Ukrainian Statistics MCP Server

🇺🇦 Українська версія

A Model Context Protocol (MCP) server that provides AI models with seamless access to Ukrainian statistical data from the State Statistics Service of Ukraine (Державна служба статистики України) via their SDMX API v3.

Features

• 🇺🇦 Access to official Ukrainian government statistics
• 📊 Support for multiple statistical domains (energy, demographics, trade, etc.)
• 🌐 Bilingual support (Ukrainian and English)
• 🔍 Flexible data filtering and querying
• 📈 Comprehensive metadata exploration (dataflows, structures, codelists)

Installation

Method 1: Quick Install Using Install Scripts

The easiest way to install locally is using the provided install scripts. These scripts automatically install dependencies, build the project, and make the command globally available.

Windows (PowerShell):

.\install.ps1

Windows (Command Prompt):

install.bat

Linux/macOS:

chmod +x install.sh
./install.sh

The install scripts will:

1. ✅ Check for Node.js (requires version 18 or higher)
2. 📦 Install all dependencies
3. 🔨 Build the project
4. 🔗 Link the command globally (makes ukrainian-stats-mcp available system-wide)

After running the install script, add to Claude Desktop configuration:

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

{
  "mcpServers": {
    "ukrainian-stats": {
      "command": "ukrainian-stats-mcp"
    }
  }
}

Then restart Claude Desktop and you're ready to use the server!

Note: On Linux/macOS, if you encounter permission issues, you may need to run sudo ./install.sh or configure npm to use a user directory (the script will provide instructions).

Method 2: Install from GitHub

1. Install globally via npm from GitHub:

npm install -g git+https://github.com/VladyslavMykhailyshyn/ukrainian-stats-mcp-server.git

2. Add to Claude Desktop configuration:

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

{
  "mcpServers": {
    "ukrainian-stats": {
      "command": "ukrainian-stats-mcp"
    }
  }
}

3. Restart Claude Desktop - The server will be ready to use!

Method 3: Local Development Installation

1. Clone the repository:

git clone https://github.com/VladyslavMykhailyshyn/ukrainian-stats-mcp-server.git
cd ukrainian-stats-mcp-server

2. Install dependencies:

npm install

3. Build the project:

npm run build

4. Add to Claude Desktop configuration (use absolute path):

{
  "mcpServers": {
    "ukrainian-stats": {
      "command": "node",
      "args": ["/absolute/path/to/ukrainian-stats-mcp-server/build/index.js"]
    }
  }
}

Common Usage Workflows

Workflow 1: Exploring a New Dataset

1. List dataflows to find interesting datasets

   List all dataflows

2. Get dataflow details to understand what the dataset contains

   Get dataflow DF_SUPPLY_USE_ENERGY

3. Get data structure to see dimensions and attributes

   Get data structure DSD_SUPPLY_USE_ENERGY

4. Get codelists to see allowed values for dimensions

   Get codelist CL_SUPPLY_USE_ENERGY_INDICATOR

5. Retrieve data with appropriate filters

   Get data from DF_SUPPLY_USE_ENERGY for 2020-2023

Workflow 2: Quick Data Retrieval

If you already know the dataflow ID:

Get energy supply and use data from DF_SUPPLY_USE_ENERGY for the last 3 years

The AI will use the appropriate tools to fetch the data.

Data Format

All responses are returned in JSON format, converted from the original SDMX XML responses. The JSON structure follows the SDMX standard with attributes prefixed with @_.

Troubleshooting

Server not appearing in Claude Desktop

1. Check that the path in claude_desktop_config.json is correct
2. Ensure you've built the project with npm run build
3. Restart Claude Desktop
4. Check Claude Desktop logs for errors

API Request Failures

• The Ukrainian Statistics API may have rate limits
• Some datasets might be temporarily unavailable
• Network connectivity to stat.gov.ua is required

XML Parsing Errors

If you encounter XML parsing errors, the API response format may have changed. Please report this as an issue.
