Lobstercash

This gives Claude the ability to spend money on your behalf with guardrails. It's a CLI wrapper around a Solana wallet and virtual card system, designed for autonomous purchase flows. The interesting bit is that it handles both crypto payments (x402 protocol APIs, direct token sends) and regular online shopping with card checkout, either through built-in browser automation or by handing credentials to whatever browser tooling your IDE already has. Everything requires explicit approval URLs before funds move. The documentation is thorough about decision trees and error states, which matters when you're giving an AI access to money. Use it when you want an agent to actually complete transactions rather than just find products or generate purchase links.
