Index Builder.io (Visual CMS) models for RAG

Turn your site data into a searchable knowledge base. By using `get_content`, your agent pulls raw site data that LlamaIndex then embeds into a vector store for semantic search. Your agent stops guessing. It retrieves specific content fragments from your models and provides answers grounded in your actual live site data.

Get pre-rendered HTML in LlamaIndex

Grab the actual layout of your pages using `get_html`. This gives your agent a visual understanding of the DOM structure, which it can then index to improve your search relevance. It bridges the gap between raw data and rendered UI. Your agent now knows exactly how your users see the page.

Maintain content control via LlamaIndex

Use `delete_content` to prune your index when pages are removed. This ensures your vector store stays in sync with your live Builder.io (Visual CMS) environment. Everything stays current. When an agent updates a model, the index refreshes to reflect the change immediately.

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 Builder.io (Visual CMS) tools.",
)
