Korean Patent

You can use the Korean Patent MCP Server to search and analyze Korean patents through natural language queries. It connects to the KIPRIS Plus Open API and exposes tools that let you search patents by applicant, retrieve detailed patent information, and find patents that cite a given patent. This enables AI assistants to understand and work with Korean patent data more effectively.

How to use

You interact with the Korean Patent MCP Server through an MCP client. Use natural language prompts to perform common tasks such as searching for patents by applicant name, obtaining detailed information for a specific application number, or discovering patents that cite a particular patent. The server exposes three core tools that cover these capabilities: kipris_search_patents, kipris_get_patent_detail, and kipris_get_citing_patents. When querying, you can phrase requests like “Show me patents filed by Samsung Electronics” or “Tell me the details for patent application number 1020200123456” or “List patents that cite application 1020180056789.” These tools return results in a readable format by default, with an option to request JSON if you need structured data for further processing.

How to install

Install the MCP server using one of the supported installation methods, then run the MCP server locally and connect your MCP client to it. The setup requires a KIPRIS Plus Open API key to access the data.

# Method 1: Smithery (recommended)
npx -y @smithery/cli install korean-patent-mcp --client claude

# Method 2: uv (local installation)
uv pip install git+https://github.com/Tech-curator/korean-patent-mcp.git

Configuration and runtime

Set your API key for KIPRIS to authorize API calls. You can export the key as an environment variable or include it in the MCP client configuration.

export KIPRIS_API_KEY="your_api_key_here"

{
  "mcpServers": {
    "korean-patent": {
      "command": "uv",
      "args": ["run", "korean-patent-mcp"],
      "env": {
        "KIPRIS_API_KEY": "your_api_key_here"
      }
    }
  }
}

Connecting your MCP client

Use the standard MCP client configuration to connect to the local server. The server runs as a stdio process with the uv command, so your client should invoke uv with the appropriate run command and pass any required environment variables, including the KIPRIS API key.
