What is the Business Timezone & Holiday Scheduler MCP Server?
LLMs hallucinate dates. They forget leap years, daylight saving time rules, and have no idea when Easter or local bank holidays occur. This MCP makes your AI a perfect executive assistant by giving it real-time calendar and holiday intelligence.
Superpowers
- Business Day Calculation: Ask the AI for a 45-day SLA deadline. The MCP automatically skips weekends and fetches actual national public holidays (via the public Nager.Date API) for any country.
- Flawless Timezones: Instantly convert meeting times between complex IANA timezones (e.g., from
America/Sao_PaulotoAsia/Tokyo), accounting for real-world offset rules.
Built-in capabilities (2)
It automatically skips weekends. If you provide a countryCode (e.g. "US", "BR", "JP"), it will also query the Nager.Date API to skip national public holidays for that country. Calculates a future date by adding a specific number of business days (skipping weekends and optional public holidays)
Uses IANA timezone strings (e.g. "America/Sao_Paulo", "Asia/Tokyo"). Converts an exact date and time from one timezone to another

Frequently asked questions
Does this require an API key?
No. The timezone logic runs directly inside the Vinkius Edge process. For holiday lookups, it uses the free, public Nager.Date API without requiring authentication.
Why use this instead of letting the AI guess?
AIs do not have access to live calendars or global holiday databases. They will frequently schedule your deadlines on a Sunday or a major national holiday. This MCP enforces absolute temporal accuracy.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
