Autonomous Card Lifecycle Management

The `update_card_status` tool changes Highnote card states to ACTIVE, FROZEN, or CLOSED. You tell Cascade to freeze a compromised card, and this MCP integration finds the card ID, checks the current status, and executes the block without requiring you to write custom API scripts. Cascade uses `list_payment_cards` to track physical and virtual Highnote cards in your program. Because Windsurf chains operations, it matches user records with active cards to pinpoint the exact card that needs a status update.

Ledger Reconciliation via Windsurf MCP Server

By calling `list_ledger_entries`, you pull individual Highnote ledger records to verify financial account balances. Cascade reads these entries to run automated reconciliations directly in your Windsurf workspace, matching internal databases with Highnote's source of truth. You feed a raw CSV of internal transactions to Windsurf, and Cascade calls `get_financial_account` to verify the Highnote balances. The agent detects discrepancies between your local code and the Highnote ledger instantly.

Instant Account Holder Lookup

Running the `list_account_holders` tool retrieves unique identifiers for individuals or businesses registered in your Highnote program. Cascade uses these IDs to map incoming support requests to actual financial profiles in your Windsurf workspace. When you need to inspect a specific user's spending, Windsurf combines this with `list_financial_transactions` to display recent Highnote transaction histories. Cascade formats the output as clean Markdown tables right inside your chat panel.

Common questions about Highnote MCP in Windsurf

Cascade reads your Windsurf workspace context and calls Highnote tools like `list_card_products` to pull available programs. It chains these calls to build files or debug issuance flows without manual API calls.

You manage existing card states via `update_card_status` and view issued Highnote cards using `list_payment_cards` in Windsurf. Cascade automates these updates by writing the execution scripts directly in your editor.

Open your `~/.codeium/windsurf/mcp_config.json` file and add the Highnote server configuration under the `mcpServers` key. Once saved, click Refresh in your Windsurf MCP panel to let Cascade discover the tools.

Cascade catches the Highnote API error, inspects your Windsurf connection parameters, and runs `get_api_profile` to verify your authentication. This helps you debug Highnote API key permissions immediately without leaving the editor.

Your Highnote transaction metadata and ledger entries stay within the secure V8 Isolate Sandbox in Windsurf. Vinkius handles the underlying endpoint authentication, meaning Windsurf never exposes your raw Highnote API keys to external LLMs over this MCP connection.
