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 Claude Desktop discover MCP tools?
When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.
What happens if the MCP server is temporarily unavailable?
Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.
Can I connect multiple MCP servers simultaneously?
Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.
Is there a limit on the number of tools per server?
Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.
Does Claude Desktop support Streamable HTTP transport?
Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
