Build RAG indexes from the Billsby MCP Server

The `list_subscriptions` tool lets your LlamaIndex agent query live billing data and index the results directly into a vector store. Instead of hardcoding lookup paths, your agent searches the indexed tool outputs. When a user asks a complex billing question, the agent locates the relevant records using semantic search rather than raw ID matching.

Ground agent responses in real-time invoice data

The `list_invoices` and `get_customer` tools feed fresh, accurate data directly into the LLM's context window to avoid hallucinations. This guarantees your agent always works with current numbers. If a customer asks why their last bill was higher, the agent pulls the exact invoice breakdown and explains the line items without making things up.

Query subscription plans and add-ons semantically

The `list_plans` and `list_addons` tools allow your LlamaIndex application to search for features that match a user's natural language request. The agent compares the customer's current plan retrieved via `get_subscription` against available options. It then suggests the best-fit upgrade paths based on actual pricing data.

Setup guide

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