How to Use the Nestoria MCP in LlamaIndex

Q: Can LlamaIndex cache property data retrieved from Nestoria?

Yes. You can index the outputs of the searchlistings tool into a local vector store. LlamaIndex queries this local index first before hitting the Nestoria MCP Server for new data.

Q: Can I combine Nestoria listings with local PDF documents in LlamaIndex?

Yes. You can merge the live data from the Nestoria searchlistings tool with local files in a unified query engine. LlamaIndex synthesizes answers using both sources.

Index Nestoria listings into your LlamaIndex vector store for hallucination-free property RAG applications.

Build real estate RAG with LlamaIndex and this MCP Server

The `search_listings` tool extracts real-time property data from Nestoria and feeds it directly into your LlamaIndex data pipelines. Instead of relying on static real estate files, your LlamaIndex agent pulls active Nestoria listings and converts them into document nodes on the fly. This active Nestoria data feed ensures your LlamaIndex query engine answers questions using current market rates instead of outdated training weights. You avoid hallucinated rental prices because every LlamaIndex response is grounded in the raw JSON returned from the Nestoria API.

Vectorize and search Nestoria property listings

The `search_listings` tool outputs structured property details that LlamaIndex instantly indexes into your vector store. Your system runs semantic searches across these retrieved Nestoria listings to match abstract user preferences with actual market availability. You configure the LlamaIndex MCP tool spec to retrieve these listings asynchronously, keeping your index updates fast. This pipeline lets users search for complex criteria like quiet neighborhoods near public transit against raw Nestoria data.

Ground agent responses in real property metrics

The `search_listings` tool provides the empirical foundation your LlamaIndex FunctionAgent needs to verify market trends. The agent calls the tool to pull current pricing for a specific postal code, then uses that data to run local market comparisons. This process eliminates the guesswork from automated property valuations. Your agent references verified Nestoria listings in its final output, citing specific properties and prices to prove its conclusions.

Setup guide

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