This package requires uv for installation and execution.

To install KOSPI/KOSDAQ Stock Data Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @dragon1086/kospi-kosdaq-stock-server --client claude

# Create and activate a virtual environment
uv venv .venv
source .venv/bin/activate  # On Unix/macOS
# .venv\Scripts\activate   # On Windows

# Install the package
uv pip install kospi-kosdaq-stock-server

After installing the package, you need to configure the MCP server in your claude_desktop_config.json file.

1. Locate the configuration file:

   • On macOS, the file is typically located at: /Users/username/Library/Application Support/Claude/claude_desktop_config.json
   • On Windows, the file is typically located at: %APPDATA%/Claude/claude_desktop_config.json

2. Add the server configuration: Open the claude_desktop_config.json file and add a new entry to the mcpServers object:

{
    "mcpServers": {
        "kospi-kosdaq": {
            "command": "uvx",
            "args": ["kospi_kosdaq_stock_server"]
        }
    }
}

Configuration Details:

• command: Use uvx to take advantage of uv's isolation and dependency management
• args: Only the package name is needed since the entry point is defined in the package
• No additional environment variables are required

3. Restart Claude: After saving the changes to claude_desktop_config.json, restart Claude for the changes to take effect.

After configuring the server, you can use it in Claude like this:
