Energy and utilities MCP servers are enabling AI agents to simulate power grids, optimize building energy consumption, monitor industrial equipment, track carbon emissions, and access real-time electricity market data — all through natural language. Instead of manually configuring power system simulators or writing SCADA integration code, an AI agent can create an energy system model, run power flow analysis, or dispatch a battery storage system through standardized MCP tools.
The landscape now spans nine areas: power system simulation (PowerMCP with 12 simulators, now at v0.1.0 with a PyPSA-powerio bridge), building energy (EnergyPlus MCP — 35-tool simulation lifecycle from Lawrence Berkeley National Lab, now on EnergyPlus v26.1.0), industrial SCADA (IoT-Edge deleted — replaced by zavora-ai/mcp-scada, a safety-interlocked critical infrastructure platform), energy infrastructure (EnergyAtIt, NREL grid-data-models), grid market data (NEW: EIA energy MCP for U.S. markets, ENTSO-E for Europe, Swiss electricity data), commodity markets (OilpriceAPI v2.0), carbon & sustainability (Climatiq), EV charging (Open Charge Map SDK, pumperly-mcp for real-time prices), and smart home & prosumer (ha-mcp at 3,329 stars, Victron VRM and TCP for solar/battery, HomeWizard P1 smart meter).
The headline findings: PowerMCP hits v0.1.0 — first formal releases June 10 with a new PyPSA-powerio bridge connecting PyPSA modeling to PowerWorld/PSSE/OpenDSS workflows; stars 113→154. ha-mcp explosive growth — 2,558→3,329 stars (+771), v7.7.0 with Read-Only Mode. EnergyPlus MCP upgraded — now runs EnergyPlus v26.1.0, added streamable HTTP transport for cloud deployments. IoT-Edge MCP deleted — the poly-mcp repository is gone (404); zavora-ai/mcp-scada (June 9) is the functional replacement. Grid market data gap narrowing — cyanheads/eia-energy-mcp-server fills the U.S. ISO/RTO gap with EIA API v2 data; RomeCar/mcp-energy-data covers ENTSO-E European markets. Prosumer solar/battery — two Victron MCP servers (VRM cloud + local Modbus/MQTT) arrived. Smart meter — HomeWizard HomeWizard P1 MCP fills the AMI gap for European smart meters.

Power System Simulation
PowerMCP
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| Power-Agent/PowerMCP | 154 | Python | MIT | 12 integrations |
The most ambitious power system MCP project — a collection of MCP servers bridging AI agents to 12 different power system simulation tools. Shipped its first formal releases on June 10, 2026:
- v0.1.0 — initial tagged release covering the full 12-simulator suite
- v0.1.1 — adds the powerio case-conversion server and a PyPSA-powerio bridge connecting PyPSA power modeling to PowerWorld, PSSE, and OpenDSS workflows; CI test suite added
The 12 supported simulators:
- PowerWorld — commercial power flow and stability analysis
- OpenDSS — distribution system simulation (EPRI) — modular tooling split
- PSSE — Siemens PTI power system simulator
- PyPSA — Python for Power System Analysis (open source)
- pandapower — power system modeling and analysis (open source)
- ANDES — dynamic simulation and symbolic modeling
- Egret — EGRET optimization (Sandia National Labs)
- LTSpice — circuit simulation (Analog Devices)
- PSLF — GE Positive Sequence Load Flow
- PowerFactory — DIgSILENT PowerFactory (dominant European TSO tool)
- Surge — Surge power-systems engine with 44 tools
- HOPE — HOPE integration synced with upstream
The PyPSA-powerio bridge is a significant addition — it lets users convert PyPSA models to the PowerIO format used by commercial simulators, enabling round-trips between open-source and proprietary tools within the same AI agent workflow. Stars jumped from 113 to 154 (+41) since April, with new contributor Samuel Talkington joining. Still the only MCP project attempting to unify the fragmented power systems software ecosystem.
PyPSA MCP
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| open-energy-transition/pypsa-mcp | 51 | Python | MIT | 13 |
A focused MCP server for PyPSA energy system modeling through natural language. 13 tools organized into four categories:
- Model management (4 tools) — create, list, delete, export model summaries
- Component creation (5 tools) — add buses, generators, loads, transmission lines, storage units
- Data/simulation (3 tools) — time snapshots, power flow analysis, optimization
- Analysis — results extraction and metric computation
Institutional-backed since transferring to the open-energy-transition organization. Steady at 51 stars (+2 since April) with organic growth; no code pushes since March 2026, suggesting a stable, maintenance-phase project. For teams already using PyPSA, this remains the more practical choice over PowerMCP’s broader approach. The new PyPSA-powerio bridge in PowerMCP v0.1.1 means these two projects now interoperate.
