Indexing Contact Data for RAG

The `parse_vcard_contacts` tool converts raw `.vcf` files into structured JSON, which you can then index. This means your LlamaIndex doesn't just process the data; it makes it searchable knowledge. You can build Retrieval Augmented Generation (RAG) apps that pull specific contact details out of massive archives and ground them in actual API results.

Searching Contacts Across Multiple Sessions

LlamaIndex lets you query past sessions. By indexing the JSON output from `parse_vcard_contacts`, your knowledge base remembers contacts from previous runs. You can ask, 'What was Jane Doe's job title last quarter?' and get an answer based on indexed data. It stops hallucinations because every search pulls from confirmed contact records.

Consolidating Contact Information

If you have multiple vCard exports, `parse_vcard_contacts` processes them all into clean JSON. This unified data set is perfect for indexing in LlamaIndex. You build one comprehensive, queryable index from many disparate sources. The structured output ensures that names and phone numbers are always mapped correctly before they hit your vector store.

Setup guide

Set up vCard Contacts Parser Extended 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 vCard Contacts Parser Extended 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 vCard Contacts Parser Extended tools.",
)
response = await agent.run("List recent vCard Contacts Parser Extended data")

Common questions about vCard Contacts Parser Extended MCP in LlamaIndex

It provides the necessary structured JSON data that can be ingested into a vector store. This allows your LlamaIndex agent to answer questions about contacts using factual, retrievable information.

Yes. Since the tool extracts names, emails, and organization details into JSON, you can create highly specific indexes that answer questions like 'Find all contacts at Company X who have called recently.'

It handles standard contact information: names, phone numbers, emails, and organization details. This structured JSON is what gets indexed into the knowledge base.

The tool processes one file at a time by requiring an absolute path. You feed it the file, get structured JSON, and then run that JSON through your LlamaIndex indexing pipeline.

This server touches personal contact details (names, emails, phone numbers). Ensure the indexed knowledge base is secured and access is restricted to prevent unauthorized viewing of sensitive contact information.
