log in with your Nintendo Account
5. On the "Select this person" page, right-click the "Select this person" button and copy the link
6. Ask your AI assistant to call nintendo_complete_login with the copied URL
7. The tool will return your session token — save it!

Method 2: Manual (if you already have a token)

If you already have a session token, set it as an environment variable:

export NINTENDO_SESSION_TOKEN="your-token-here"

Saving Your Token

Once you have a session token, add it to your environment so you don't need to log in again:

# Add to your shell profile (~/.zshrc, ~/.bashrc, etc.)
export NINTENDO_SESSION_TOKEN="your-token-here"

# Or create a .env file (never commit this!)
echo 'NINTENDO_SESSION_TOKEN=your-token-here' >> .env

Note: Session tokens can expire. If you get authentication errors, repeat the login flow.

Running the Server

uvx --from switch-parental-controls mcp

No clone or install required — uvx fetches the package from PyPI and runs it in an isolated environment.

Environment Variables

Variable	Required	Default	Description
NINTENDO_SESSION_TOKEN	No*	—	Nintendo session token
NINTENDO_TIMEZONE	No	Europe/London	IANA timezone (e.g. America/New_York)
NINTENDO_LANG	No	en-GB	Language code (e.g. en-US)

*Required for any tool that accesses Nintendo data, unless you use the interactive login tools.

MCP Client Configuration

Add to your MCP client configuration (e.g. Claude Desktop claude_desktop_config.json):

{
  "mcpServers": {
    "nintendo": {
      "command": "uvx",
      "args": ["--from", "switch-parental-controls", "mcp"],
      "env": {
        "NINTENDO_SESSION_TOKEN": "your-token-here",
        "NINTENDO_TIMEZONE": "America/New_York",
        "NINTENDO_LANG": "en-US"
      }
    }
  }
}

Development

Requires mise:

# Install dependencies
mise run install

# Run tests
mise run test

# Run linter
mise run lint

# Fix lint issues
mise run lint-fix

# Open MCP Inspector (browser UI to test tools interactively)
mise run inspect

MCP Inspector

The inspect task launches the MCP Inspector — a browser-based UI for testing MCP tools interactively without needing a full AI client.

mise run inspect

This opens the inspector connected to the nintendo_mcp server. You can call any tool directly from the UI, which is useful for testing the authentication flow and verifying tool responses.

Testing with opencode locally

An example opencode config is provided at opencode.jsonc.example. To use it:

# 1. Copy the example config
cp opencode.jsonc.example opencode.jsonc

# 2. Optionally set NINTENDO_SESSION_TOKEN in opencode.jsonc

# 3. Open opencode in this project directory — it will pick up the local config
opencode

The local opencode.jsonc is gitignored so your session token stays private.

CI

Tests run automatically on pull requests via GitHub Actions. See .github/workflows/test.yml.
