Index live Joomla content into LlamaIndex

The `list_site_articles` tool feeds your LlamaIndex pipelines with real-time text from your Joomla CMS. Instead of relying on stale database dumps, your indexer pulls active posts directly from the live site to update your local LlamaIndex vector store. This setup lets you build LlamaIndex search systems that query actual published Joomla data. Because you can filter by state, your RAG application only retrieves published information, keeping draft content private.

Ground agent answers in actual Joomla data

This MCP Server provides `get_article_details` to let your LlamaIndex query engine pull full Joomla HTML content on the fly. When a user asks a highly specific question, the engine fetches the exact article to construct its response. This eliminates hallucinations by grounding every LlamaIndex answer in your actual Joomla pages. You can also use `list_system_tags` to filter search results so your engine only looks at relevant topics.

Keep your knowledge base synced with site menus

The `list_site_menus` tool allows your indexer to understand the structure of your Joomla site within LlamaIndex. LlamaIndex maps this menu hierarchy to weigh search results, prioritizing pages that sit on your main navigation. Combine this with `list_global_categories` to build a structured LlamaIndex of your entire Joomla site taxonomy. Your query engines can then parse content based on how it is actually organized on your live server.

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()
