Enables querying Danish energy data—electricity prices, carbon intensity, consumption, production, grid capacity, balancing markets, and gas—from Energinet's public Energi Data Service without an API key.

MCP server for Durable energy trading analytics that connects Claude Desktop to Snowflake data, enabling natural-language queries about spreads, constraints, generators, and prices.

Enables monitoring and control of SwitchBot devices (temperature sensors, plugs, bots) via Claude Desktop or Home Assistant.

Enables AI assistants to access structured, location-based Swiss energy infrastructure data, including power plants, wind turbines, solar roof potential, and Energiestadt labels, via public APIs without authentication.

Enables controlling ecobee thermostats from ChatGPT by connecting a user's ecobee account through normal browser sign-in, without an ecobee developer API key. Supports listing thermostats, reading status, setting temperature or HVAC mode, and resuming schedules.

MCP server combining TeslaMate historical analytics with Fleet API live data and commands. Works with Claude Code, Claude Desktop, Cursor, and any MCP-compatible client.

Enables AI assistants to search and analyze Turkish electricity and energy market regulation by scanning the Resmî Gazete and EPDK, EPİAŞ, ETKB and TEİAŞ announcements, extracting amended articles and effective dates, and ranking changes by market importance with reasoning. It also provides source health status and rule-based effective-date extraction from any text, without requiring an API key.

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 pull live heating-oil tank readings from their Smart Oil Gauge account without Home Assistant, reporting gallons remaining, percent full, usage rates, and days-until-low estimates plus usage history across daily, weekly, monthly, and yearly windows. It logs in with existing app credentials and fetches fresh data on each tool call, storing nothing on disk.

Exposes five deterministic tools over stdio so LLM agents can evaluate all seven kill methods, plan complete well kills and CWI stripping/snubbing operations, and create or step live simulator sessions without hallucinating safety-critical pressure math. Returns kill mud weight, MAASP, stage-by-stage procedures, rig gauges, kill sheets, and graded debriefs.

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.

Connects Claude Desktop to the Enphase Developer API v4 for read-only access to solar production, consumption, battery, and EV charger data, with optional write tools for battery settings and EV charging.

Unofficial MCP server for Hive (British Gas) smart heating. Lets Claude and other AI assistants check your thermostats, radiator valves, hot water, plugs and lights and, if you allow it, boost the heating, set temperatures, switch on the hot water and set holiday mode. Read-only by default, with an optional audit log of every change. Runs in Docker or as a one-click Claude Desktop bundle.

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 AI agents to retrieve daily European underground gas storage levels, LNG terminal inventory and send-out, facility directories, and planned or unplanned outage reports sourced from the AGSI+ and ALSI+ transparency platforms. Storage and LNG level queries require the user's own free API key, while the directory and outage tools work without one.

Enables MCP clients to watch and drive a running ResInsight, query reservoir simulation models, and render pictures and plots without touching the GUI.

This server enables the retrieval of detailed energy statistics and usage data from home systems without requiring access to a mobile application. It provides real-time access to solar panel performance, home battery status, and dynamic electricity and gas pricing.

Enables querying power outages and affected customers in Chile from SEC public data, including affected customers by date, region and commune, national customer totals, aggregated outage summaries with rankings, and lists of affected regions. Runs locally over stdio so any MCP-compatible client can call its tools without deployment or API keys.

Enables LLM agents to inspect multi-modal IoT telemetry and query safety policies, then dispatch actuator commands through typed MCP tools that enforce deterministic safety interlocks and record a tamper-evident SHA-256 chained audit trail. This lets automated agents control building hardware without violating safety invariants, while rejecting cross-sensor false alarms and cutting redundant telemetry and token usage.

Enables voice assistants to answer when to run household appliances using live solar forecasts, typical-year production, savings, battery, and multi-load planning. It remembers site details, estimates usable solar windows, and returns concise spoken guidance without inventing measurements.

Read-only MCP server for Energinet's public Energi Data Service. Enables dataset search, arbitrary dataset queries with filters, and CO2 emissions retrieval for DK1/DK2 without an API key.

Provides read-only access to Shelly Cloud energy data, including live power, lifetime energy, and historical consumption with cost, enabling AI agents to monitor electricity usage without device control.

Exposes tools to query and analyze energy monitoring sessions stored in CSV files, enabling users to get consumption stats, compare sessions, and view historical data through natural language in Claude Desktop.
