Voltcast MCP server

What it does

MCP server for accessing European day-ahead electricity prices across 47 bidding zones, probabilistic price forecasts with published accuracy metrics, carbon intensity data, and tools to find cheapest time windows for energy use. For developers building applications that need real-time or historical electricity pricing and carbon data across Europe.

• Check current and historical day-ahead electricity prices for specific European zones to understand energy cost patterns.
• Retrieve probabilistic price forecasts (P10/P50/P90 depending on plan) with daily published accuracy benchmarks to inform scheduling decisions.
• Find the cheapest contiguous 48-hour window to schedule energy-intensive tasks and identify grid carbon intensity for eco-conscious load shifting.

Tools this server exposes

Tool	Does
list_zones	Returns the registry of 47 European bidding zones with their codes, names, and currencies.
get_prices	Retrieves day-ahead electricity prices for a specified zone and date at 15-minute market intervals, with history back to 2015.
get_forecast	Returns probabilistic price forecasts (P50 on lower tiers, P10/P90 on Pro+) with daily accuracy benchmarks published by Voltcast.
get_carbon	Provides current carbon intensity and green score based on live electricity generation mix for a zone.
get_renewables	Returns wind and solar forecasts from TSO data and Voltcast model compared against actual realized values.
cheapest_window	Identifies the cheapest contiguous time window within the next 48 hours to schedule a load (Pro+ accounts only).

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
