sumup-skills is a collection of Agent Skills for building SumUp payment integrations, covering both terminal (card-present) and online (card-not-present) checkout flows, according to the GitHub README. The README lists six skills covering end-to-end checkout implementation, choosing an integration path, API/SDK upgrades, debugging common failures, MCP server configuration, and sandbox testing setup. These skills can be installed into agents such as Claude Code, Cursor, Gemini CLI, OpenCode, OpenAI Codex, and Pi, per the README's installation instructions. Separately, the SumUp homepage indicates the company operates across Europe, North and South America, and Oceania, but does not provide technical integration details. No pricing or additional feature information is given in the provided sources, so those aspects are unknown.
