## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1922 tokens (~320/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 77/100
  - Stability observed for 23 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (6)

### `list_zones` (~71 tokens)

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` (~43 tokens)

Data freshness

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` (~403 tokens)

Latest values for a zone

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.

Input parameters:

- `api_key` (string): Optional GridHub API key (ghk_...). Prefer sending it as an 'Authorization: Bearer <key>' HTTP header on the MCP connection; use this argument only if your client cannot set headers. Without a key th…
- `zone` (string, required): Zone id. US ISOs: US-CAISO, US-ERCOT, US-PJM, US-MISO, US-NYISO, US-ISONE, US-SPP. Europe: DE-LU, FR, ES, IT-NO, NL, BE, PL, SE-3, NO-2, DK-1, AT, CH. Great Britain: GB. Australia (NEM): AU-NSW, AU-Q…

### `get_zone_brief` (~421 tokens)

Zone brief (current state in context)

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.

### `get_history` (~559 tokens)

Historical time series

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.

Input parameters:

- `api_key` (string): Optional GridHub API key (ghk_...). Prefer sending it as an 'Authorization: Bearer <key>' HTTP header on the MCP connection; use this argument only if your client cannot set headers. Without a key th…
- `end` (integer): Window end, Unix seconds. Default: now.
- `limit` (integer): Max rows (default 200, max 1000 via MCP; sample mode caps at 50).
- `metric` (string, required): Which series to fetch.
- `start` (integer): Window start, Unix seconds. Default: end minus 24h.
- `zone` (string, required): Zone id. US ISOs: US-CAISO, US-ERCOT, US-PJM, US-MISO, US-NYISO, US-ISONE, US-SPP. Europe: DE-LU, FR, ES, IT-NO, NL, BE, PL, SE-3, NO-2, DK-1, AT, CH. Great Britain: GB. Australia (NEM): AU-NSW, AU-Q…

### `get_map_snapshot` (~219 tokens)

All zones right now

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.
