Use cases

• Enable an LLM to send micropayments for API calls or services
• Check wallet balance or transaction history via natural language
• Automate Lightning tipping or pay-per-request workflows in agents

Pros

• Direct integration between MCP agents and real Bitcoin payments
• Small codebase (TypeScript) easy to audit or extend
• Leverages open, decentralized Nostr protocol for wallet control

Cons

• Requires an Alby or compatible Lightning wallet already set up
• Very early stage with only 14 stars and limited community support
• Dependent on Nostr infrastructure which adds latency and complexity
