Perplexity

Build a knowledge base from BigCommerce data

Feed the output of `list_products` and `get_product_details` directly into your vector store. Your LlamaIndex application converts this raw API data into searchable embeddings. Query your store metadata using natural language instead of rigid filters. This turns your catalog into a source of truth for your agent's responses.

Ground LlamaIndex answers in real-time store info

Use `get_store_info` to provide context for your agent's knowledge retrieval tasks. This prevents the agent from hallucinating about store configurations or active settings. Your application combines live API results with indexed documents. This ensures your LlamaIndex setup always references current product details.

Filter BigCommerce catalog results before indexing

Apply specific criteria to `list_catalog_brands` to limit the data ingested by your index. This keeps your vector database clean and relevant to your specific use case. Manage the size of your index by selecting only the necessary product metadata. This efficient ingestion keeps your LlamaIndex queries fast and accurate.

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