MCP Server for Statistics Denmark

A hobbyist project to create an MCP (Model Context Protocol) Server that wraps the Statistics Denmark (Danmarks Statistik) StatBank API, giving AI assistants direct access to Danish statistical data — including taxes, income, population, employment, and more.

Features

| Tool | Description | |---|---| | list_subjects | Browse the subject hierarchy (e.g. Taxes, Economy, Population) | | list_tables | List all available data tables, optionally filtered by subject | | search_tables | Search tables by keyword (e.g. "tax", "VAT", "income") | | get_table_metadata | Get variables and filter values for a specific table | | get_table_data | Fetch actual data from a table with variable filters |

All data is returned in English. No API key required — the DST StatBank API is free and open.

Requirements

Node.js v18 or higher
npm v8 or higher

Installation

# Clone or copy the project
cd mcp-statistics-denmark

# Install dependencies
npm install

# Build TypeScript
npm run build

Usage with Claude Desktop

Add the following to your claude_desktop_config.json:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "dst-statistics-denmark": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-statistics-denmark/dist/index.js"]
    }
  }
}

Then restart Claude Desktop. You should see the 5 DST tools available.

Usage with Claude Code (CLI)

claude mcp add dst-statistics-denmark -- node /absolute/path/to/mcp-statistics-denmark/dist/index.js

Example Queries

Once connected, you can ask Claude things like:

"Search for Danish tax tables"
"What variables are available in table SKAT10?"
"Get income tax data for all years from table INDKP101"
"List all subjects in the Statistics Denmark StatBank"
"Show me VAT revenue data from Denmark"

Typical Workflow

Discover — Use search_tables or list_subjects → list_tables to find the right table ID
Inspect — Use get_table_metadata to see what variables and filter values are available
Fetch — Use get_table_data with the variable codes and value codes from step 2

Example

search_tables("tax")
→ finds table "SKAT10" - "Tax assessments by type"

get_table_metadata("SKAT10")
→ shows variables: SKATTYPE (tax type), Tid (time period), OMRÅDE (region)
→ shows valid values for each variable

get_table_data("SKAT10", { "Tid": ["*"], "SKATTYPE": ["1"], "OMRÅDE": ["000"] })
→ returns rows of actual tax data
