SumUp MCP Server
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.
Getting started
npm install
npm run dev
Every MCP request must include a SumUp API key through the Authorization: Bearer <apiKey> header. We currently don't support other authentication methods. The worker listens on /mcp for the Streamable HTTP transport and /sse for the legacy SSE transport.
You can get your API key from the developer settings in the SumUp Dashboard.
Using from an MCP client
Any client that speaks the Streamable HTTP transport can connect to this server. For example, using mcp-remote:
{
"mcpServers": {
"sumup": {
"command": "npx",
"args": [
"mcp-remote",
"https://mcp.sumup.com/mcp",
"--headers",
"Authorization: Bearer <your-sumup-api-key>"
]
}
}
}
