## What it does

SumUp MCP Server connects an MCP client with SumUp services. An agent can inspect merchant account data, payments, customers, and payouts through natural-language requests. The hosted service runs as a Cloudflare Worker.

The main endpoint is `https://mcp.sumup.com/mcp`, using Streamable HTTP; `/sse` supports the legacy SSE transport. A Durable Object keeps MCP session state across requests. Access uses OAuth: the client obtains a JWT access token and sends it as a Bearer token to `/mcp`.

SumUp keys such as `sup_sk_...` cannot authenticate against the hosted server. After adding the connection, open `/mcp` in Claude Code and finish the SumUp sign-in flow.
