fuel-prices

What petrol, diesel and LPG cost across Europe — 28 countries, weekly, back to 2005.

Part of Pipeworx — an MCP gateway connecting AI agents to 1683+ live data sources.

Tools

| Tool | Answers | |---|---| | fuel_price | "What does petrol cost in Portugal?" — current price per litre for one country. | | compare_fuel_prices | "Where is diesel cheapest in Europe?" — every country ranked, within one week. | | fuel_price_history | "How much has petrol gone up in Germany this year?" — weekly series plus the change. | | fuel_price_coverage | What countries, weeks and fuels are in scope, and how fresh the newest week is. |

Data sources

The European Commission's Weekly Oil Bulletin:

• Landing page: https://energy.ec.europa.eu/data-and-analysis/weekly-oil-bulletin_en
• Series: Weekly_Oil_Bulletin_Prices_History_maticni_4web.xlsx

EU Member States report retail prices into it every week under Council Decision 1999/280/EC, and the Commission publishes the consolidated series. Coverage is the 27 EU states plus the United Kingdom, plus an EU-wide aggregate under the code EU.

Reading the numbers

• Prices are per 1000 litres in the source. Petrol, diesel, heating oil and LPG are quoted that way; a raw 2143 is €2.143 per litre. Every response carries price_per_litre_eur already converted, and the raw figure alongside it with its unit.
• The two heavy fuel oils are quoted per tonne, so they have no per-litre price at all. price_per_litre_eur is null for those rather than a fabricated conversion.
• It is a national average for a week, not a live station price. The newest week is a few days behind and any individual filling station will differ. Every response states its week_ending so a figure cannot be quoted as "today" by accident.
• EU is an aggregate, not a country. It is available to ask for directly but is excluded from compare_fuel_prices rankings.
• Comparisons are pinned to one week. A country that reports late would otherwise win a "cheapest" ranking on an older, lower figure.
• Not covered: the United States, Switzerland, Norway, Turkey, and everywhere else outside the EU and the UK. Asking for one returns an explicit country_not_covered refusal naming the reason rather than an empty result.

Refreshing

Weekly, when the Commission republishes the bulletin:

node scripts/ingest-eu-oil-bulletin.mjs              # full history
node scripts/ingest-eu-oil-bulletin.mjs --weeks 8    # just the recent tail

The script parses the workbook with no dependencies — xlsx is a zip of XML, and node ships zlib — and upserts by (country_code, week_ending, fuel), so a week that stops being republished keeps its last known value.

It refuses to load rather than warn in two cases, because both would otherwise produce a plausible series that is wrong:

• the newest week it parses is more than 45 days old (the source is newest-first, so a layout change silently yields January 2005);
• any record loses its unit.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "fuel-prices": {
      "url": "https://gateway.pipeworx.io/fuel-prices/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/fuel-prices/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1683+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/fuel_price \
  -H 'Content-Type: application/json' \
  -d '{"country":"Portugal"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/fuel_price. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "fuel-prices": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-fuel-prices"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-fuel-prices

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Fuel Prices data" })

The gateway picks the right tool and fills the arguments automatically.
