Perplexity

Build billing workflows using Cursor and the MCP Server

The `list_sequences` tool retrieves active invoice series such as FT 2026/ directly into your Cursor environment. This lets your agent generate code that targets the correct active billing sequence. Your agent reads this sequence data to configure automated invoicing scripts. This MCP Server setup avoids hardcoded series values and ensures your custom ERP integrations write to the correct active tax ledger.

Direct customer synchronization during development

The `list_clients` tool pulls registered Portuguese customer profiles directly into your Cursor chat. You can inspect customer IDs and tax details without switching to a web browser. When writing custom integration scripts, Cursor uses `get_client` to fetch full demographic records. This lets you debug data mapping issues using real payload data instead of fake JSON stubs.

Automated item creation with strict tax validation

The `list_items` tool displays all pre-configured billing items and services directly inside Cursor. This tool helps you verify that your local product IDs match the catalog on the Portuguese invoicing portal. If you need to add a new service, `get_item` retrieves specific item structures so your Cursor agent can replicate them. The editor validates your tax structures on the fly to prevent AT API errors.
