How to Use the Pennylane MCP in Cursor

Q: How do I add the Pennylane MCP server to my Cursor project configuration?

Create a .cursor/mcp.json file in your repository root and define the MCP server under the server list. Once saved, enable Agent mode in your editor chat to start querying your French accounting records immediately.

Q: Can my Cursor agent create new products in Pennylane during a coding session?

Yes, your agent can execute createproduct to add items to your catalog directly from the editor. It uses the exact schema defined in your active French accounting setup to prevent validation errors.

Q: How do I debug French VAT calculation issues in Cursor using Pennylane?

Ask your agent to run getcustomerinvoicedetails on a target invoice. The editor pulls the exact VAT breakdown from your live ledger, allowing you to trace calculation bugs in your code.

Q: Can I fetch supplier listings while writing integration scripts?

Absolutely. The editor calls listsuppliers to fetch your supplier directory, so you can map vendor IDs in your database to real records in your ledger.

Write financial code that queries live Pennylane ledger data directly inside your Cursor editor.

Inject live French financial schemas into Cursor

Stop guessing database schemas when building custom accounting integrations. This Pennylane MCP Server lets Cursor inspect your active French ledger via `list_categories` and `list_customers` so you can write code against real data formats. Your AI agent writes working functions by pulling live payloads with `get_customer_details`, eliminating the need for brittle mock files or outdated API documentation.

Automate invoice generation during development

Testing billing pipelines is faster when you work with actual records. Use your editor to run `create_customer` and `list_customer_invoices` to check how your application handles French tax rates under real-world conditions. By calling `get_customer_invoice_details` from the chat sidebar, you can inspect VAT calculations and line items instantly, letting you debug billing code without leaving your workspace.

Reconcile supplier records and estimates on the fly

Keep your purchasing systems in sync with your accounting platform. Your editor queries `list_supplier_invoices` and `get_supplier_details` to verify that your code maps vendor expenses to the correct categories. You can also pull up active quotes using `list_estimates` and verify their status via `get_estimate_details` to write automated reconciliation scripts that run flawlessly.
