Enables users to verify whether smart-home commands caused the expected physical and electrical outcomes, diagnose appliance faults, enforce safety cutoffs, and analyze energy usage, tariffs, and bill forecasts through MCP tools.

UK solar PV and heat pump calculators following the MCS standards, plus home energy guides, as a CLI and local MCP server.

Enables access to European electricity data including day-ahead prices, probabilistic forecasts, carbon intensity, and cheapest-window optimization for 43 bidding zones.

Enables users to query current and historical UK electricity carbon intensity, generation mix, and regional intensity data to schedule energy-intensive tasks during low-carbon periods.

Browse and query the U.S. Energy Information Administration API v2 — electricity, petroleum, natural gas, coal, forecasts, and more via MCP. STDIO or Streamable HTTP.

This MCP server provides a single read-only tool to query official CPFL (electric utility) bill download data via a hosted, prepaid service without requiring platform credentials.

Enables users to query the UK National Grid's carbon intensity data, providing real-time and forecasted carbon emissions for electricity generation.

Unofficial MCP server for Octopus Energy customers in the UK. Lets Claude and other AI assistants read your smart meter usage, costs, tariffs and bills, find the cheapest Agile half-hours and, if you allow it, manage Intelligent Octopus EV charging and join Saving Sessions. Read-only by default, with an optional audit log. Runs in Docker or as a one-click Claude Desktop bundle.

Provides real-time grid carbon intensity, power generation breakdown, and carbon-intensity forecasts for any zone or lat/lon location.

Enables AI agents to query UK energy tariffs and products via the Octopus Energy public API.

Weather files (EPW/DDY) for building energy simulation, on-demand. Four tools: search the 17,000-station catalog, analyze any EPW (design conditions, HDD/CDD, DesignDay IDF emit), render 5 chart types (diurnal, wind rose, temp carpet, monthly box plot, comparison), and generate TMY/AMY/CMIP6-morphed scenarios with UHI, extreme events, and wildfire smoke overlays. 3 of 4 tools work without API key.

Enables access to real-time electricity data for a 15-state US region plus Manitoba: fuel mix, five-minute wholesale prices, binding transmission constraints, load and forecasts, and wind/solar output. Can run as a remote MCP endpoint or a local stdio server with no authentication.

Generates EnergyPlus weather files (EPW, DDY, STAT) for any coordinates: actual years from 1990, typical years and future climate to 2100, plus ASHRAE design conditions and nearest weather stations.

Enables AI assistants to list demo inverter sites, inspect production, pull weather context, and get deterministic panel-cleaning recommendations over MCP using synthetic solar operations data.
