How to Set Up and Use Data Go
The data-go-mcp-servers project provides a collection of Python MCP servers that expose APIs from Korea's public data portal (data.go.kr), making government datasets accessible through AI assistants like Claude. It covers six domains: National Pension Service business enrollment records, National Tax Service business verification, Public Procurement Service bid and contract data, Financial Supervisory Service corporate financials, presidential speeches, and MSDS chemical safety data. Korean developers and analysts use it to verify business registrations, research procurement contracts, look up chemical hazard information, and query corporate financials entirely in natural language.
Prerequisites
- Python 3.10+ and uv (recommended) or pip
- An API key from data.go.kr — register at https://www.data.go.kr and apply for the specific API you need
- Claude Desktop or another MCP-compatible client
Register on data.go.kr and obtain an API key
Create an account at https://www.data.go.kr, find the API service you need (e.g. NTS business verification), and submit an application. You will receive an API_KEY upon approval — this is required for all six server packages.
Install uv (recommended)
The project recommends using uv for running the Python packages, as it handles virtual environments automatically.
curl -LsSf https://astral.sh/uv/install.sh | shChoose which API package to install
Install only the package(s) relevant to your use case. Each package is independent.
# Business verification (most commonly needed)
uv pip install data-go-mcp.nts-business-verification
# Other available packages:
# uv pip install data-go-mcp.nps-business-enrollment
# uv pip install data-go-mcp.pps-narajangteo
# uv pip install data-go-mcp.fsc-financial-info
# uv pip install data-go-mcp.presidential-speeches
# uv pip install data-go-mcp.msds-chemical-infoAdd the server to Claude Desktop configuration
Add the desired package to your Claude Desktop config using uvx. Set your data.go.kr API key in the env block.

"command": "uvx",
"args": ["data-go-mcp.nts-business-verification@latest"],
"env": {
"API_KEY": "your-data-go-kr-api-key"
}
}
}
}Add multiple packages if needed
You can register multiple data-go-mcp servers in one config file. Each gets its own entry and shares the same API_KEY.

"mcpServers": {
"nts-business-verification": {
"command": "uvx",
"args": ["data-go-mcp.nts-business-verification@latest"],
"env": { "API_KEY": "your-data-go-kr-api-key" }
},

"command": "uvx",
"args": ["data-go-mcp.nps-business-enrollment@latest"],
"env": { "API_KEY": "your-data-go-kr-api-key" }
}
}
}Restart Claude Desktop and test a query
Restart Claude Desktop and ask it to verify a business registration number or search for procurement contracts to confirm the server is working.

Example prompts for querying Korean public data through Claude.
- "Verify business registration number 123-45-67890 registered under Hong Gildong"
- "Check the current status (active/suspended/closed) for business numbers 123-45-67890 and 098-76-54321"
- "Find workplaces enrolled in the National Pension Service in Seoul's Gangnam district"
- "Search for recent public procurement bids in the construction sector from Narajangteo"
- "Look up the MSDS safety data sheet for ethanol"Troubleshooting Data Go
API returns an error about an invalid or unauthorized key
Confirm the API key from data.go.kr is correct and that you have been approved for the specific API (each service requires a separate application). Check the approval status in your data.go.kr account dashboard.
uvx command not found
Install uv first: `curl -LsSf https://astral.sh/uv/install.sh | sh` and restart your terminal. uvx is bundled with uv. Alternatively use `pip install data-go-mcp.<package-name>` and run with python directly.
Batch validation times out with large lists
The NTS batch_validate_businesses tool supports up to 100 registrations per call. Split larger lists into batches of 100 and make multiple requests.
