"Popular MCP tools commonly used by programmers" matching MCP servers:

Enables natural-language interaction with Ladybug Tools for building performance simulation, 3D modeling, and data visualization, allowing agents to perform complex environmental analysis tasks without CAD software.

MCP server providing deterministic, standards-traceable engineering calculations for combined-cycle power plant balance-of-plant design, such as fluid properties, pipe sizing, pump NPSH, and valve sizing, with every result including method, assumptions, and warnings.

87+ specialized tools for German and European energy data. Direct AI access to Marktstammdatenregister (MaStR), ENTSO-E, Redispatch 2.0, and Grid Operations for utilities and datacenters.

Enables AI agents to search U.S. hydraulic fracturing disclosure records — well-level frac job details (operator, API number, location, dates, base fluid volumes) and the disclosed chemical additives per job — by state, county, operator, or API number, plus lookups of where a given chemical has been used by CAS number. Responses include source, license, and coverage-window metadata so callers can distinguish missing data from out-of-window disclosures.

Enables querying real-time SPP electricity data—generation mix by fuel, load and renewable forecasts, five-minute LMP prices, and the full marketplace file archive back to 2013—through MCP tools.

Enables querying monthly oil and gas production, consumption, imports, exports, and closing stocks by country, with tools for time-series lookups, cross-country comparisons, and coverage checks.

Enables access to PJM Interconnection's real-time wholesale electricity prices by node, generation by fuel type, and seven-day load forecasts through MCP tools for feed lookup, LMP, fuel mix, and load forecast queries.

Hourly electricity grid carbon intensity (gCO2eq/kWh) for 45 zones across Europe, the US and Great Britain, computed from ENTSO-E, EIA and NESO generation data. Four read-only tools; every value carries its interval timestamp and how stale it is. No API key, no account.

Unofficial MCP server for the messdienst24.de utility portal, providing tools to retrieve heating and hot-water consumption data, download PDF reports, and compare usage trends.

Enables MCP clients to search Colombian energy and gas resolutions and legal opinions, read them in chunks or by internal search, and explore each rule's regulatory graph with validity computed from the texts themselves.

An MCP server for US electricity demand and weather data that provides tools, resources, and prompts to query hourly demand, daily demand, peak demand, and demand vs temperature across regions, all running locally with a bundled SQLite database.

An MCP server that exposes the U.S. Energy Information Administration (EIA) Open Data API, enabling LLMs to browse and query energy data across 17 datasets with generic, composable tools.

MCP server for fetching Danish electricity spot prices (DK1/DK2) using the free elprisenligenu.dk API, providing tools to get current price, cheapest hours, and price summaries.

MCP server for the German energy market master data register (MaStR), enabling querying of energy units, actors, grid connections, and more via 21 SOAP and public tools.

Carbon-aware MCP scheduler that defers "do it later" / "by tomorrow" / "overnight" LLM tasks to the cleanest electricity-grid hour inside a deadline — 40-70% lower CO2 per task, 50% cheaper via Anthropic/OpenAI Batch APIs. 9 MCP tools, per-task carbon receipts to local SQLite, Apache-2.0.

Enables AI clients to automate Spanish energy efficiency certificates by ingesting cadastral, BIM, and field data, applying CTE DB-HE climate and envelope calculations, and producing CE3X project files, official XML records, and homologated PDF certificates.

Enables AI agents to choose the lowest-carbon cloud region for a workload, with tools for ranking regions by carbon intensity and latency, and for finding optimal start times to reduce emissions.

Enables querying and downloading Equatorial Energia invoices via MCP tools, supporting listing consumer units, listing invoices, and downloading second-copy PDFs with local data extraction.

Enables querying SCAU dormitory electricity usage, balance, lifetime consumption, and cost calculations through read-only MCP tools.

Connects Claude and other MCP clients to myGEKKO building controllers via the official Query API, enabling natural-language queries and control of smart-home devices. It is read-only by default, with write actions available only through explicit opt-in and safety policies.
