# Sats4AI — Bitcoin-Powered AI Tools

Sats4AI is an MCP server that gives you access to 10+ AI tools, paid per use with Bitcoin Lightning. No API key, no signup — the Lightning payment is the only authentication.

## Setup

Add the Sats4AI MCP server to your `openclaw.json`:

```json
{
  "mcpServers": {
    "sats4ai": {
      "url": "https://sats4ai.com/api/mcp"
    }
  }
}
```

That's it. You now have access to all tools below.

## You Need a Lightning Wallet

To pay invoices, add a wallet MCP server alongside Sats4AI. The easiest options:

**Option A: Lightning Wallet MCP** (recommended)
```bash
npm install -g lightning-wallet-mcp
lw register --name "my-agent"   # save the API key
lw deposit 10000                # fund with any wallet
```

**Option B: Alby MCP Server**
```json
{
  "mcpServers": {
    "sats4ai": {
      "url": "https://sats4ai.com/api/mcp"
    },
    "wallet": {
      "command": "npx",
      "args": ["-y", "@getalby/mcp"],
      "env": {
        "NWC_CONNECTION_STRING": "nostr+walletconnect://YOUR_CONNECTION_STRING"
      }
    }
  }
}
```

Get your NWC connection string from [Alby Hub](https://getalby.com/ai).
