What is the Payrexx MCP Server?

Connect your Payrexx account to any AI agent and take full control of your payment orchestration and checkout flows through natural conversation. Payrexx is the leading payment provider in Switzerland and Europe, and this integration allows you to create payment gateways, monitor real-time transaction metadata, and manage recurring subscriptions directly from your chat interface.

What you can do

  • Gateway & Link Orchestration — Create custom payment gateways and multi-use payment links programmatically to ensure your sales flow is always synchronized.
  • Transaction Lifecycle Management — Access and monitor real-time transaction statuses and retrieve detailed financial metadata directly from the AI interface to track revenue health.
  • Subscription & Recurring Control — Manage recurring billing cycles and list active subscriptions via natural language to drive better customer retention.
  • Payout & Invoice Oversight — Access organizational payouts and list invoices to maintain a clear overview of your cash flow using simple AI commands.
  • Operational Monitoring — Track system responses and manage webhook metadata to ensure your automation workflows are always optimized.

How it works

1. Subscribe to this server
2. Enter your Payrexx Instance Name and API Secret from your merchant settings
3. Start managing your payment operations from Claude, Cursor, or any MCP-compatible client

No more manual status checks in the dashboard. Your AI acts as a dedicated payments coordinator or finance coordinator.

Who is this for?

  • Swiss & European Merchants — quickly retrieve payment summaries and monitor transaction status without switching apps.
  • Finance Operations Teams — automate the retrieval of payout metadata and track organizational billing via natural conversation.
  • Developers — integrate real-time payment data and gateway management directly within the chat.

FAQ

Frequently asked questions

01

Can my AI automatically find the status for a specific transaction by its ID?

Yes! Use the get_transaction tool with the Transaction ID. Your agent will respond with complete metadata, including payment method, currency, amount, and final status in seconds.

02

How do I find my Payrexx API Secret and Instance Name?

Log in to your Payrexx merchant dashboard, navigate to Settings > API, and you will find your unique secret key and instance name (e.g., yourname.payrexx.com) there.

03

Does this work for recurring payments?

Absolutely. You can use the list_subscriptions tool to monitor active recurring billing cycles and orchestrate multi-use gateways for recurring customer payments.

04

How does the OpenAI Agents SDK connect to MCP?

Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.

05

Can I use multiple MCP servers in one agent?

Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.

06

Does the SDK support streaming responses?

Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
