Index live age data into LlamaIndex

The `calculate_current_age` tool outputs structured chronological data that your agent indexes directly into your vector store. This prevents hallucinations when querying user profiles or temporal statistics. LlamaIndex treats these outputs as live documents. Your RAG pipeline can retrieve these exact age metrics to ground its answers in real-time facts.

Semantic search for historical birth days

You can use the `identify_birth_weekday` tool to attach specific historical context to user records. The agent resolves dates to weekdays and indexes the result for semantic querying. This MCP ensures your knowledge base stays updated with accurate temporal metadata. You can search your index for users born on specific days of the week without manual database queries.

Ground your RAG pipeline with birthday timelines

The `get_upcoming_birthday_info` tool provides the exact countdown to the next milestone. Your agent indexes this countdown data to answer questions about upcoming events dynamically. LlamaIndex combines this live data with your existing static documents. This creates a unified, queryable index that always has access to current temporal facts.

Setup guide

Set up Age Calculator 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 Age Calculator 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 Age Calculator tools.",
)
response = await agent.run("List recent Age Calculator data")
