Gie Storage MCP server

@pipeworx/gie-storage

European natural gas storage and LNG terminal data from Gas Infrastructure Europe (GIE): how full EU gas storage is, by country, operator or site; LNG terminal inventory and send-out; the facility directory; and planned and unplanned outage reports.

Part of Pipeworx — an MCP gateway connecting AI agents to 1800+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

• giegasstorage(country?, company?, facility?, date?, from?, to?, days?, apiKey): daily gas storage level for the EU, one country, one operator or one facility. Covers fill % of working gas volume, gas in storage (TWh), injection and withdrawal (GWh/d), trend and the gas day. With no dates you get the latest gas day. Requires a GIE key.**
• gielngterminals(country?, company?, facility?, date?, from?, to?, days?, apiKey): daily LNG terminal inventory (1000 m³ LNG and GWh), send-out, and declared maximum inventory and send-out. Requires a GIE key.**
• giestoragefacilities(dataset?, country?, query?, include_closed?): lists every storage system operator (or LNG operator) by country, with each facility's name, type, EIC code and operational dates. Use the EIC codes as company / facility in the other tools. Keyless.
• giestorageoutages(dataset?, country?, company?, facility?, type?, from?, to?, limit?, page?): planned and unplanned unavailability reports, newest first. Each report gives the facility, start and end, whether the end is confirmed or estimated, the capacity taken offline and the operator's reason. from/to filter on the publication date. Keyless.

Auth

The two directory and outage tools are keyless. The two level tools are BYO only: GIE refuses storage and LNG level calls without a personal API key. Registration is free at https://agsi.gie.eu/account, and the same key works on both AGSI+ and ALSI+. Pass it as _apiKey. Without a key, the tool refuses with "requires an API key" and points to the keyless tools.

Data sources

• Gas Infrastructure Europe (GIE), AGSI+ Aggregated Gas Storage Inventory: daily underground gas storage levels and storage unavailability reports.
• Gas Infrastructure Europe (GIE), ALSI+ Aggregated LNG Storage Inventory: daily LNG terminal levels and terminal unavailability reports.

Reuse terms: GIE publishes this as public transparency-platform data, and the platform states no reuse licence (checked 2026-10-14). This pack fetches it live for each request and stores no copy, so attribute it to GIE AGSI+ / ALSI+. Every call goes live to GIE, and every response carries source, licence and dataasof. For the level tools, dataasof is the gas day GIE reports.

Notes for the next person:

• An outage filter on a facility is silently ignored by GIE unless the country and operator are also sent. giestorageoutages resolves both from the directory when only facility is given.
• In the outage feed, total is the row count on the current page. last_page is the real page count.
• GIE returns an auth error as HTTP 200 with {"error":"access denied","message":"Invalid or missing API key"}. The pack reads the body and raises the error rather than returning an empty list.
