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)

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 Windsurf discover MCP tools?
Windsurf reads the mcp_config.json file on startup and connects to each configured server via Streamable HTTP. Tools are listed in the MCP panel and available to Cascade automatically.
Can Cascade chain multiple MCP tool calls?
Yes. Cascade is an agentic system. it can plan and execute multi-step workflows, calling several tools in sequence to accomplish complex tasks without manual prompting between steps.
Does Windsurf support multiple MCP servers?
Yes. Add as many servers as needed in mcp_config.json. Each server's tools appear in the MCP panel and Cascade can use tools from different servers in a single flow.
