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)
Why Pydantic AI?

Frequently asked questions
Does it require an external API?
No! It uses a statically compiled list of Brazilian national holidays.
Does it skip weekends automatically?
Yes, Saturdays and Sundays are ignored.
Are Carnival and Easter supported?
Yes, the dynamic dates for these holidays are embedded.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your BR Business Days Calculator MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
