Common questions

Is SumUp MCP Server safe?

It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 4 days ago, and the latest version (0.1.2) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

SumUp MCP Server

[](https://developer.sumup.com)

SumUp's Model Context Protocol (MCP) server for interactions between large language models (LLMs) and SumUp APIs. The MCP server allows you to connect to SumUp's services from an MCP client (e.g. Cursor, Claude) and use natural language to work with your SumUp account.

This package runs as a Cloudflare Worker and serves the MCP transport for SumUp.

Authentication follows the MCP OAuth resource-server flow:

The worker publishes protected resource metadata that points clients to the SumUp authorization server.
Clients send Authorization: Bearer to /mcp.
Bearer tokens must be JWT access tokens issued by SUMUP_AUTH_HOST and valid for the worker resource URL.

SumUp API keys such as sup_sk_... are not valid Bearer tokens for the hosted server.

The worker exposes /mcp for Streamable HTTP and /sse for the legacy SSE transport. Both routes are pinned to a Durable Object so MCP session state survives across requests within the same Worker deployment.

Using from an MCP client

Connect an OAuth-capable Streamable HTTP client to https://mcp.sumup.com/mcp and sign in with SumUp in your browser. The client discovers the authorization server from the protected resource metadata.

Install skills and MCP together

The SumUp plugin includes integration skills and hosted MCP configuration. For Codex:

codex plugin marketplace add sumup/sumup-skills

codex plugin add sumup@sumup codex plugin list

Start a new session and complete authorization when prompted. For other assistants, see the plugin setup guide.

Connect directly

If you only need MCP tools, configure the hosted server directly. For Codex:

codex mcp add sumup --url https://mcp.sumup.com/mcp

codex mcp login sumup codex mcp list

For Claude Code:

claude mcp add --transport http --scope user sumup https://mcp.sumup.com/mcp

claude mcp list

Open /mcp in Claude Code to authenticate. For Cursor, merge this entry into ~/.cursor/mcp.json:

"mcpServers": { "sumup": { "url": "https://mcp.sumup.com/mcp" } } }

Complete authorization in Cursor's MCP settings. If you installed the SumUp plugin, use its bundled connection instead of adding a duplicate manual entry.

After connecting, try a read-only prompt: "Use the SumUp MCP tools to show my merchant profile."

See the MCP setup guide for Gemini CLI, VS Code, Claude Desktop, and troubleshooting. For stdio clients and API-key workflows, use the local MCP CLI, which requires Node.js 22 or later.
