Grounding Answers in Billing Data

The `get_account` tool retrieves comprehensive details for a specific Younium customer account. By indexing this output, your knowledge-augmented AI can answer questions about billing history based on actual API data. When you query past sessions or configurations using the index derived from `get_account`, the results are grounded in real account records, eliminating guesswork.

Searching Subscription Details

Want to know about a specific billing agreement? The `get_subscription` tool fetches all details for that subscription, including its historical versions. Indexing this data allows your agent to answer complex questions like, 'What was the rate structure in Q2?' This is crucial for building RAG applications where live API data must be combined with documents for accurate context.

Listing and Analyzing Invoices

Using `list_invoices` provides a list of all billing documents generated by Younium. Indexing these results means your AI client can search across hundreds of invoices to find specific payment dates or amounts. It's perfect for compliance queries: you ask the knowledge base, and it points directly to the relevant invoice record.

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.

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 Younium 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 Younium tools.",
)
response = await agent.run("List recent Younium data")
