## What it does

This plugin brings SumUp payment workflows into Claude Code. It guides implementation of web checkouts using server SDKs and checkout widgets, along with remote reader interactions via the SumUp Cloud API.

It also covers mobile POS setups for iOS and Android card reader integrations. Live transactions will still require valid SumUp credentials and API keys.

# SumUp Skills

[![Documentation][docs-badge]](https://developer.sumup.com)
[![License](https://img.shields.io/github/license/sumup/sumup-go)](./LICENSE)

</div>

A collection of [Agent Skills](https://agentskills.io/home) for building SumUp payment integrations across card-present (terminal) and card-not-present (online) checkout flows.

## Installing

These skills work with agents that support the Agent Skills standard, including Claude Code, Cursor, Gemini CLI, OpenCode, OpenAI Codex, and Pi.

The packaged integrations include skills and hosted MCP configuration. Sign in with SumUp through your assistant to use account tools. Skills can be used without connecting an account. For the complete client setup guide, see [Plugins](https://developer.sumup.com/tools/llms/plugins/) and [MCP Server](https://developer.sumup.com/tools/llms/mcp-server/).

### Claude Code

Run in your terminal:

```bash
claude plugin marketplace add sumup/sumup-skills
claude plugin install sumup@sumup
claude plugin list
```

Inside Claude Code, you can also use `/plugin marketplace add sumup/sumup-skills` and `/plugin install sumup@sumup`. Follow the install summary's reload instructions, then open `/mcp` to authorize the SumUp server in your browser.

### Cursor

For teams, import `https://github.com/sumup/sumup-skills` from **Dashboard > Plugins & MCPs > Team Marketplaces > Add Marketplace > Import from Repo**, then add and install the SumUp plugin. See [Cursor plugins](https://cursor.com/docs/plugins).

For an individual setup, install the skills with `npx skills add https://github.com/sumup/sumup-skills` and configure the [hosted MCP connection](https://developer.sumup.com/tools/llms/mcp-server/).

### Gemini CLI

Install the extension from GitHub:

```bash
gemini extensions install https://github.com/sumup/sumup-skills --ref=main
gemini extensions list
```

Start a new Gemini CLI session and run `/mcp auth sumup` to authorize the hosted server.

### OpenAI Codex

Install using the Codex plugin marketplace:

```bash
codex plugin marketplace add sumup/sumup-skills
codex plugin add sumup@sumup
codex plugin list
```

Start a new Codex session to load the plugin and complete SumUp authorization when prompted. Plugins work in the Codex CLI and Codex in the ChatGPT desktop app. For the Codex IDE extension, install standalone skills and configure MCP directly.

To pull plugin updates, run `codex plugin marketplace upgrade sumup`, then start a new session.

### Kiro

Import this repository as a custom power from Kiro: **Powers > Add Custom Power > Import power from GitHub**.

Activate the power and authorize its SumUp MCP connection when prompted. For local testing, use **Import power from a folder** and select this repository root.

### Agent Skills Discovery

Agents and tools that support the [Agent Skills Discovery RFC](https://github.com/cloudflare/agent-skills-discovery-rfc) can discover the SumUp skills from:

`https://developer.sumup.com/.well-known/agent-skills/index.json`

Use this URL in clients that accept a discovery index or start from `https://developer.sumup.com` when the client discovers well-known skill indexes automatically.

### Clone / Copy

For a skills-only installation, clone this repo and copy the folders under `skills/` into the appropriate directory for your agent. This does not configure MCP:
