An MCP server for calculating carbon footprints from bank statements using EPA GHG emission factors.

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 for Victron Venus OS that enables reading battery, PV, grid, and inverter data via D-Bus and MQTT, and safely controlling inverter mode and charge limits.

Enables controlling Zaptec EV chargers through natural language, including checking charging status, viewing charge history with cost, pausing and resuming sessions, and setting available current.

Enables an AI assistant to read your own Israel Electric Corporation account over MCP: customer details, contracts, bills, invoice PDFs, meter readings, and smart-meter consumption, with read-only access. Sign-in happens in your own browser and the session is stored only on your machine.

Enables querying optimal control values (angle for blowers, control for pumps) to minimize power given a required flow rate, using machine learning models trained on pump/fan operation data.

MCP server for monitoring and controlling SKYRC MC3000 battery chargers over Bluetooth Low Energy.

Enables turning an address or lat/lng into a transparent solar proposal by geocoding it, pulling Google Solar API building insights (panel layouts, roof segments, imagery quality), and pricing a few system sizes with your tariff, install cost, incentives, savings, payback, NPV and a verdict. Every input is labelled with its source, Google's own financial analyses are shown side by side, and no prices are invented.

Enables steady-state heat transfer calculations for a single horizontal sodium heat pipe within a specified saturation-temperature and power corridor, returning mass flow, wall temperatures, temperature drop, capillary margin, vapor Reynolds and Mach numbers, and flow regime. Inputs outside the supported corridor are rejected.

A local MCP server that enables building energy analysis through tools for anomaly detection, flexible-load schedule optimization, and battery/solar outage-autonomy simulation using reproducible synthetic data.

PyPSA MCP is a Model Context Protocol (MCP) server for creating, analyzing, and optimizing energy system models using PyPSA (Python for Power System Analysis).

MCP server for controlling and monitoring Digital Loggers Power Switch Pro devices, enabling outlet control, power monitoring, and device management through natural language.

Enables controlling and monitoring a Buva EcoStream WTW ventilation unit via natural language, including reading air quality data and adjusting fan settings.

Read-only MCP server for querying Enel Rio de Janeiro's official list of installations using a single tool, hosted with prepaid pay-per-use pricing.

A physics engine for liquid-cooled GPU systems, exposed as an AI-callable MCP server. Enables thermal analysis, coolant comparison, flow optimization, and rack-level sizing via natural language queries.

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.

A TypeScript-based Model Context Protocol (MCP) server with web interface for calculating CO2 emissions using the Climatiq API.

MCP server that estimates photovoltaic production using the European Commission's PVGIS API, deployed on Cloudflare Workers for serverless, free-tier operation.

Exposes Frank Energie energy data (electricity and gas prices, account info) as MCP tools for LLMs, using python-frank-energie for API communication.

Enables consultation of Enel RJ electricity bills through official sources, featuring download and OCR capabilities. It is a read-only MCP server that works with any MCP-compatible client, using prepaid credits.

Connects MCP clients (e.g., Claude) to your NIBE myUplink heat-pump account for reading sensors and controlling settings via OAuth2 authentication.

Turns Google Solar API roof data for a single building into an installer-ready geometry packet with per-segment pitch, azimuth, area, sunshine and derived usable area, steepness, complexity and shading, plus JSON, Markdown and an SVG sketch. Optionally adds pre-GA roof geometry data with facet polygons and obstacles.

Read-only MCP server for consulting CPFL utility data via official source using link and OCR, with prepaid per-query pricing.

WattScope helps teams see the carbon cost of the AI they are already using. Ask Claude to record a piece of work and it attributes the estimated footprint to your organization and to a project, then reports it back — per session, per project, or organization-wide. Every figure is an estimate, and carries the strength of the evidence behind it.

MCP server for consulting and downloading Light utility bills using CEP and OCR from official sources. Offers a single read-only tool with pre-paid pricing, hosted on api.mcp.ai.

MCP server for querying and simulating the dispatch plan of a solar PV + battery system in the Chilean electricity market, using deterministic optimization and optional DRL.

Enables voice control of Nest thermostats from a Pebble Index ring via MCP, using Google's Smart Device Management API to list thermostats, report status, and adjust temperature, mode, eco, and fan settings.

MCP server for controlling Honeywell Total Connect Comfort thermostats, enabling remote management of multiple thermostats through Claude interfaces. It provides tools for monitoring temperatures, adjusting setpoints, and changing system modes for thermostat control.
