## What it does

This remote MCP server lets a client search Idescat’s statistics catalogue, inspect a statistic and its tables, and retrieve table metadata or data. Queries can filter by territory, dimension, and period; results can also be rendered as Markdown tables.

For calculations, tools support category sums and derived shares, differences, or percentage changes. Age-based filters are available too. Data comes as JSON-stat, while labels and descriptions are in Catalan, so factor that in when an answer needs to be readable without translation. The endpoint is public and requires no API key; the server is stateless. In Claude Code, add it with `claude mcp add --transport http mcp https://api.idescat.cat/mcp`.
