How to Use the Kelley Blue Book Valuation MCP in LlamaIndex

Q: What happens when I run a Kelley Blue Book Valuation query through LlamaIndex?

Your agent calls the tool, like getmarkettrends, through the MCP server. LlamaIndex then takes the returned data—in this case, pricing shifts—and embeds it into your configured vector store. Now that trend data is part of your agent's knowledge.

Index live Kelley Blue Book data into a searchable knowledge base with LlamaIndex for advanced RAG.

Turn KBB Data into a Queryable Index with LlamaIndex

Connect the KBB tools and start indexing. When your agent calls `get_vehicle_valuation` or `get_vehicle_details`, LlamaIndex doesn't just return the answer—it adds that data to a vector index. Now your application has a memory of every car you've ever looked up. This means you can ask follow-up questions later. For instance, query your index for "all sedans valued last month" or "compare the trade-in values for the two Honda Civics we checked." The answers come from your private, indexed KBB data, not by re-running API calls.

Augment Queries with Real-Time Valuations

This is how you ground your agent in facts. When a user asks a question, your LlamaIndex agent can decide whether to query its existing index of past KBB lookups or fetch fresh data using a tool like `get_market_trends`. It's a true RAG setup where the agent retrieves existing data and augments it with live API calls. This MCP server gives your agent the tools to validate its knowledge. If the index contains a valuation from six months ago, the agent can use `get_vehicle_valuation` to get a new price, compare the two, and report on the depreciation.

Drill Down from Make and Model to Trim

Your agent can navigate the KBB database intelligently. It can start with a broad search using `list_makes_by_year`, let the user pick one, then use `list_models_by_make` to show the available models. From there, it can fetch all styles with `list_trim_styles`. Each step can be indexed. By the time you've gotten a valuation, your knowledge base contains the entire path taken to get there. This creates a rich, structured dataset of vehicle information your agent can reference in future queries.

Setup guide

Set up Kelley Blue Book Valuation 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 Kelley Blue Book Valuation 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 Kelley Blue Book Valuation tools.",
)
response = await agent.run("List recent Kelley Blue Book Valuation data")

Common questions about Kelley Blue Book Valuation MCP in LlamaIndex

LlamaIndex turns the output of the KBB tools into a searchable knowledge base. Instead of just getting a one-time answer from `get_vehicle_valuation`, the result is indexed, allowing your agent to query and compare past valuations.

Yes. You can combine documents, like vehicle condition reports, with live API data from tools like `get_vehicle_by_vin`. Your LlamaIndex agent can then answer questions using both the static documents and fresh data from the Kelley Blue Book Valuation MCP server.

Your agent calls the tool, like `get_market_trends`, through the MCP server. LlamaIndex then takes the returned data—in this case, pricing shifts—and embeds it into your configured vector store. Now that trend data is part of your agent's knowledge.

No, this MCP server provides live access to Kelley Blue Book data. LlamaIndex is what you use to create your own private, indexed copy of the data you retrieve. The server itself holds no data.

The MCP server itself is stateless; it just processes tool calls. Any vehicle data you retrieve, like valuations or VIN details, is managed by your LlamaIndex application and stored in the vector database you control. Vinkius doesn't see or store the results of your KBB queries.
