Automate Brazilian SLA steps in Mastra AI workflows

The `is_business_day` tool lets your Mastra AI workflows handle regional Brazilian calendars without breaking. Workflows often fail when they hit unexpected banking holidays. By integrating this check into your agent steps, you build conditional branches that wait out the weekend. Your workflows pause or route differently based on actual Brazilian banking operations. This protects your automated system from attempting to execute time-sensitive tasks on non-business days.

Handle Brazilian date-math retries and backoffs

Using `add_business_days` inside your Mastra AI agent allows you to schedule automated retries deterministically. If a payment or report fails on a holiday, you don't want to retry on a Sunday. This ensures your automated operations respect Brazilian national calendars without complex cron jobs. The framework handles the execution backoff, while the server provides the correct target dates. Your automation path remains clean, simple, and reliable.

One-command deploy with Mastra AI and MCP

Deploying this calendar MCP Server with Mastra AI offloads heavy date database logic to Vinkius. This setup gives your agent a lightweight API to query instead of bundling massive calendar libraries. You get instant access to accurate Brazilian dates with a clean deployment. You spread the client tools into your agent definition and deploy. The setup handles the transport layer automatically, ensuring your production agents always have access to the correct Brazilian holiday data.
