Manage Cards Directly in Claude Desktop

Connect your Highnote account to Claude Desktop and manage card statuses without opening another dashboard. Tell your agent to run `list_payment_cards` to see all virtual and physical cards issued in your program. If a user loses a card, tell Claude to freeze it. The agent executes `update_card_status` to push the status to FROZEN or CLOSED immediately. You can also pull specific card metadata using `get_payment_card_details` to check expiration dates and spending limits right in the chat interface.

Query Ledger Entries and Transactions

Stop pulling CSVs for reconciliation. Claude uses `list_ledger_entries` to pull individual ledger records for any financial account. You ask for the recent activity, and the agent fetches the raw data. When you need more context on a specific charge, Claude calls `get_transaction_details` to grab the metadata. You can also list recent spending across the board with `list_financial_transactions`, giving you a clear view of money movement.

Search Account Holders Fast

Finding the right customer ID usually means clicking through multiple screens. Now you just ask your AI client to run `list_account_holders` and grab the unique ID for a person or business. Once you have that ID, you can check their balances via `list_financial_accounts` or drill into a specific balance with `get_financial_account`. The MCP Server handles the API routing while you just type questions.

Common questions about Highnote MCP in Claude Desktop

Open your Claude Desktop settings and click Edit Config. Add the Highnote server details to your claude_desktop_config.json file and restart the app. You can also paste the remote URL into Claude Web under Integrations.

Yes. The integration includes write access for card states. Claude uses the update_card_status tool to change a card to ACTIVE, FROZEN, or CLOSED based on your prompt.

You ask Claude to check the ledger for a specific timeframe. The agent calls list_ledger_entries and formats the output into a table or summary right in your chat window.

You can manage any program configured in your account. Run list_card_products to see available setups like Consumer or Fleet cards.

The server processes sensitive ledger entries and card metadata in memory. Vinkius runs this connection inside a V8 Isolate Sandbox that destroys itself after the request finishes, leaving no cached transaction histories behind.
