🏛️ Spain AI Kit 🇪🇸

🌍 Spain's Open Data Landscape

Spain runs one of Europe's most extensive public data infrastructures. The Boletín Oficial del Estado traces its lineage to the Gaceta de Madrid — first published in 1661 — and today publishes every national law, royal decree, and official announcement as structured open data. The Instituto Nacional de Estadística exposes thousands of statistical series through a public JSON API. The Catastro offers free cadastral lookups for every property in the country. AEMET serves forecasts for more than 8,000 municipalities across Spain's 17 autonomous communities and two autonomous cities.

The problem: most of this is locked behind XML envelopes, SOAP endpoints, Spanish-only documentation, and idiosyncratic JSON-stat formats. Spain AI Kit makes it usable from an AI assistant in one line of config.

• 12,000+ consolidated Spanish laws queryable as Markdown (national + all 17 autonomous communities)

• 70+ statistical operations from INE — demographics, economics, employment, housing, tourism

• 50 provinces, 8,000+ municipalities covered for address and cadastral lookups

• Daily BOE gazette searchable by date, keyword, subject, or legal scope

• Weather, UV, fire risk, and beach forecasts for the whole country

📖 What is Spain AI Kit?

Spain AI Kit is a collection of MCP (Model Context Protocol) servers that connect AI assistants — Claude Desktop, Claude Code, Cursor, and anything else that speaks MCP — directly to Spanish government open data APIs. No scraping, no API wrangling, no translating Spanish JSON-stat by hand.

🎯 What is MCP?

Model Context Protocol is an open standard that lets AI applications plug into external data sources and tools through a consistent interface. Each Spain AI Kit package is a standalone MCP server you can install and mount independently — use one, use them all, or compose them with other MCP servers.

Inspired by estonia-ai-kit by Stefano Amorelli.

🚀 Quick Start

Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "spain-ine": {
      "command": "npx",
      "args": ["@spain-ai-kit/ine-mcp-server"]
    },
    "spain-boe": {
      "command": "npx",
      "args": ["@spain-ai-kit/boe-mcp-server"]
    },
    "spain-catastro": {
      "command": "npx",
      "args": ["@spain-ai-kit/catastro-mcp-server"]
    },
    "spain-aemet": {
      "command": "npx",
      "args": ["@spain-ai-kit/aemet-mcp-server"],
      "env": {
        "AEMET_API_KEY": "your-api-key-here"
      }
    }
  }
}

Claude Code

claude mcp add spain-ine -- npx @spain-ai-kit/ine-mcp-server
claude mcp add spain-boe -- npx @spain-ai-kit/boe-mcp-server
claude mcp add spain-catastro -- npx @spain-ai-kit/catastro-mcp-server
claude mcp add spain-aemet --env AEMET_API_KEY=your-key -- npx @spain-ai-kit/aemet-mcp-server

Try it

Once configured, ask your AI assistant things like:

• 💬 "What is the current CPI in Spain?"

• 💬 "Search Spanish law about data protection and summarise the most recent changes"

• 💬 "Show me employment statistics for Valencia province over the last 5 years"

• 💬 "What does the foreigners law say about residence permits for UK nationals?"

• 💬 "What property is at Calle Gran Vía 1, Madrid? Get me the cadastral reference"

• 💬 "Is there a weather alert for Andalucía today?"

• 💬 "What's the UV index in Málaga and should I put sunscreen on the kids?"

• 💬 "Find properties within 100 metres of these coordinates"

For detailed usage examples, tips, and troubleshooting, see the User Guide.
