Enables AI agents to interact with a user's Fill-Rite fuel management system, with token refresh handling for continuous access.

Enables users to look up US residential electricity utilities and plans by ZIP code and usage, then estimate annual bills and rank plans by cost from published tariff data.

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.

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

Enables querying measured GPU energy per million output tokens by model and GPU, estimating energy and CO2e for token counts and grid regions, comparing GPUs, exploring concurrency curves, and retrieving hardware and source metadata.

Enables Alexa+ to answer spoken questions about a home's energy use and act on them through seven voice-first tools, covering live device status, usage and cost reports, waste detection, savings recommendations, automation listing, device control, and confirmed energy-plan application.

MCP server for querying Towngas account data, including bills, readings, and bound accounts. Supports automatic token refresh via refresh token.

Enables AI agents to understand, query, and manipulate Honeybee building energy models through natural language via the Model Context Protocol.
