Overview

AI-generated overview

Lets an assistant check Korean business registrations, addresses, DART corporation data, apartment sale prices and current statutes.

What you can do
Offers eight Korean data-checking tools: look up National Tax Service business registration status and taxation type, optionally verifying the representative name and opening date; search and normalize road-name and lot-number addresses; find Financial Supervisory Service DART corporation codes by name and fetch company profiles; query Ministry of Land apartment sale transaction prices by district code and contract month; and search current statutes from the Ministry of Government Legislation. Two free tools report the API key's credit balance and per-tool pricing.
When to use it
Use it when an assistant must check Korean company or business registration, normalize Korean addresses, look up DART corporation data, apartment sale prices or current statutes. Suited to due-diligence work involving the Korean market, real estate or compliance.
Requirements
Needs the remote endpoint and a Bearer API key in the Authorization header; a key is requested by email from the service. Tools are billed in credits, so the account needs a sufficient balance.
Before you install
Each call spends credits, some tools 2 to 3 per call, so check balance and pricing first. Queries are sent to a third-party service, and the API key must be supplied and kept safe.

Installation

In SourceWeft

  1. Open Kr Groundtruth in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.ChloePark85%2Fkr-groundtruth/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
