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 (ChatGPT, Claude, Perplexity, …) can answer "cheapest/best X in Sweden" in real time and cite the source.
