Alby MCP

Alby MCP turns Claude into a Lightning wallet operator. You give it a Nostr Wallet Connect connection string, and it can send sats, generate invoices, and check balances without you touching a browser or mobile app. The setup is straightforward if you already use Alby or another NWC-compatible wallet. You paste the connection string into an environment variable, restart Claude Desktop, and you're live. I've used it to tip contributors in a GitHub issue thread by asking Claude to send 1,000 sats to a Lightning address. It worked first time, returned a preimage, and the payment settled in under two seconds. The real win is micropayments in agent workflows. If you're building a content moderation bot that pays human reviewers per decision, or a research assistant that buys paywalled articles on demand, this is the missing piece. It's also useful for invoicing. You can ask Claude to generate a 5,000-sat invoice with a memo, and it hands you a BOLT11 string you can share or embed. The quirks are mostly around error handling. If your wallet balance is too low, Claude sometimes retries instead of failing cleanly. The connection string is sensitive, so treat it like an API key. Don't commit it to a repo or share logs. The package is maintained by Alby, so updates track their wallet API changes. If you're not in the Lightning ecosystem, this won't make sense to you. But if you already run a node or use Alby for zaps, it's a natural extension. The use cases are niche but high-value. I'd reach for this when building agent-to-agent payment rails or automating creator economy workflows. It's not for bulk transactions or complex routing, but for instant, low-friction payments in the sub-dollar range, it's the best option in the MCP ecosystem.
