Show HN: A free ACP payments module that adds Stripe payments to MCP tools
A free ACP payments module has been released that integrates Stripe payment processing into MCP (Model Context Protocol) tools, enabling developers to add payment capabilities to their AI-powered applications.
Background
- **MCP (Model Context Protocol)** is an open standard created by Anthropic that lets AI assistants (like Claude) interact with external tools and data sources — think of it as a "USB-C port" for AI, giving LLMs the ability to perform actions or fetch live data rather than just generating text.
- **ACP (AI Commerce Protocol)** is a new proposed standard built on top of MCP, designed specifically to let AI agents handle e-commerce tasks — browsing products, managing carts, processing payments.
- **Stripe** is a major online payment processor; this module connects Stripe's payment abilities to ACP-compatible AI tools, so an AI assistant could theoretically take payment for a product or service directly.
- This matters because it moves AI from "chatbot that suggests" toward "agent that transacts" — enabling AI systems to accept real payments, which is a critical step for autonomous AI commerce agents.
