"How to perform SELECT queries in PostgreSQL" matching MCP servers:

MCP server that enables Google ADK agents to triage solar fault signals, retrieve Salesforce diagnostics via hosted MCP prompt templates, and create WorkOrder records when replacements are needed.

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.

DeepPVMapper is an open source, crowdsourced verified AI map of rooftop solar systems. The MCP serves as a endpoint to allow queries to the database (1.1M+ systems) in natural language. This work is based on my former PhD work.

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.

Enables AI assistants to query Tesla vehicle data and analytics from a TeslaMate PostgreSQL database, including battery health, driving statistics, charging sessions, and custom SQL queries.

MCP server enabling AI assistants to automatically perform carbon footprint modeling, product queries, and emission analysis via the Carbonstop Cloud API.

Enables portable-battery outage planning by exposing tools that retrieve an example scenario, compute usable AC energy and runtime, select protected and optional loads, and compare plans under energy, continuous-power, and startup-surge limits. It returns structured calculations and spoken summaries for rehearsing what can stay powered before an outage.

Enables access to US Energy Information Administration statistics including production, consumption, prices, exports, and more, with series search and natural-language queries.

Provides electricity tariff queries and rate calculations for US utilities, enabling cost estimation and optimal charging schedules.

Provides LLMs with access to news and information about renewable energy projects and planning in Germany via the Nefino API, enabling location-based queries with topic and date filtering.

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.

MCP server for the Carbon Interface API (v1), enabling AI agents to estimate carbon emissions through natural language queries via Pipeworx gateway.

Enables real-time access to US electricity generation, fuel mix, and demand data through natural language queries.

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.

Enables users to compare and select multi-carrier freight routes by applying GLEC emissions factors across air, rail, maritime, and electric ground modes while weighing transit time and landed cost. It also calculates the resulting CO2 footprint and generates verified carbon offset credit allocation certificates for the chosen route.

Enables AI assistants to perform campervan electrical calculations, payload checks, component spec lookups, and semantic search over van build manuals.

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.

An unofficial read-only MCP server for Panasonic AiSEG2 home energy management controllers, enabling clients to read live power flow, per-circuit consumption, circuit names, daily totals, and historical energy/cost data from the device's local web interface.

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.

An MCP server that lets an MCP client control IKEA TRÅDFRI smart plugs paired to a DIRIGERA hub via its local REST API.
