Fewsats

Fewsats gives AI agents the ability to actually pay for things, exposing wallet balance, stored payment methods and offer payment over MCP using the L402 protocol — the HTTP 402 Payment Required scheme revived for machine-to-machine transactions. It is one of the few servers addressing agent commerce rather than agent retrieval, which makes it worth understanding even if you are not ready to let software spend money. Installed via pip or uvx with a Fewsats API key.
