NordStellar MCP

Connect any MCP-compatible AI assistant to NordStellar so you can query your platform data directly from chat.

What you get

Use natural language to ask about NordStellar data
No need to switch to the NordStellar UI or write GraphQL by hand
Secure login via your NordStellar account

Setup

1. Add to your MCP client

Add the NordStellar MCP server to your AI assistant’s MCP configuration (e.g. mcp.json or the equivalent in your client):

{
  "nordstellar": {
    "command": "uvx",
    "args": [
      "--from", "git+https://github.com/NordStellar/nordstellar-mcp",
      "nordstellar-remote-mcp-proxy",
      "https://platform-mcp.nordstellar.com/mcp"
    ]
  }
}

The default endpoint is https://platform-mcp.nordstellar.com/mcp. Contact your NordStellar administrator if you need a different URL.

2. First-time login

When you first use NordStellar, a browser window will open. Sign in with your NordStellar credentials. After that, you’re set—the connection stays authenticated until you sign out or the session expires.

3. Start using it

Ask your AI assistant things like “What projects do I have?” or “Show me recent activity” and it will use your NordStellar data to answer.

4. Install agent skills (optional)

You can install bundled skills the same way as other npx skills add workflows (for example the Google Workspace CLI repo):

# Install all skills at once
npx skills add https://github.com/NordStellar/nordstellar-mcp

# Or pick only what you need
npx skills add https://github.com/NordStellar/nordstellar-mcp/tree/main/skills/nordstellar-general
npx skills add https://github.com/NordStellar/nordstellar-mcp/tree/main/skills/attack-surface-management
npx skills add https://github.com/NordStellar/nordstellar-mcp/tree/main/skills/dark-web-search
npx skills add https://github.com/NordStellar/nordstellar-mcp/tree/main/skills/domain-squatting
npx skills add https://github.com/NordStellar/nordstellar-mcp/tree/main/skills/malware-infection-analysis

Credential storage

Session cookies are saved in your OS credential store under the service name NordStellar MCP:

macOS — Keychain
Windows — Credential Locker
Linux — Freedesktop Secret Service (for example GNOME Keyring or KWallet)

If no secure credential store is available, the proxy keeps credentials in memory only. In that mode, credentials are lost when the process exits.

Any application running as your user account may be able to read stored credentials through the OS credential APIs. This is the standard behavior for desktop credential stores.

Clear stored credentials

To remove stored session cookies, use one of the following:

Any platform: run nordstellar-remote-mcp-proxy --logout
macOS: run security delete-generic-password -s "NordStellar MCP"
Windows: remove the Generic Credential named NordStellar MCP from Credential Manager
Linux: remove the NordStellar MCP secret from your Secret Service keyring (for example with Seahorse or KWallet Manager)

Token lifetime and refresh behavior

This proxy stores whatever authentication cookies the NordStellar backend sets and refreshes the session through POST /auth/refresh-token when it needs a fresh AccessToken.

The repository does not define backend token lifetimes or refresh-token rotation policy. The AccessToken cookie payload includes an expires_in field, but the exact TTLs and whether refresh cookies rotate are backend-controlled and should be confirmed with NordStellar platform operators.

Requirements

uv installed (curl -LsSf https://astral.sh/uv/install.sh | sh)
Python 3.10 or newer (uv handles this automatically)
keyring — installed automatically as a dependency. Provides persistent, secure credential storage using each platform's native backend:
- macOS — Keychain
- Windows — Credential Locker
- Linux — Freedesktop Secret Service (GNOME Keyring / KWallet). Requires gnome-keyring or kwallet to be available; on headless systems, see the keyring docs for setup instructions.