Building Energy Simulation
EnergyPlus MCP (Lawrence Berkeley National Lab)
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| LBNL-ETA/EnergyPlus-MCP | 94 | Python | — | 35 |
The most comprehensive building energy simulation MCP server, developed by the Energy Technologies Area at Lawrence Berkeley National Laboratory. 35 tools across 5 categories for the complete building energy simulation lifecycle.
May 7, 2026 updates (two notable commits):
- Default EnergyPlus updated to v26.1.0 — the latest DOE release
- Streamable HTTP transport with bearer token auth — enables remote and cloud-hosted deployments, significantly expanding use cases beyond local desktop
The streamable HTTP addition is architecturally significant: it means EnergyPlus simulations can now run on dedicated servers and be accessed remotely by AI agents, rather than requiring local installation. For architecture firms and engineering consultancies, this enables shared EnergyPlus infrastructure.
Stars: 83→94 (+11 since April). Actively maintained by LBNL — one of the most credible institutional MCP projects in any category.
Industrial SCADA & IoT
zavora-ai/mcp-scada (new)
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| zavora-ai/mcp-scada | 1 | — | — | Multiple |
New (June 9, 2026). A critical-risk industrial control platform for energy and utilities with safety-interlocked approval gates — the functional replacement for the now-deleted IoT-Edge MCP Server. Key capabilities:
- Asset management — track industrial assets across facilities
- Telemetry — real-time sensor and equipment data
- Alarm systems — multi-priority alarm management
- Safety-interlocked approval gates — dangerous operations require explicit approval before execution, preventing accidental SCADA commands
- Outage analysis — grid and facility outage root cause workflows
- Maintenance scheduling — predictive and scheduled maintenance management
The safety-interlock design is the key differentiator for SCADA use cases. SCADA systems control physical infrastructure — motors, valves, circuit breakers. The approval gate pattern prevents AI agents from executing irreversible operations without human confirmation, which is the right architecture for critical infrastructure.
Note: The previously reviewed poly-mcp/IoT-Edge-MCP-Server (23 stars) has been deleted — the repository returns 404 as of June 2026. Users of that server should evaluate mcp-scada as a replacement.
Energy Infrastructure
EnergyAtIt MCP Server
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| kasathur/energyatit-mcp-server | 0 | JavaScript | MIT | 30+ |
An ambitious energy infrastructure MCP server with 30+ tools for managing distributed energy resources across 8 industrial protocols (IEC 61850, DNP3, Modbus TCP/RTU, OpenADR 2.0b, OCPP 1.6/2.0, IEEE 2030.5, ICCP/TASE.2, REST). Covers battery dispatch, carbon verification, demand response, grid monitoring, and compliance reporting.
Install via npx energyatit-mcp-server. No activity since February 2026 — the protocol breadth is impressive but the project appears dormant. 0 stars unchanged.
NREL Grid Data Models
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| NLR-Distribution-Suite/grid-data-models | 22 | Python | BSD-3 | — |
Maintained by the National Renewable Energy Laboratory (NREL), grid-data-models (GDM) is a Python package containing Pydantic data models for distribution power system assets — now with MCP server capabilities for AI interaction. Actively maintained (latest push June 5, 2026); dependency updates to pandas and the mcp library. 21→22 stars. Complements LBNL’s EnergyPlus MCP — two US national labs in the MCP energy ecosystem.
Grid & Market Data (expanded section)
cyanheads/eia-energy-mcp-server (new)
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| cyanheads/eia-energy-mcp-server | 1 | — | — | Multiple |
New (May 22, 2026). A U.S. Energy Information Administration API v2 MCP server — the closest thing to the long-missing ISO/RTO market data server. Covers:
- Electricity — generation by source, consumption, capacity, regional grid data (CAISO, PJM, ERCOT, MISO feeds via EIA)
- Petroleum — crude oil prices, refinery output, imports/exports
- Natural gas — Henry Hub prices, storage levels, production
- Coal — production, consumption, imports
- Energy forecasts — Short-Term Energy Outlook (STEO) data
Supports both STDIO and Streamable HTTP transports. The EIA’s API v2 is the authoritative source for U.S. energy statistics, and this MCP server makes it accessible to AI agents without custom integration code. Fills a meaningful portion of the ISO/RTO data gap — while not true real-time market prices, the EIA data covers the same grids with hourly and daily resolution.
