Perplexity

Inject deterministic calendar math into Cursor

The `add_business_days` tool lets your agent calculate precise timelines in Brazil by adding or subtracting integers from a base date. It bypasses typical LLM math errors by using a hardcoded registry of Brazilian national holidays. While writing backend code in Cursor, your agent can call this tool to generate realistic seed data or verify database migration dates. You get working code grounded in actual Brazilian calendar rules instead of placeholder logic.

Validate transaction schedules directly in your editor

The `is_business_day` tool checks if a specific ISO date string is an active business day in Brazil. It instantly filters out Saturdays, Sundays, and national holidays. When you run tests or debug payment workflows inside Cursor, the editor queries this tool to verify date inputs. This prevents holiday-related processing errors before you commit your code.

Run the MCP Server inside your Cursor agent workflows

This MCP Server hooks directly into Cursor's agent mode, enabling the AI to invoke calendar tools while editing your files. The editor manages the connection using your local configuration file. Instead of hardcoding holiday arrays in your codebase, you let the editor fetch the correct date states dynamically. This keeps your local development environment clean and your code files lightweight.

Setup guide
