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.

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".

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.