RomeCar/mcp-energy-data (new)
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| RomeCar/mcp-energy-data | 0 | — | — | Multiple |
New (May 1, 2026; active June 11). An ENTSO-E European power market data MCP server, using DuckDB and Parquet for a high-performance local data store. Exposes:
- Electricity prices — day-ahead and intraday market prices by zone
- Load — actual and forecast grid load
- Generation — by source (wind, solar, nuclear, hydro, thermal)
- Cross-border flows — inter-country transmission
- Outages — planned and unplanned generation and transmission outages
Self-hosted focus — the DuckDB/Parquet architecture means data is cached locally rather than live-queried. Zero stars but actively pushed as of June 11, 2026. Fills the European market data gap that has no equivalent in the existing catalog.
malkreide/swiss-electricity-mcp (new)
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| malkreide/swiss-electricity-mcp | 0 | — | — | 12 |
New (June 3, 2026). A Swiss electricity data MCP server with 12 tools and no API key required:
- BFE Energiedashboard — Swiss Federal Office of Energy dashboard data
- ElCom tariffs — official Swiss electricity tariff data
- OGD consumption — open government data for Swiss electricity consumption
Niche but fills a specific regional gap. Zero stars; early stage.
Commodity Markets
OilpriceAPI MCP Server
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| OilpriceAPI/mcp-server | 3 | TypeScript | MIT | 4 |
Real-time oil, gas, and commodity pricing for AI agents. 4 tools: current commodity price, multi-commodity market overview, side-by-side comparisons, and a catalog of 40+ commodities (WTI, Brent, Henry Hub, EU TTF, coal, refined products, metals, forex). Stars: 1→3 (+2). Install via npx oilpriceapi-mcp — requires an OilpriceAPI key. No code changes since the v2.0 upgrade in March 2026.
Carbon & Sustainability
Climatiq MCP Server
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| jagan-shanmugam/climatiq-mcp-server | 8 | Python | MIT | 10 |
A carbon emission calculation MCP server covering electricity, travel (car/plane/train), cloud computing (AWS/GCP/Azure), freight, procurement, hotel stays, and emission factor search. Requires a Climatiq API key. Install via uv pip install climatiq-mcp-server. Dormant since March 2025 — no code activity in over a year, though the 8 stars are unchanged. The Climatiq API it wraps remains active; the MCP server itself may need maintenance for newer protocol versions.
Smart Home & Prosumer Energy
ha-mcp (Home Assistant)
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| homeassistant-ai/ha-mcp | 3,329 | — | — | Multiple |
| tevonsb/homeassistant-mcp | 568 | TypeScript | MIT | Multiple |
ha-mcp continues its explosive growth — 2,558→3,329 stars (+771 since April), maintaining its position as the dominant Home Assistant MCP implementation by a wide margin. The tevonsb fork (568 stars) is largely stagnant.
v7.7.0 (June 10, 2026) — major new feature: Read-Only Mode toggle
- Web UI toggle and add-on config option
- Hides write tools from the MCP tool catalog entirely — agents cannot see or call any write operations
- Blocks write operations with structured errors when toggled on
options-flowbug fix: now reports persisted values rather than schema defaults
The Read-Only Mode is significant for safety-conscious deployments — it provides a hard boundary preventing AI agents from accidentally controlling smart home devices while still enabling full read/monitoring access. HA container updated to v2026.6.1 via Renovate bot.
While not energy-specific, Home Assistant’s energy dashboard integration means ha-mcp can access solar production, battery state-of-charge, grid import/export, and consumption by circuit — the most widely used energy monitoring MCP in practice.
Victron VRM MCP (new)
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| lubosstrejcek/victron-vrm-mcp | 0 | — | — | — |
New (April 17, 2026; active June 11). A Victron Energy VRM cloud API MCP server for solar, battery, and ESS (Energy Storage System) data. Victron Energy is one of the most popular brands for off-grid and hybrid solar/battery installations. This MCP server connects to the VRM cloud portal, exposing:
- Solar PV production data
- Battery state-of-charge and health
- ESS mode and settings
- Historical energy data
Supports Streamable HTTP transport and MCP Connector compatibility. Zero stars but actively maintained.
