What is the BR Business Days Calculator MCP Server?
LLMs cannot reliably calculate SLAs or business delivery times. If you ask an AI to 'add 5 business days to Feb 10th', it will frequently ignore Carnival or count a Saturday. This MCP solves this by providing a static, local-first calculation engine that perfectly handles Brazilian national holidays and weekends.
The Superpowers
- Flawless SLA Math: Guarantee that your agents' promised delivery dates are exactly right, automatically skipping weekends and static/dynamic BR holidays.
- Zero Latency & 100% Local: Unlike our global
business-timezone-schedulerthat uses the Nager.Date API, this engine uses a hardcoded Brazilian holiday list in the V8 isolate. Zero external network calls. Instant execution. - Absolute Determinism: Eliminates the hallucination of non-existent business days, bringing enterprise reliability to AI agents.
Built-in capabilities (2)
Pass a starting date and the number of days to add (use negative values to subtract). The engine skips weekends and Brazilian holidays automatically. Adds or subtracts X Brazilian business days from a given date
Pass the date as an ISO string (YYYY-MM-DD). The engine accounts for all Brazilian national holidays and weekends. Checks if a given date is a Brazilian business day (excludes weekends and BR national holidays)
