What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

find_cheapest_fuel_nearby
Find the cheapest petrol stations in Spain near a town, city or point, for one fuel. Returns the best stations by total cost (price plus the fuel used to get there), each with its price per litre, distance, whether it is open, and links to TankoUp and to directions.
find_cheapest_fuel_on_route
Find the cheapest petrol stations along a driving route in Spain, for one fuel. Works out the driving route and returns the best stations within about 3 km of it, by total cost including the detour, with links to TankoUp and to directions through the station. Routes up to 1,200 k
get_province_fuel_prices
Average and lowest fuel prices in a Spanish province, with its cheapest stations. For each fuel: the average and lowest price per litre, the change over the last 30 days, how it compares with the Spanish average, the cheapest brand and the 3 cheapest stations.
get_station_details
Everything about one petrol station: every fuel's current price, opening hours, address and links.

Common questions

Is TankoUp safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 5 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

TankoUp MCP server

Ask Claude, ChatGPT or any MCP client where to fill up for less in Spain.

This is the Model Context Protocol server for TankoUp, the app that finds the cheapest petrol station in Spain. It covers about 12,000 stations: mainland Spain, the Balearic and Canary Islands, Ceuta and Melilla. Prices come from the Spanish government's open data (MITECO) and refresh every 4 hours.

Endpoint: https://mcp.tankoup.com/mcp (Streamable HTTP)
Authentication: none. The data is public and the tools only read it.

"Where is the cheapest diesel near Lucena?"

"I'm driving from Madrid to Valencia tomorrow. Where should I fill up with 95?"

"How much is petrol in Bizkaia compared with the rest of Spain?"

Tools

Tool	What it answers
`find_cheapest_fuel_nearby`	The best stations near a town, city or point, for one fuel
`find_cheapest_fuel_on_route`	The best stations along a driving route, up to 1,200 km
`get_province_fuel_prices`	Average and lowest prices in a province, its 30-day trend, how it compares with Spain, and its cheapest stations
`get_station_details`	Every fuel's price at one station, its opening hours, address and links

Fuels: diesel (Gasóleo A), diesel_premium, sp95 (Gasolina 95 E5), sp95_e10, sp98 and lpg (GLP).

Stations are ranked by total cost, not by pump price alone: the price of a 40 L fill plus the fuel burned driving there and back (or leaving the route and rejoining it). A station 2 cents cheaper but 15 km away usually loses.

Places are Spanish towns and cities by name ("Lucena, Córdoba", "San Sebastián", "Palma"), resolved against every municipality with a fuel station. For a street, a landmark or the user's position, the client passes latitude and longitude.

Every answer is short and structured: a few stations, each with its price, distance, whether it is open now, a link to open it in TankoUp and a Google Maps directions link. Each answer also carries the TankoUp app's App Store and Google Play links.

Connect

Claude (claude.ai and Desktop; it then works on mobile too): Customize → Connectors → Add → Add custom connector, and paste https://mcp.tankoup.com/mcp.

ChatGPT (any plan, Free included): Plugins → Add → Add custom MCP server, paste the URL above and pick "No authentication". Then mention @TankoUp in a chat.

Claude Code:

claude mcp add --transport http tankoup https://mcp.tankoup.com/mcp

Any other client that speaks Streamable HTTP: point it at https://mcp.tankoup.com/mcp.

How it works

Claude / ChatGPT ──MCP──▶ tankoup-mcp (Cloud Run) ──HTTPS──▶ TankoUp API ──▶ Postgres

(the API the app and website use, fed from MITECO every 4 hours)

Python with the official MCP Python SDK (v2), served over Streamable HTTP in stateless mode with JSON responses, so any instance can answer any request.
The server owns no data. Every price comes from the same API that serves the TankoUp apps and website; it never touches the database or the government feed.
Place names resolve offline against a gazetteer of every Spanish municipality with a fuel station (src/tankoup_mcp/data/places.json, built from the API by scripts/build_places.py). No geocoding service, no third party.
Answers are cached in memory for 10 minutes.
Limits: 120 requests a minute per client IP and 600 a minute per instance, at most one instance, and 100 route searches a day.
Runs on Google Cloud Run in europe-west1 (Belgium), scaling to zero when idle.

Privacy

The server keeps no record of what you ask. It logs one line per tool call with the tool's name, the protocol version and how long it took; never the arguments, places or coordinates. Like any web service it sees the caller's IP address, which for Claude and ChatGPT is the platform's, not yours; Google Cloud's request logs keep it for 30 days. Links into tankoup.com and the app stores carry utm_source=mcp, so TankoUp's own analytics can count visits and installs that came through an assistant; nothing about the conversation goes with them. Nothing is shared with anyone. TankoUp's privacy policy: https://tankoup.com/en/legal/privacy-policy.

Run it yourself

Requires Python 3.12+ and uv.

uv sync

TANKOUP_API_KEY=... uv run uvicorn tankoup_mcp.app:app --port 8000

Then open MCP Inspector against http://localhost:8000/mcp:

npx @modelcontextprotocol/inspector

Variable	Default
`TANKOUP_API_KEY`	—	Key for the TankoUp API
`TANKOUP_API_URL`	`https://api.tankoup.com`
`CACHE_TTL_S`	`600`	How long answers are cached
`RATE_LIMIT_PER_IP`	`120`	Requests to `/mcp` per client IP per minute
`RATE_LIMIT_GLOBAL`	`600`	Requests to `/mcp` per instance per minute
`ROUTE_DAILY_LIMIT`	`100`	Route searches per instance per day
`ALLOWED_HOSTS`	empty	Host allowlist; empty turns DNS-rebinding protection off, which is right behind Cloud Run

Tests

uv run pytest

Every tool is tested against a mocked API with real response shapes, plus the HTTP layer: a legacy client's handshake and tool call, rate limits, CORS and health.

Against a running server, scripts/smoke.py calls every tool once:

uv run python scripts/smoke.py https://mcp.tankoup.com/mcp

Deploy

scripts/setup-gcp.sh   # once: the API key in Secret Manager and a service account

scripts/deploy.sh # build in Cloud Build and deploy to Cloud Run
