How to Use the Google Analytics 4 MCP in LlamaIndex

Q: How does LlamaIndex index data from the Google Analytics 4 MCP Server?

You initialize the connection using BasicMCPClient and convert the MCP tools into LlamaIndex tools using McpToolSpec. The output of tools like runreport is then ingested, chunked, and loaded into your vector store for semantic retrieval.

Q: Can I use LlamaIndex to query Google Analytics 4 data offline?

Yes, once your LlamaIndex pipeline runs tools like gettrafficsources and indexes the results, you query that historical data without making fresh API calls. This is ideal for analyzing weekly or monthly performance trends without hitting GA4 rate limits.

Q: How does the Google Analytics 4 MCP Server tool schema map to LlamaIndex agent tools?

The MCP Server automatically translates schemas like runpivotreport into standard LlamaIndex tool definitions. Your FunctionAgent inspects these schemas to understand exactly what parameters, like date ranges or dimensions, it needs to provide.

Q: Can I filter which Google Analytics 4 tools are available to my LlamaIndex agent?

Yes, you use LlamaIndex's allowedtools filter when initializing your tool spec. This lets you restrict your agent to safe reading tools like getpageviews while blocking administrative or heavy reporting actions.

Index live Google Analytics 4 metrics directly into LlamaIndex to query your site performance using natural language.

Index GA4 Metrics into LlamaIndex Vector Stores

`get_metadata` pulls the complete list of available dimensions and metrics directly into your LlamaIndex knowledge base. Your pipeline indexes this schema information so your RAG setup knows exactly what data points are available for querying. This prevents your agent from hallucinating non-existent dimensions during complex analytical tasks. By grounding your index in the actual GA4 metadata, your queries return precise, schema-compliant results every time.

Search Historical Traffic Data with RAG

`get_page_views` fetches your top-performing pages and loads the resulting view counts into a searchable vector index. LlamaIndex queries this index to answer natural language questions about your most popular content. Instead of pulling fresh reports for every question, your system searches past tool outputs to find immediate answers. This reduces your GA4 API quota consumption while keeping your analytical responses incredibly fast.

Analyze Audience Segments via Semantic Querying

`get_user_demographics` extracts detailed audience profiles, which your LlamaIndex agent converts into searchable document nodes. The agent then combines this demographic data with `get_device_breakdown` to build a multi-dimensional view of your users. You then query this unified index to find correlations between device preferences and user age groups. This turns raw, isolated analytics tables into an interactive, natural-language knowledge base.

Setup guide

Set up Google Analytics 4 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 Google Analytics 4 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 Google Analytics 4 tools.",
)
response = await agent.run("List recent Google Analytics 4 data")
