Koru Shield MCP Server

Manage your Koru Shield DNS protection through AI assistants. Block domains, check policies, review blocked queries, manage schedules, and more, all through natural language.

What it does

Exposes your Koru Shield account as Model Context Protocol tools:

Tool	What it does
list_profiles / get_profile	List and inspect DNS protection profiles
create_rule / list_rules / delete_rule	Block or allow domains per profile
list_filter_categories / set_filter_category	Toggle categories (adult, gambling, social media...)
simulate_policy	Check if a domain would be blocked right now
get_logs	Recent DNS queries: allowed, blocked, when
analytics_summary	Totals, blocked percentage, encrypted queries
list_schedules / create_schedule / delete_schedule	Time windows (bedtime, homework hours)
list_devices	Devices enrolled per profile
get_entitlements	Plan, limits, current usage
get_referral_code	Your referral link

Example prompts once connected:

• "Block tiktok.com on the Kids profile"
• "Would youtube.com be blocked on Kids right now?"
• "Show me what got blocked today"
• "Turn on adult content filtering for the whole house"
• "Add a bedtime schedule 9pm to 7am on weekdays for the Kids profile"

Setup

1. Get a Koru Shield API key

Sign in at https://my.korushield.com, go to API keys, and create one. Copy the key.

2. Install

No install needed. Run directly with npx:

npx -y korushield-mcp-server

Set your key as an environment variable:

export KORU_SHIELD_API_KEY="your-key-here"

Optional: KORU_SHIELD_API_URL overrides the API base URL (default https://my.korushield.com/api).

3. Connect your AI client

Claude Code

claude mcp add koru-shield -- npx -y korushield-mcp-server

(Claude Code passes environment through, so export KORU_SHIELD_API_KEY first. Or use the HTTP transport below with a header.)

Cursor / VS Code

Add to your MCP config (~/.cursor/mcp.json or VS Code mcp.json):

{
  "mcpServers": {
    "koru-shield": {
      "command": "npx",
      "args": ["-y", "korushield-mcp-server"],
      "env": {
        "KORU_SHIELD_API_KEY": "your-key-here"
      }
    }
  }
}

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "koru-shield": {
      "command": "npx",
      "args": ["-y", "korushield-mcp-server"],
      "env": {
        "KORU_SHIELD_API_KEY": "your-key-here"
      }
    }
  }
}

HTTP transport (remote)

For clients that connect over HTTP (agents, hosted setups):

MCP_TRANSPORT=http PORT=3000 KORU_SHIELD_API_KEY="your-key-here" npx -y korushield-mcp-server

Or pass the key per-request instead of the env var:

POST https://your-host/mcp
Authorization: Bearer <koru-shield-api-key>

Health check: GET /healthz.

Security notes

• Your API key grants full control of your Koru Shield account, including deleting rules and schedules. Treat it like a password.
• Prefer a dedicated API key for AI assistants so you can revoke it independently.
• The server never logs or transmits your key anywhere except to the Koru Shield API.

Development

npm install
npm run build
npm start

Test with the MCP Inspector:

KORU_SHIELD_API_KEY="your-key-here" npm run inspector
