How to Use the Blended CAC Calculator MCP in LlamaIndex

Q: Can I use LlamaIndex to audit CAC changes?

Definitely. You can run analyzemomtrend and store those resulting trend reports. Later, you query your index by asking about 'CAC volatility in Q2,' and the system pulls up the exact data points.

Q: Does LlamaIndex manage complex Blended CAC Calculator rules?

It manages the data from those rules. The MCP Server handles the calculation logic, while LlamaIndex gives you a semantic search layer over all of your historical financial results.

Build knowledge-augmented AI with LlamaIndex that indexes CAC calculations for better insights.

LlamaIndex & MCP Server

The unique thing here is that the output from an MCP tool call becomes part of your indexed knowledge base. You can run `calculate_cac_metrics` on a quarter's worth of data, and then LlamaIndex stores those results for semantic search later. This means you don't just get a number; you index the full context that led to the number.

Knowledge-Augmented CAC Analysis

Need to query past performance? You can store historical outputs from `analyze_mom_trend` in your vector store. Instead of just showing a graph, you ask a question like 'Why did CAC spike last June?' and get the answer grounded in that specific API data. This turns transient tool output into persistent, searchable business knowledge.

LlamaIndex Budgeting

You can integrate budget recommendations by indexing the structured outputs from `assess_budget_efficiency`. If a new project comes up, your RAG application doesn't guess; it retrieves and summarizes optimal spending percentages based on past successful runs. It’s about giving context to every financial decision.

Setup guide

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

Common questions about Blended CAC Calculator MCP in LlamaIndex

LlamaIndex takes the output of the MCP Server and indexes it. You can search through past calculations—like blended CAC reports—and retrieve specific details from months ago without having to rerun the analysis.

Yeah, because it’s persistent. Running a query gives you an answer *now*. Indexing means that answer, and all its supporting data (the spend amounts and channel names), is stored and retrievable weeks later.

It primarily handles spending data and channel names. The MCP Server records every input array, so your index knows exactly what numbers led to the final cost metrics.

Definitely. You can run `analyze_mom_trend` and store those resulting trend reports. Later, you query your index by asking about 'CAC volatility in Q2,' and the system pulls up the exact data points.

It manages the *data* from those rules. The MCP Server handles the calculation logic, while LlamaIndex gives you a semantic search layer over all of your historical financial results.
