About 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.

LangChain's ecosystem of 500+ components combines seamlessly with BR Business Days Calculator through native MCP adapters. Connect 2 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.

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-scheduler that 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.

The BR Business Days Calculator MCP Server exposes 2 tools through the Vinkius. Connect it to LangChain in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
