Perplexity

Search chat history via indexed knowledge.

The `parse_whatsapp_chat` tool reads an exported WhatsApp file, structuring messages into JSON. Crucially, LlamaIndex takes this structured output and indexes it into a vector store. You stop reading linear threads; you start asking questions. You can query past chats semantically—like 'When did we talk about the Singapore trip?'—and get answers grounded in that indexed data.

Build RAG applications from chat logs.

You treat every parsed chat export as a document source for your knowledge base. The tool extracts message content, senders, and timestamps, which are then chunked and stored in the index. This capability means you can combine live API data with historical conversations. Your AI client pulls answers from both sources to give context-rich responses.

Extract metrics for conversation analysis.

The `parse_whatsapp_chat` tool doesn't just read text; it extracts participant statistics and message counts, turning raw chats into structured JSON. When LlamaIndex indexes this data, the search ability extends beyond mere content. You can ask questions like 'Who was the most active sender in Q3?' and get a definitive answer based on indexed metrics.

Setup guide

Set up WhatsApp Chat Export Parser 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 WhatsApp Chat Export Parser 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 WhatsApp Chat Export Parser tools.",
)
response = await agent.run("List recent WhatsApp Chat Export Parser data")

Common questions about WhatsApp Chat Export Parser MCP in LlamaIndex

Run `parse_whatsapp_chat` first to structure the chat data. Then, pass that structured JSON output to your FunctionAgent. The system indexes it, allowing you to ask natural language questions against years of conversation history.

Yes. Since the MCP tool output becomes a searchable knowledge base, your RAG application can index chat data alongside PDFs or internal memos, unifying all source material for powerful querying.

Beyond message content, the index stores senders, timestamps, and participant statistics. This depth means you can query not just *what* was said, but *when*, *by whom*, and *how many* people were involved.

You process each chat group's exported file using the tool. Each resulting structured JSON can then be added to your unified knowledge index, allowing you to query across multiple conversation contexts.

This server touches personal communication records: messages, senders, timestamps, and participant statistics. Always remember that indexing chat history involves highly sensitive personal information.
