How to Use the DVLA Vehicle API MCP in LlamaIndex

Q: How do I connect the DVLA Vehicle API to LlamaIndex?

Use the llama-index-tools-mcp package to initialize the MCP client. Convert the client to tools using McpToolSpec and pass them to your FunctionAgent to start running live UK registration lookups.

Q: Can LlamaIndex search through past DVLA Vehicle API queries?

Yes, LlamaIndex indexes the outputs of tools like getvehicledetails into a vector store. This allows your agent to perform semantic searches over previously retrieved vehicle records without hitting the live API again.

Q: How does LlamaIndex handle MOT status updates from this MCP Server?

The FunctionAgent calls getvehiclemotstatus to fetch the latest expiration date. It then updates your local index, ensuring your RAG application always references the most recent compliance data.

Q: How do I limit LlamaIndex to only check vehicle emissions?

Yes, use the allowedtools list to only expose getvehicleenvironmentaldata. This prevents the agent from calling other endpoints like tax status when you only need CO2 metrics.

Q: Is my DVLA Vehicle API data private when queried through LlamaIndex?

Your data is safe. LlamaIndex queries sent to getvehicletaxstatus run through an ephemeral MCP Server V8 sandbox on Vinkius, meaning your fleet's UK registration records are never cached or stored on our servers.

Index live DVLA registry data directly into LlamaIndex vector stores to stop vehicle compliance hallucinations cold.

Index Live DVLA Vehicle API Data for RAG

LlamaIndex goes beyond simple tool execution by ingesting outputs from `get_vehicle_details` directly into your semantic index. When your agent calls the tool, the returned UK registration data is indexed on the fly, making it searchable for future compliance queries. This prevents your LLM from hallucinating vehicle specifications. Instead of guessing, the agent queries the index for cached results of `get_vehicle_specifications` to answer complex fleet questions instantly.

Grounded Fleet Queries with MCP Server Tools

Keep your data-retrieval pipelines accurate by grounding every query in real-time government records using `get_vehicle_tax_status`. By exposing the tool to your LlamaIndex `FunctionAgent`, the engine verifies tax due dates before answering compliance questions. The framework uses the tool output to construct a verified context window. If a user asks which vans are unroadworthy, LlamaIndex pulls the exact expiration dates from `get_vehicle_mot_status` to deliver a factual report.

Intelligent Resource Filtering

LlamaIndex restricts which tools the agent accesses by applying filters to `get_vehicle_environmental_data` and other endpoints. Configure a restricted compliance agent that only has access to emissions data and `check_api_status`. This ensures that sensitive operational tools are locked down while still allowing environmental analysts to query emissions data. The agent remains lightweight because it only loads the specific schemas it needs to execute.

Setup guide

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