How to Use the ENTSO-E MCP in LlamaIndex

Q: How does LlamaIndex index the XML data from ENTSO-E tools?

The framework takes the raw XML payload from tools like getwindsolarforecast and converts it into document nodes. These nodes are then embedded and stored in your vector database, making renewable forecasts searchable by your LlamaIndex agent.

Q: How do I restrict which ENTSO-E tools a LlamaIndex agent can use?

You can use the allowedtools filter when setting up your McpToolSpec. This allows you to restrict your LlamaIndex agent to read-only endpoints like getdayaheadload while hiding trading-adjacent tools.

Q: Can LlamaIndex update its vector store automatically with ENTSO-E data?

Yes, you can set up a recurring task that calls getdayaheadgeneration through the MCP client and upserts the new data points into your index. This ensures your RAG applications always search against the latest day-ahead projections.

Index live European electricity market data into your LlamaIndex vector store for grounded grid analysis.

Perplexity

Build a queryable index of European power grid data

The `get_actual_generation` tool fetches current power outputs so you can turn live grid metrics into searchable document nodes inside your LlamaIndex knowledge base. Indexing these physical statistics grounds your agent's answers in reality. Instead of relying on static training data, your agent queries live XML payloads from `get_actual_load` to verify regional demand trends. This mechanism prevents hallucinations by forcing the LLM to reference indexed grid data before responding.

Ground LlamaIndex RAG pipelines in real-time prices

The `get_balancing_prices` tool retrieves active market pricing to inject actual grid costs directly into your LlamaIndex semantic search pipelines. RAG applications gain immediate visibility into regional imbalances without relying on stale data. Your agent can cross-reference these real-time prices with historical data retrieved via `get_day_ahead_prices` stored in your vector database. This integration ensures that your automated market reports reflect current financial realities on the European grid.

Track physical grid outages inside your knowledge index

The `get_transmission_outages` tool pulls active network limitations to keep your LlamaIndex knowledge base updated with physical grid constraints. Your agent indexes these infrastructure bottlenecks as they occur to map supply risks. By combining this with `get_generation_outages`, your agent builds a clear timeline of supply risks. This structured context is indexed automatically, enabling your query engine to explain pricing spikes using physical grid events.

Setup guide

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

Common questions about ENTSO-E MCP in LlamaIndex

The framework takes the raw XML payload from tools like `get_wind_solar_forecast` and converts it into document nodes. These nodes are then embedded and stored in your vector database, making renewable forecasts searchable by your LlamaIndex agent.

Yes, you can register this MCP Server as a tool spec within a sub-question query engine. The engine will split a complex query into smaller parts, calling `get_crossborder_flows` and `get_installed_generation` separately to build a complete answer.

You can use the allowed_tools filter when setting up your McpToolSpec. This allows you to restrict your LlamaIndex agent to read-only endpoints like `get_day_ahead_load` while hiding trading-adjacent tools.

Yes, you can set up a recurring task that calls `get_day_ahead_generation` through the MCP client and upserts the new data points into your index. This ensures your RAG applications always search against the latest day-ahead projections.

Your credentials reside in the secure Vinkius V8 Isolate Sandbox, completely separated from your local indexing environment. The LlamaIndex client communicates through this MCP connection using a single encrypted token, ensuring that raw XML power market data is fetched securely without exposing your API keys.
