Most integrations tell you what they do; this one spends as much space telling you what it will not answer and which zones return no data at all. That is exactly right for a signal an agent will act on — if the Australian zones have no public day-ahead data, an assistant asked when to charge the car needs to say so rather than produce a schedule from nothing. The response fields are built for that too: a completeness flag, a rank, and an explicit unavailable state.
A remote MCP server giving an assistant the current electricity price, the cheapest hours in the next 24 hours, and available contract comparisons. It is positioned the way weather data is: a hallucinated price is not acceptable, so when data is missing the correct answer is to say so rather than interpolate. The same signals are also available as plain REST endpoints.
- `spot_price` — the real-time price for a zone
- `cheapest_hours` — the cheapest slots in the next 24 hours for a zone, with `hours` and `window` parameters, returned alongside signals about right now: an `energy_state` of cheap, normal or expensive relative to the daily average; a `current_hour_rank` in today's distribution; `current_hour_is_cheap`; `next_cheap_hour` and `hours_until_next_cheap`; `cheap_window_ends`; `cheap_hours_remaining_today`; a `best_3h_window` with its average price; and `avoid_hours` for the above-average slots
- `best_energy_contract` — the best spot contract, the best fixed contract, and an overall recommendation as separate categorised options, taking annual consumption and heating type; it deliberately does not make the spot-versus-fixed decision for you
- A `data_complete` flag and an `available: false` response for zones with no day-ahead data, rather than a fabricated number
- Coverage of 40+ countries and 100+ zones across Europe, Oceania, North America, Asia and Africa, with a per-zone table stating exactly which of spot price, cheapest hours and contract comparison each one supports
- Documented provenance per market — CAISO day-ahead updated daily, ERCOT real-time 15-minute data, NYISO real-time 5-minute, IESO real-time 5-minute, JEPX day-ahead in JPY per kWh, and regulated tariffs rather than spot markets for South Africa and the Philippines
No account, no key, no authentication — the MCP endpoint is `https://elecz.com/mcp`. The equivalent REST endpoints are `/signal/spot`, `/signal/cheapest-hours`, `/signal/contract` and `/signal`, all taking a zone. Know what it does not cover before wiring it in: gas, oil, district heating and water; solar output; bills, grid fees, taxes and meter settings; personal account data; history older than 24 hours; forecasts beyond 24 hours; and any zone not in the published table. It also does not control devices or home automation — scheduling decisions have to account for deadlines and device constraints it knows nothing about. MIT licensed.
