Give Claude Code a Lightning Wallet

Get Claude Code paying Lightning invoices and accessing L402 APIs in under 3 minutes.

For the full MCP setup guide (all clients, all wallet options), see MCP Quickstart.

Step 1: Get a Strike API Key

Strike is the fastest way to get started — no infrastructure required.

Go to developer.strike.me and log in with your Strike account
Click Generate API Key and copy the key

Why Strike?

Strike requires zero infrastructure, supports L402 (returns preimage), and handles custody. Other options: NWC wallets (CoinOS, Alby Hub, CLINK) or LND (self-hosted).

Step 2: Install the MCP Server

# .NET (recommended)
dotnet tool install -g LightningEnable.Mcp

# Or Python
pip install lightning-enable-mcp

Step 3: Configure Claude Code

Edit ~/.claude/claude_desktop_config.json (macOS/Linux) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

.NET:

{
  "mcpServers": {
    "lightning-enable": {
      "command": "dotnet",
      "args": ["tool", "run", "lightning-enable-mcp"],
      "env": {
        "STRIKE_API_KEY": "your-strike-api-key"
      }
    }
  }
}

Python:

{
  "mcpServers": {
    "lightning-enable": {
      "command": "uvx",
      "args": ["lightning-enable-mcp"],
      "env": {
        "STRIKE_API_KEY": "your-strike-api-key"
      }
    }
  }
}

Restart Claude Code after saving.

Step 4: Test It

Check my Lightning balance

Claude will call check_wallet_balance and show your Strike balance. Try also:

Pay this Lightning invoice: lnbc...
Fetch data from https://agent-commerce.store/api/weather/forecast?lat=40.71&lon=-74.00
Buy me a Lightning Enable t-shirt from store.lightningenable.com

Spending Limits

Create ~/.lightning-enable/config.json to protect yourself:

{
  "currency": "USD",
  "tiers": {
    "autoApprove": 0.10,
    "logAndApprove": 1.00,
    "formConfirm": 10.00
  },
  "limits": {
    "maxPerPayment": 50.00,
    "maxPerSession": 20.00
  }
}
