Index metabolic data with LlamaIndex

Turn your `calculate_tdee` results into searchable knowledge by indexing them with LlamaIndex. This lets your agent recall past metabolic states to inform current recommendations. Instead of just running a calculation, the agent stores the context. You get a queryable history of how your metabolism changes over time.

Ground agents in local activity data

The `search_activity_catalog` tool provides a fixed set of MET values that LlamaIndex can embed into your knowledge base. Your agent queries this index before calculating burn rates. This prevents the model from making up activity values. Everything stays tied to the provided local dataset.

RAG-ready weight projections

Use `calculate_weight_loss_projection` to generate data points that your LlamaIndex application can store. The agent can then answer questions about future weight goals based on these hard projections. It connects the math to your existing document store. You can build reports that combine personal health notes with these calculated timelines.

Setup guide

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

Common questions about Metabolic Energy Estimator MCP in LlamaIndex

You wrap the tools in a tool spec and add them to your FunctionAgent. The agent then retrieves data from the server and incorporates it into your vector store.

Once you index the tool outputs, yes. LlamaIndex treats the results as documents, allowing you to ask questions about your weight loss history across multiple sessions.

Absolutely. You can restrict the agent to specific tools using the allowed_tools filter, ensuring it only accesses the metabolic functions you choose.

No. The server operates locally, and LlamaIndex handles the data indexing on your machine. No external APIs are contacted during these calculations.

Your weight and metabolic stats are kept in your local vector index. The server processes the math, and the results are stored in your private, secure knowledge base.
