## Tools (as reported by the server, not verified)

- `list\_zones`: List the 25 electricity grid zones GridHub covers, with id, name, data source \(EIA, ENTSO-E, NESO, AEMO\), timezone, currency, licence and required attribution. Free, no credentials needed. Call this first if you are unsure which zone id to use.
- `get\_status`: Ingestion health per source and zone: last successful fetch timestamp and last error, if any. Free. Use it to explain stale or missing values before drawing conclusions from them.
- `get\_latest`: The most recent value of every metric one zone publishes \(price and demand for every zone; generation by fuel for GB and US-CAISO; carbon intensity for GB; interchange where available\), each with unit and timestamp. This is the right tool for 'what is the price/demand/carbon intensity in X right now
- `get\_zone\_brief`: Composite, interpretation-ready snapshot of one zone: current price / demand / carbon intensity where published \(strictly at-or-before now\), each ranked against that zone's own last \~30 days \(percentile, vs-median %, min/max, sample count and the actual data window\), a 24h trend per metric, the gene
- `get\_history`: Time series for one metric in one zone over a start/end window \(Unix seconds\). Rows are returned oldest-first and the 'limit' truncates from the OLDEST end, so a small limit over a wide window returns old data, not recent data — for 'the latest N points' set start close to now, or use get\_latest / g
- `get\_map\_snapshot`: Current headline values for all 25 zones in one call — the cheapest way to compare zones \(e.g. 'which European zone has the lowest price right now', 'rank US ISOs by demand'\). Rebuilt every 5 minutes. Authentication: send 'Authorization: Bearer \<ghk\_key\>' on the MCP connection \(free key, 500 request
