# Compera MCP Server

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

Compera ([compera.se](https://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.

- **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
