How to Use the Parsio MCP in LlamaIndex

Q: Can LlamaIndex query Parsio templates dynamically?

Yes, your agent can call listmailboxtemplates to understand how incoming data is structured. It can then use gettemplatedetails to map those fields directly to your index metadata schema.

Q: How does LlamaIndex handle asynchronous Parsio extraction?

Your query pipeline can trigger extractdatafromfileasync for large documents. The agent polls getparseddocumentresult and updates the vector index only after the parsing job completes.

Index parsed document data directly into your LlamaIndex vector stores.

Semantic Search on Parsed Document Data

This Parsio MCP Server allows your LlamaIndex agent to extract clean, structured JSON from raw files before indexing. You run `extract_data_from_file_sync` to transform unstructured PDFs into clean key-value pairs, avoiding messy text chunks in your vector database. This makes your search results much more reliable. The agent reads the parsed fields and creates clean document nodes, allowing for precise metadata filtering during retrieval.

LlamaIndex Mailbox Indexing

Monitoring incoming document channels is straightforward when your LlamaIndex agent uses this Parsio MCP Server. The agent calls `list_mailboxes` to identify active document pipelines and uses `list_parsed_data_history` to fetch the latest parsed records. This prevents indexing duplicate data. The agent tracks the ingestion history and updates the vector index incrementally as new emails and PDFs arrive.

Context-Aware Parsing Queries

This Parsio MCP Server lets your LlamaIndex agent parse text snippets on the fly during a query pipeline. The agent uses `extract_data_from_text_sync` to process raw text blocks retrieved from external APIs before formatting them into the LLM context window. This eliminates the need for manual post-processing code. The agent gets clean data instantly, improving response speed and reducing token consumption.

Setup guide

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

Common questions about Parsio MCP in LlamaIndex

You use the MCP tool spec to pull data from your mailboxes. Call `list_parsed_data_history` to retrieve the structured JSON, then convert those records into LlamaIndex Document objects for indexing.

Yes, your agent can call `list_mailbox_templates` to understand how incoming data is structured. It can then use `get_template_details` to map those fields directly to your index metadata schema.

Your query pipeline can trigger `extract_data_from_file_async` for large documents. The agent polls `get_parsed_document_result` and updates the vector index only after the parsing job completes.

Yes, you can use the allowed tools filter in the MCP client. This restricts the agent to specific tools, like limiting it to `get_mailbox` and blocking administrative tools.

All data extraction happens via encrypted HTTPS connections directly to Parsio's API. The Vinkius runtime environment is stateless, ensuring that no document text or template metadata remains in memory after the tool execution finishes.
