How to Use the Business Timezone & Holiday Scheduler MCP in LlamaIndex

Q: How does Business Timezone & Holiday Scheduler prevent hallucinations in LlamaIndex?

The LlamaIndex agent calls addbusinessdays to get real calendar facts from the Nager.Date API. This stops the LLM from guessing if a specific date is a holiday. The exact calculated date is then indexed into your vector store.

Q: Can I use Business Timezone & Holiday Scheduler with LlamaIndex FunctionAgent?

Yes, you load the MCP tools using McpToolSpec and pass them to the LlamaIndex FunctionAgent. The agent decides when to call converttimezone or addbusinessdays based on the query. This workflow requires zero manual scheduling code.

Q: How do I set up Business Timezone & Holiday Scheduler in LlamaIndex?

Run pip install llama-index-tools-mcp to get the necessary adapter. Initialize the client with the Vinkius MCP Server URL. Your LlamaIndex application can now access live calendar logic.

Index holiday schedules and timezone offsets directly into your LlamaIndex RAG pipeline.

Index holiday-aware dates into LlamaIndex

The `add_business_days` tool calculates future dates while ignoring weekends and national holidays. Your LlamaIndex agent uses this tool to find correct delivery dates and indexes the results. This turns dynamic API outputs into searchable data points. Your vector store gets updated with precise business dates instead of stale calendar estimates.

Ground LlamaIndex queries in correct timezones

The `convert_timezone` tool handles conversions between IANA zones to keep your indexed data aligned. Your agent queries this MCP tool to normalize all timestamps before saving them. This eliminates timezone mismatch issues during semantic searches. Your RAG pipeline retrieves documents matching the exact local time of the user.

Build calendar-aware RAG with this MCP Server

This MCP Server integrates with LlamaIndex using `llama-index-tools-mcp` to expose live scheduling data. Your agent can search past scheduled dates in your index and compare them with new calculations. This ensures your knowledge base stays synchronized with real-world business calendars.

Setup guide

Set up Business Timezone & Holiday Scheduler MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Business Timezone & Holiday Scheduler MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Business Timezone & Holiday Scheduler tools.",
)
response = await agent.run("List recent Business Timezone & Holiday Scheduler data")

No, the MCP Server operates independently using the Nager.Date API for global holidays and IANA databases for timezones. You do not need to link Google Calendar or Outlook to make calculations.

Only the specific date strings, country codes, and IANA timezone targets are processed by the server. Vinkius executes the code in a secure, ephemeral container that leaves no trace after the request completes. Your internal calendar schedules are never cached.
