Perplexity

Semantic search with this MCP Server

LlamaIndex excels at retrieving unstructured text, but searching for precise temporal relationships usually breaks down. This MCP Server allows your agent to calculate exact age intervals using `calculate_exact_age` and index those structured metrics directly into your vector store. By converting the tool's raw chronological outputs into document metadata, your RAG pipeline can filter search results by exact age brackets. Your agent queries the index knowing the temporal data is mathematically sound.

Indexing milestones for proactive retrieval

Structuring future milestones as searchable nodes changes how your RAG application handles scheduling. The `calculate_time_until_milestone` tool generates precise countdown metrics that can be stored alongside user profile documents. When a user asks about upcoming events, the LlamaIndex query engine retrieves these calculated milestones instead of trying to compute them on the fly. This prevents the LLM from hallucinating dates during the retrieval phase.

Querying temporal comparisons

Building a system that evaluates historical gaps requires structured comparative data. The `compare_two_ages` tool provides the exact delta between two dates, which your indexer can store as a relative distance metric. Your query engine uses these pre-computed deltas to resolve complex user prompts about cohort differences. Combining LlamaIndex's retrieval capabilities with the deterministic calculations of `calculate_next_anniversary` via the MCP protocol ensures your temporal answers are always grounded.

Setup guide

Set up Absolute Chronological Timeline Engine 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 Absolute Chronological Timeline Engine 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 Absolute Chronological Timeline Engine tools.",
)
response = await agent.run("List recent Absolute Chronological Timeline Engine data")

Common questions about Absolute Chronological Timeline Engine MCP in LlamaIndex

You run the tool via the McpToolSpec client and feed the resulting structured age data into your Document metadata. This allows LlamaIndex to build a vector index that is aware of exact chronological metrics.

Yes, it completely offloads the calendar math from the LLM to a local, deterministic engine. Your LlamaIndex agent simply reads the output of `calculate_exact_age` instead of guessing the number of days between dates.

You can register the tools so the sub-question router calls `compare_two_ages` to resolve specific temporal sub-queries. The generated chronological data is then synthesized into the final response.

Instantiate the BasicMCPClient with your Vinkius endpoint URL and convert it using McpToolSpec. Pass the resulting tool list to your FunctionAgent to expose the chronological capabilities.

The server operates locally within a secure V8 sandbox, meaning your raw birthdate strings never leave the execution context to train external models. Only the final, calculated chronological metrics are indexed into your local vector store.
