## Only reads (6)

Looks things up and changes nothing. Claude Code: allow.

### `get_history`

- The name "get_history" says "get": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
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 / get_zone_brief for current values. Default window is the last 24h (last ~400 days for capacity, which is annual). Max window 31 days per call (400 for capacity); paginate with start/end for more. Metrics: price (wholesale, local currency per MWh), demand (MW), generation (per fuel, 'fuel' field set; % or MW depending on zone; GB and US-CAISO only), carbon-intensity (gCO2/kWh; GB only), interchange (net imports, MW), capacity (installed MW per fuel; European zones only). Authentication: send 'Authorization: Bearer <ghk_key>' on the MCP connection (free key, 500 requests/day, instant email signup at https://grid-hub.app/developers), or pay per call with x402 (USDC on Base) via the X-PAYMENT header. With no credentials, data tools run in free sample mode: real, current data but truncated (history capped at 50 rows; brief returns one context block). Sample results are clearly marked.
```

### `get_latest`

- The name "get_latest" says "get": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
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'. Note: some European sources publish day-ahead prices, so the price timestamp can be up to ~36h in the future; use get_zone_brief for a strictly at-or-before-now value with historical context. Authentication: send 'Authorization: Bearer <ghk_key>' on the MCP connection (free key, 500 requests/day, instant email signup at https://grid-hub.app/developers), or pay per call with x402 (USDC on Base) via the X-PAYMENT header. With no credentials, data tools run in free sample mode: real, current data but truncated (history capped at 50 rows; brief returns one context block). Sample results are clearly marked.
```

### `get_map_snapshot`

- The name "get_map_snapshot" says "get": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
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 requests/day, instant email signup at https://grid-hub.app/developers), or pay per call with x402 (USDC on Base) via the X-PAYMENT header. With no credentials, data tools run in free sample mode: real, current data but truncated (history capped at 50 rows; brief returns one context block). Sample results are clearly marked.
```

### `get_status`

- The name "get_status" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_zone_brief`

- The name "get_zone_brief" says "get": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
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 generation mix where published (GB, US-CAISO), and a one-sentence plain-English summary. Best tool for questions like 'is electricity cheap/clean in X right now' or 'is this a good time to run a flexible workload'. A raw price means little without this context. Authentication: send 'Authorization: Bearer <ghk_key>' on the MCP connection (free key, 500 requests/day, instant email signup at https://grid-hub.app/developers), or pay per call with x402 (USDC on Base) via the X-PAYMENT header. With no credentials, data tools run in free sample mode: real, current data but truncated (history capped at 50 rows; brief returns one context block). Sample results are clearly marked.
```

### `list_zones`

- The name "list_zones" says "list": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
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.
```
