How to Use the IP2WHOIS MCP in LlamaIndex

Q: How are registrant contacts handled by IP2WHOIS in LlamaIndex?

The getdomaincontacts tool returns the raw data. You decide what to index, allowing you to exclude sensitive PII from your searchable knowledge base.

Q: Does LlamaIndex support tool filtering for IP2WHOIS?

You can use the allowedtools filter to restrict which IP2WHOIS functions your LlamaIndex agent can access. This keeps your index clean and focused.

Index live domain registration data into LlamaIndex to ground your RAG applications in verifiable facts.

Build a searchable index with LlamaIndex

Feed the output of `lookup_domain_whois` directly into your LlamaIndex vector store. You create a persistent knowledge base of domain ownership that your agent can query anytime. Stop relying on stale training data. Your application accesses the live state of the registry whenever it needs to verify a domain's identity.

Ground AI responses using LlamaIndex and MCP

When your agent needs to justify a security decision, it calls `get_registrar_info` to retrieve authoritative data. This data is indexed, providing a clear citation for the agent's conclusions. You eliminate hallucinations by forcing the agent to look up the source of truth. The resulting answers are grounded in real-time records.

Monitor domain changes via LlamaIndex

Run periodic checks using `check_domain_expiry` and store the results in your index. You can then ask your agent to report on domains that require immediate renewal. This turns a static monitoring task into a dynamic conversation with your knowledge base. Your agent keeps track of the schedule for you.

Setup guide

Set up IP2WHOIS 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 IP2WHOIS 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 IP2WHOIS tools.",
)
response = await agent.run("List recent IP2WHOIS data")

Common questions about IP2WHOIS MCP in LlamaIndex

Initialize the MCP client in your script and pass the tool spec to your agent. The results are then ready to be ingested into your vector index.

Once you index the tool output, yes. Your agent can search through previous API responses stored in your vector store to find patterns.

The data resides in your local vector store. The server only handles the bridge between the API and your LlamaIndex application.

The `get_domain_contacts` tool returns the raw data. You decide what to index, allowing you to exclude sensitive PII from your searchable knowledge base.

You can use the allowed_tools filter to restrict which IP2WHOIS functions your LlamaIndex agent can access. This keeps your index clean and focused.
