Localized European Checkouts in Windsurf

Cascade reads your codebase, spots where your checkout is failing, and calls `list_payment_methods` to see what is actually available for your European buyers. It does not ask you for permission at every step. It just grabs the active methods and suggests the right integration logic. When a user hits buy, Cascade can test the actual transaction flow using `create_payment`. You get a real-time feedback loop inside Windsurf without jumping back and forth to the Mollie dashboard just to check if the payload works.

Automated Subscription Auditing

Stop writing custom scripts to hunt down active billing profiles. Let the Windsurf MCP Server configuration hook directly into your customer database, allowing Cascade to match local accounts with active plans via `list_customer_subscriptions`. If Cascade finds a mismatch, it pulls up the customer record using `list_customers` and flags the exact accounts that need manual billing updates. You get clean, automated subscription health checks directly inside your IDE.

Instant Refund Reconciliation

Customer support reports a missing refund, and you have to dig through logs. Cascade can run a multi-tool sequence starting with `list_refunds` for the specific transaction ID to see where the money went. It then chains that step to `get_payment_details` to verify the original payment status. This MCP integration lets you trace transaction failures and show the complete timeline directly in your Windsurf terminal panel.

Setup guide

Set up Mollie MCP in Windsurf

Prerequisites

Windsurf IDE installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the Mollie MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my Mollie payment history." If connected, Cascade will call the Mollie tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about Mollie MCP in Windsurf

Open your `~/.codeium/windsurf/mcp_config.json` file and add the server configuration under the `mcpServers` key. Alternatively, use the Settings menu, navigate to Cascade, and add it via the MCP Servers UI. Once you click refresh, Cascade will auto-discover all seven tools.

Yes, that is Cascade's main strength. You can tell it to verify a customer's status, and it will chain `list_customers` with `list_customer_subscriptions` to check their billing status in one go. You do not have to trigger each tool manually.

You should use your Mollie test API key during development. When Cascade invokes `create_payment` or `get_payment_details`, it interacts with the sandbox environment, keeping your live production transaction ledger clean and safe.

Windsurf captures the raw API error from the server and displays it directly in the Cascade chat. You can immediately ask the agent to rewrite your payload or fix the parameters based on the error details.

Vinkius runs the MCP server in an isolated V8 sandbox, meaning your Mollie API keys and customer transaction IDs never persist on any external disk. All payment data is processed ephemerally, keeping your European customer records compliant with local data privacy laws.
