How to Use the Clearout.io MCP in LlamaIndex

Q: How do I search past validation jobs in LlamaIndex using Clearout.io?

You index the results of listbulkverificationjobs into your vector store. This allows your agent to answer semantic queries about when lists were cleaned and their overall health.

Q: Can LlamaIndex automatically verify new signups via Clearout.io?

Yes, you can configure a FunctionAgent with the verifyemailinstant tool. The agent verifies incoming emails and indexes the verification status on the fly.

Q: How does the Clearout.io MCP Server prevent hallucinations in LlamaIndex?

It provides hard deliverability metrics via checkbusinessemail and checkemailcatchall. Your agent relies on these real-time API responses instead of guessing email validity.

Q: How do I configure the MCP tools for my agent?

Install llama-index-tools-mcp and initialize the MCP client with our endpoint URL. Convert the client to tools using McpToolSpec and pass them to your agent.

Index live email verification data directly into your LlamaIndex vector store to ground your RAG applications in real lead quality metrics.

Ground your RAG apps with live validation data

The `verify_email_instant` tool inspects individual email addresses to supply your index with real-time deliverability data. Instead of relying on stale database exports, your agent queries this tool to inject fresh status details directly into your retrieval context. This live data becomes part of your vector index, allowing your system to answer queries based on actual, verified records. It prevents your agent from recommending dead or fake contacts during automated account reviews.

Build a queryable audit trail with this MCP Server

The `list_bulk_verification_jobs` tool retrieves your historical batch cleaning runs to build a searchable log of your database hygiene. Your LlamaIndex agent indexes these job summaries to let users ask natural language questions about past list audits. By checking `get_bulk_verification_status`, your agent can also monitor active jobs and update the index dynamically. You end up with a self-updating knowledge base of your entire email list health.

Filter out junk domains before indexing leads

The `check_email_catchall` tool identifies domains that accept all incoming mail, helping you flag potential deliverability risks. Your pipeline runs this check alongside `check_disposable_email` to filter out temporary inboxes before they ever touch your vector store. By keeping bad data out of your index, you save on token costs and storage space. Your agent only indexes high-quality, verified business domains checked via `check_business_email`.

Setup guide

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