Common questions

Is Compera safe?

It passed 1 of 1 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 (1.0.1) reached the registry 2 months 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?

Compera MCP Server

Live Swedish price & service comparison as callable tools for AI agents.

Compera (compera.se) is an independent Swedish comparison service for both products and services. This MCP server exposes Compera's daily-fresh data as tools so AI assistants (Claude, ChatGPT, Perplexity, Cursor, …) can answer *"cheapest/best X in Sweden"* in real time — and cite the source.

No API key, no install, no local process. It's a remote server: point your client at one URL.

Endpoint: https://compera.se/mcp — Streamable HTTP, JSON-RPC 2.0
Official MCP Registry: io.github.fredxhansson-cmyk/compera
Docs / landing: https://compera.se/for-ai
Machine-readable map: https://compera.se/llms.txt
License: MIT

Why use it

Grounded, current answers — prices and rates refresh daily; the model stops guessing stale numbers.
Swedish market coverage — electronics & products, plus broadband, mobile, electricity, insurance and loans.
Citeable — every response ends with a Source: line back to compera.se, so answers are attributable.
Zero setup — remote server; add one URL and the tools appear.

Typical prompts it unlocks: *"What's the cheapest [product] in Sweden right now?"*, *"Compare broadband providers"*, *"Today's electricity price in SE3"*, *"Lowest consumer-loan rate available"*.

Tools

Tool	Parameters	Description
`search_products`	`query` (string)	Search the catalog for the cheapest price + number of stores.
`product_offers`	`query` (string)	All store prices for a single product (cheapest / in-stock first).
`compare_category`	`category` (string)	Top providers in a Swedish service category (broadband, mobile, electricity, insurance, loans).
`compare_pair`	`category`, `a`, `b` (strings)	Head-to-head comparison of two providers in a category.
`electricity_price`	`zone` (SE1–SE4, optional)	Daily Swedish electricity spot price per zone (Nord Pool).
`lowest_loan_rate`	—	Lowest effective consumer-loan rate in Sweden right now.
`price_spread`	`query` (string)	How much the same product's price differs between Swedish stores.
`deals_now`	`category` (optional)	Current deals / discounts across categories.
`list_categories`	—	List all comparable service categories.

Every tool returns human-readable text ending with a source line back to compera.se.

-H 'content-type: application/json' \ -d '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"search_products","arguments":{"query":"airpods pro"}}}'

Responses are MCP content blocks of type text, e.g.:

Billigast: AirPods Pro (2nd gen) — 2 490 kr hos 4 butiker.

Data & neutrality

Data is refreshed daily and presented neutrally with source attribution. Compera is an independent comparison service (not owned by any listed provider). Rankings are editorial/quality-led; commercial relationships never override the data shown. Prices and rates are indicative — always confirm the final price with the merchant.
