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:
{
"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)
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
{
"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.
