## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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)

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 82, +1)

No change was recorded against any check on this day. Stability & Change Management went from 13 to 17. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 5 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (5)

### `generation_by_fuel` (~159 tokens)

Great Britain half-hourly electricity generation by fuel type (Elexon BMRS FUELHH dataset). Returns MW generated per fuel (CCGT/gas, COAL, NUCLEAR, WIND, BIOMASS, NPSHYD hydro, PS pumped-storage, OCGT, OIL, and interconnector flows INTFR/INTIRL/etc) for each half-hour settlement period. Keyless. 48 settlement periods per day.

Input parameters:

- `from` (string, required): Publish-time start, ISO datetime, e.g. "2024-06-01T00:00Z".
- `to` (string, required): Publish-time end, ISO datetime, e.g. "2024-06-01T01:00Z".

### `system_demand` (~111 tokens)

Great Britain half-hourly electricity system demand outturn in MW (Elexon BMRS ITSDO dataset) over a required ISO-datetime window; returns one row per settlement period with settlementDate, settlementPeriod, and demand fields.

Input parameters:

- `from` (string, required): Start, ISO datetime, e.g. "2024-06-01T00:00Z".
- `to` (string, required): End, ISO datetime, e.g. "2024-06-01T01:00Z".

### `elexon_list_datasets` (~168 tokens)

Directory of all 84 Elexon BMRS Insights datasets available to query_dataset: the dataset code, what it holds, and which window parameters its route takes (publish time, from/to, settlement date + period, measurement time, or submission time). Covers generation outturn and forecasts, demand and load, balancing mechanism bids/offers and acceptances, market index prices, system frequency, temperature, credit default and system warning notices, and the REMIT outage messages. Search by keyword to find the code for a subject before calling query_dataset. Keyless.

Input parameters:

- `search` (string): Optional case-insensitive keyword matched against the dataset code and its title, e.g. "wind", "demand", "price", "forecast". Omit to list all 84.

### `elexon_system_prices` (~139 tokens)

Great Britain electricity imbalance prices for a settlement day: system buy price and system sell price per settlement period, in GBP/MWh, plus the price derivation code, reserve scarcity price and net imbalance volume (Elexon DISEBSP). This is the cash-out price the balancing market settles at. Keyless. Elexon serves it outside the /datasets routes, so query_dataset cannot reach it.

Input parameters:

- `settlement_date` (string, required): Settlement date, e.g. "2026-08-27".
- `settlement_period` (number): Optional settlement period 1-48. Omit for the whole day (48 rows).

### `query_dataset` (~366 tokens)

Fetch records from any of the 84 Elexon BMRS Insights datasets by its dataset code (MID market index/day-ahead prices, FUELHH generation by fuel, WINDFOR wind forecast, FREQ system frequency, TEMP temperature, REMIT outages, BOD/BOALF balancing bids and acceptances, and 77 more — call elexon_list_datasets for the directory). Pass a code and a datetime window; the correct window parameters for that dataset are chosen automatically. Keyless. Returns the raw records.

Input parameters:

- `dataset` (string, required): Dataset code, case-insensitive, e.g. "MID", "FUELHH", "WINDFOR", "FREQ", "REMIT". Use elexon_list_datasets to find one; an unrecognised code is rejected with the full list rather than passed upstream.
- `date_param` (string): Rarely needed — the window style is looked up per dataset. Pass "publishDateTime", "from", "settlement" (settlementDateFrom/To, which only FUELHH and FUELINST accept), "settlementDate", "measurement"…
- `from` (string, required): Window start, ISO datetime. For settlement-date datasets (B1610, MDB, MDO, PN, QPN, TUDM) this is the settlement date and settlement_period is also required.
- `settlement_period` (number): Settlement period 1-48. Required only for the settlement-date datasets B1610, MDB, MDO, PN, QPN and TUDM, which Elexon serves one period at a time.
- `to` (string, required): Window end, ISO datetime. Ignored for settlement-date datasets.

## Common questions

### What is the Elexon MCP server?

Elexon is an MCP server listed in the public MCP registry as io.github.pipeworx-io/elexon. Elexon BMRS Insights MCP, Great Britain electricity grid & market data. This page covers its npm package (@pipeworx/mcp-elexon).

### Is the Elexon MCP server safe to use?

Elexon scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Elexon MCP server expose?

Elexon exposes 5 tools: generation_by_fuel, system_demand, elexon_list_datasets, elexon_system_prices, query_dataset. Their descriptions and schemas cost roughly 943 tokens of context every time the server is loaded.

### Is the Elexon MCP server still maintained?

Elexon is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Elexon MCP server under?

Elexon declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
