Headless Client Ledger Management

The integration uses `list_customers` and `get_customer_details` to let you manage your client ledger directly from your Claude Code terminal. You can inspect specific accounts in Pennylane without leaving your shell. It is built for speed, allowing you to script entire Pennylane accounting checks from a single Claude Code terminal session.

Command-Line Reconciliation via MCP Server

This MCP Server exposes `list_customer_invoices` and `get_customer_invoice_details` to let you audit Pennylane billing data from the command line using Claude Code. When you need to drill down into a specific transaction, Claude Code calls the tool to dump the VAT rates and line items. It is the fastest way to debug Pennylane billing issues without opening a browser.

Terminal-Driven Supplier Audits

The server uses `list_suppliers` and `list_supplier_invoices` to manage your vendor expenses directly inside your Claude Code terminal. If you need to verify a vendor's details in Pennylane, the Claude Code agent runs `get_supplier_details` to fetch their tax info. You can automate these checks in your local shell scripts to monitor Pennylane expenses on a schedule.
