An MCP server that provides KOSPI/KOSDAQ stock data from KRX Data Marketplace.

## What's New in v0.3.0

Since December 27, 2024, KRX Data Marketplace requires **Kakao/Naver login** for data access. This version implements:

- **Direct KRX API integration** with Kakao OAuth login
- **Playwright-based headless browser** for authentication
- **Automatic session management** with 4-hour timeout and auto re-login
- **No more pykrx dependency** for core functionality

## Features

- Lookup KOSPI/KOSDAQ ticker symbols and names
- Retrieve OHLCV (Open/High/Low/Close/Volume) data for stocks
- Retrieve market capitalization data
- Retrieve fundamental data (PER/PBR/Dividend Yield)
- Retrieve trading volume by investor type (institutional, foreign, individual)
- Retrieve index OHLCV data (KOSPI, KOSDAQ indices)

## Requirements

- Python 3.10+
- Kakao account (2FA must be disabled)
- Playwright Chromium browser

## Environment Variables

```bash
# Required: Kakao login credentials
KAKAO_ID=your_kakao_id
KAKAO_PW=your_kakao_password
```

> **Important**: Your Kakao account must have 2-step verification (2FA) disabled.
> On first login, you may need to approve the login request via KakaoTalk.

## Installation

## Troubleshooting

### "KakaoTalk login notification" popup

On first login, Kakao may require approval via KakaoTalk:
1. Run with `headless=False` to see the browser
2. Approve the login in KakaoTalk
3. Cookies will be saved for future sessions

### 401 Unauthorized / Session Expired

Session expires after ~4 hours. The server auto-renews, but if it fails:
1. Delete `~/.krx_session.json`
2. Restart the server

### Linux Headless Environment

```bash
# Install required packages on Ubuntu/Debian
apt-get install -y libnss3 libatk1.0-0 libatk-bridge2.0-0 libcups2 libdrm2 \
    libxkbcommon0 libxcomposite1 libxdamage1 libxfixes3 libxrandr2 libgbm1 libasound2