Victron TCP MCP (new)
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| lubosstrejcek/victron-tcp | 0 | — | — | — |
New (active June 11). A local LAN Victron GX device MCP server via Modbus TCP + MQTT — no cloud dependency. Exposes real-time solar, battery, grid, and inverter data directly from the local Victron GX device (Cerbo GX, Venus GX, etc.). Complements the VRM cloud server: use victron-tcp for local/offline access and victron-vrm-mcp for cloud/remote access.
EV Charging
Open Charge Map MCP
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| andreibesleaga/ocm-sdk | 3 | — | — | — |
An SDK and MCP server for the Open Charge Map API — the world’s largest open registry of EV charging station locations. Data covers station locations, connector types, availability, and network operator information worldwide. Last push May 29, 2026. A second Open Charge Map MCP implementation (mcp-openchargemap, June 7) also appeared, giving the EV charging space two independent implementations of the same API.
pumperly-mcp (new)
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| pumperly-mcp | 1 | — | — | — |
New (updated June 10, 2026). A real-time fuel and EV charging price MCP server with station search and route planning. Focuses on the pricing dimension missing from the Open Charge Map approach — not just where stations are, but what they cost right now. Covers both traditional fuel stations and EV chargers.
Smart Meters (AMI)
HomeWizard P1 MCP (new)
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| mrksmts/homewizard-mcp-server | 1 | TypeScript | — | — |
New (May 1, 2026). A read-only MCP server for the HomeWizard Energy local API, specifically targeting the P1 smart meter interface common in the Netherlands and Belgium. No cloud API required — reads directly from the HomeWizard device on the local network. Fills the AMI smart meter gap for European users.
Energy Monitoring Hardware
Emporia Energy MCP Server
| Server | Stars | Language | License | Tools |
|---|---|---|---|---|
| emporiaenergy/emporia-mcp | 7 | — | — | — |
The first official vendor MCP server for energy monitoring hardware — Emporia Energy’s whole-home circuit-level energy monitors. Beta status. 6→7 stars (+1). No code activity since August 2025; the official vendor backing remains notable even in dormancy.
What’s Missing
The energy & utilities MCP landscape’s gaps are narrowing, but significant ones remain:
- Real-time ISO/RTO market prices — the EIA server covers U.S. grid data with hourly resolution, but true real-time LMPs (Locational Marginal Prices) from CAISO, PJM, ERCOT, and MISO remain unserved
- Utility billing and customer management — no MCP servers for utility CIS (Customer Information Systems), billing engines, or rate schedule management
- DERMS — no Distributed Energy Resource Management System integration for coordinating solar, storage, and demand response at scale
- Named EV charging networks — no ChargePoint, Tesla Supercharger, or Electrify America API integration; charge session management (start/stop) still missing
- Weather-to-energy forecasting — no solar irradiance or wind speed to energy production prediction pipeline
- Grid resilience — no vegetation management or asset health monitoring (zavora-ai/mcp-scada begins to address outage analysis)
- Nuclear and hydroelectric — no simulation or monitoring tools for these generation types
The Bottom Line
Energy & utilities MCP servers continue their rapid maturation. The scientific simulation layer (PowerMCP v0.1.0 with 12 simulators, EnergyPlus MCP on v26.1.0, two US national labs) is now world-class. The smart home layer (ha-mcp at 3,329 stars, Victron solar/battery, HomeWizard P1 smart meter) is growing fastest. The grid market data layer has finally started filling in — EIA data for U.S. markets, ENTSO-E for Europe, Swiss national data.
The loss of IoT-Edge MCP is notable but offset: zavora-ai/mcp-scada launched days before this refresh with a more safety-conscious design appropriate for critical infrastructure.
The operational utility side (billing, DERMS, real-time ISO prices, EV network integration) remains the last significant frontier. The research and monitoring tools are mature; operational control tools — beyond what SCADA and smart home integrations cover — are still beginning to appear.
This category earns 4/5 — upgraded from 3.5 on the prior refresh. The combination of first formal PowerMCP releases, EnergyPlus cloud deployment capability, the ha-mcp explosion, and the arrival of grid market data tools (EIA, ENTSO-E) marks genuine maturation. The operational gaps are real but smaller than they were two months ago.
