fewsats-mcp is an MCP server that integrates with Fewsats to enable AI agents to purchase items in a secure manner. It exposes a compact set of tools for wallet and payment management: balance to retrieve the user's wallet balance; payment_methods to retrieve available methods; pay_offer to execute an offer by providing an offer_id and an l402_offer object containing offers (each with id, amount, currency, description, title), a payment_context_token, a payment_request_url, and a version; and payment_info to fetch detailed information for a given pid. The server is designed for easy integration and can be run with uvx (recommended) or installed via pip and executed as a script. Configuration supports environment-based API keys, demonstrated by an example claude_desktop_config.json configuration using FEWSATS_API_KEY. The MCP server provides secure flows for AI agents to select offers, initiate payments, and retrieve status or details, enabling automated purchasing while keeping payment data structured and traceable.
