The Stripe Agent Toolkit provides a Python and TypeScript library designed to integrate Stripe API functionality into agentic workflows. Supporting popular agent frameworks like OpenAI's Agent SDK, LangChain, CrewAI, Vercel's AI SDK, and Model Context Protocol (MCP), the toolkit allows developers to easily incorporate Stripe's capabilities into their intelligent agents. Built directly on the Stripe Python and Node SDKs, it offers function calling integration, context management for connected accounts, and middleware for metered billing with Vercel's AI SDK. The toolkit supports a wide range of Stripe API methods, including customer, product, price, payment link, invoice, and refund management.
