How to Use the Megaventory MCP in LlamaIndex

Q: How do I connect Megaventory to my LlamaIndex RAG pipeline?

Install llama-index-tools-mcp and initialize the basic client with your Vinkius endpoint. Convert the connection into a tool spec using McpToolSpec to expose the 14 ERP tools to your index agents.

Q: Can LlamaIndex search through Megaventory purchase orders?

Yes, the agent can call listpurchaseorders to retrieve raw transaction data, which LlamaIndex then indexes for semantic search. You can ask natural language questions about your spending history and get answers grounded in real ERP records.

Q: Does LlamaIndex support write operations like updatesalesorder in Megaventory?

Yes, you can register updatesalesorder as a function tool within your LlamaIndex agent. The agent can search your knowledge base to resolve an inventory conflict and then execute the update tool to correct the order status.

Q: How does this MCP Server prevent hallucinations in LlamaIndex?

It provides direct access to tools like getinventorystock which supply the exact, real-time numbers. By forcing the agent to retrieve these numbers before answering, you eliminate the risk of the model making up stock counts.

Index your Megaventory ERP data directly into LlamaIndex vector stores for ground-truth supply chain search via this MCP Server.

Perplexity

Turn live ERP records into searchable vector data

`list_products` retrieves your entire catalog so LlamaIndex can convert your physical item descriptions into semantic vectors. Your agent queries this index to find matching parts without requiring exact SKU matches. By embedding the output of `get_product`, you build a retrieval pipeline that understands your inventory relationships. Your queries pull actual live data instead of relying on outdated static spreadsheets.

Query stock levels using LlamaIndex RAG

`get_inventory_stock` feeds real-time warehouse numbers directly into your RAG pipeline to prevent model hallucinations about item availability. This MCP Server ensures your agent answers customer queries using live stock counts rather than guessing. When a user asks if an item is available, the engine calls `get_stock_by_product` to verify the physical count. This live context gets injected into the LLM prompt, forcing the model to stick to the facts.

Automate procurement search index updates

`list_purchase_orders` pulls active supplier transactions to keep your procurement knowledge base current. LlamaIndex indexes these documents so you can search through past orders by vendor name or delivery status. If a shipment is late, the agent calls `list_supplier_clients` to find contact details associated with the pending purchase order. Your search index stays updated because the agent pulls fresh data directly from the ERP.

Setup guide

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