Build a Cost Knowledge Base

Don't let your calculations disappear after you run them. With LlamaIndex, every time you use `calculate_hourly_costs` for a piece of equipment, the result can be indexed into a vector store. Over time, you build a private knowledge base of your farm's real-world operational costs. This lets you ask questions like, "Show me the hourly costs for all our John Deere tractors," and get an answer based on your own data.

Query Your Farm's Economics

Go beyond single calculations. Run `calculate_area_impact` for different crops and field sizes, then index all the outputs. Your agent now has a deep understanding of your per-hectare economics. You can then ask complex questions like, "What was the projected cost-per-hectare for harvesting wheat versus soybeans last quarter?" Your LlamaIndex agent retrieves and synthesizes the indexed data to give you a grounded answer.

Ground Answers in Real Numbers

This MCP gives your RAG application a direct line to financial truth. When an agent needs to know the financial trade-offs of buying new equipment, it calls `compare_ownership_models`. The output isn't just a one-time answer; it becomes part of the knowledge base. This ensures future queries about ownership are answered with data from this trusted MCP Server, not a model's best guess.

Setup guide

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

Common questions about Machinery Cost Calculator MCP in LlamaIndex

After getting a result from the MCP, you can manually create a Document object with the output and add it to your index. This gives you full control over what gets stored.

Yes, that's the ideal use case. Use the calculator tools to generate hard numbers, index those numbers, and then build a query engine that answers questions about your farm's finances using that indexed data.

Try asking comparative questions. For example: 'Which of my combines had the lowest cost per hectare last season?' or 'Compare the ownership models we ran for the new sprayer.'

The MCP itself just provides the tools. LlamaIndex is what connects to the vector store. You use the MCP to generate data, then use LlamaIndex's data connectors to save it wherever you want.

The MCP is stateless and only sees the numbers you provide for a single calculation, like machine cost or fuel price. You control the data. Where and how you index the results using LlamaIndex is entirely up to you.
