# TradingView MCP Server 📈

A **lightweight** Model Context Protocol (MCP) server for fetching TradingView chart snapshots. Uses Playwright for efficient browser automation with persistent sessions and cookie-based authentication.

> **Note**: This uses Playwright because TradingView renders charts client-side with JavaScript/Canvas. There is no pure HTTP API for chart images. This is the lightest possible working solution (~150MB RAM vs ~500MB with Selenium).

## ✨ Features

- 🪶 **Lightweight**: Playwright in headless mode (~150MB vs ~500MB with Selenium)
- 🚀 **Fast**: Persistent browser reuse, 3-5 seconds per chart
- 🔐 **Secure**: Session-based authentication via cookies
- 🎨 **Customizable**: Configure chart dimensions, intervals, and themes
- 🔧 **MCP Compatible**: Works with any MCP-enabled client (Claude Desktop, etc.)
- ♻️ **Efficient**: Reuses browser instances across multiple requests

## 📋 Prerequisites

- Python 3.10 or higher
- A TradingView account (free or paid)
- TradingView session cookies

## 🚀 Installation

### 1. Clone the repository

```bash
git clone https://github.com/yourusername/tradingview-mcp.git
cd tradingview-mcp
```

### 2. Create a virtual environment

```bash
# Windows
python -m venv venv
.\venv\Scripts\activate

# Linux/Mac
python3 -m venv venv
source venv/bin/activate
```

### 3. Install dependencies

```bash
pip install -r requirements.txt

# Install Playwright browsers (one-time setup, ~150MB download)
python -m playwright install chromium
```

### 4. Configure credentials

1. Copy `.env.example` to `.env`:
   ```bash
   # Windows
   copy .env.example .env
   
   # Linux/Mac
   cp .env.example .env
   ```

2. **Get your TradingView session cookies:**
   - Log into [TradingView](https://www.tradingview.com) in your browser
   - Press **F12** to open Developer Tools
   - Go to **Application** tab (Chrome) or **Storage** tab (Firefox)
   - Navigate to **Cookies** > `https://www.tradingview.com`
   - Find and copy these two cookie values:
     - `sessionid` → Copy the entire value
     - `sessionid_sign` → Copy the entire value
   
   > ⚠️ **Important**: Copy the full values including any special characters (slashes, equals signs, etc.). Don't add quotes or extra spaces.

3. Edit `.env` and paste your values:
   ```env
   TRADINGVIEW_SESSION_ID=your_actual_session_id_here
   TRADINGVIEW_SESSION_ID_SIGN=your_actual_session_id_sign_here
   ```
   
   Example (with fake values):
   ```env
   TRADINGVIEW_SESSION_ID=47zlhkbl2weohrhmjgufeg1o24droaod
   TRADINGVIEW_SESSION_ID_SIGN=v3:6S2OD9ta349/yqN0RdCeK3UKxTl/tJr4AOoPRUa0Crk=
   ```

### 5. Test your setup (Optional but recommended)

Create a test file `test.py`:

```python
import asyncio
import sys
from pathlib import Path
sys.path.insert(0, str(Path(__file__).parent / "src"))

from dotenv import load_dotenv
load_dotenv()

from tradingview_mcp.server import get_chart_snapshot

async def test():
    image = await get_chart_snapshot("BINANCE:BTCUSDT", "D", 1200, 600, "dark")
    if image:
        Path("test_chart.png").write_bytes(image)
        print(f"✅ Success! Chart saved to test_chart.png ({len(image)} bytes)")
    else:
        print("❌ Failed to fetch chart")

asyncio.run(test())
```

Run it:
```bash
python test.py
```

If successful, you'll see `test_chart.png` with a Bitcoin chart!

## 🎯 Usage

### Quick Start - Testing Locally

After installation, test the server:

```bash
python src/tradingview_mcp/server.py
```

The server will start and wait for MCP client connections via stdio.

**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`  
**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`  
**Linux**: `~/.config/Claude/claude_desktop_config.json`

**Option 1: Using .env file (Recommended)**
```json
{
  "mcpServers": {
    "tradingview": {
      "command": "python",
      "args": ["C:\\path\\to\\tradingview-mcp\\src\\tradingview_mcp\\server.py"],
      "cwd": "C:\\path\\to\\tradingview-mcp"
    }
  }
}
```

**Option 2: Inline credentials**
```json

| `BINANCE:BTCUSDT` | Bitcoin/USDT on Binance |
| `NASDAQ:AAPL` | Apple Inc. on NASDAQ |
| `NYSE:TSLA` | Tesla Inc. on NYSE |
| `BITSTAMP:BTCUSD` | Bitcoin/USD on Bitstamp |
| `FX:EURUSD` | EUR/USD forex pair |
| `COINBASE:ETHUSD` | Ethereum/USD on Coinbase |

### Finding Symbol Names

1. Go to [TradingView](https://www.tradingview.com)
2. Search for your desired asset
3. Look at the URL or chart title for the format `EXCHANGE:SYMBOL`

## 🔧 Architecture

This MCP server uses **Playwright for lightweight browser automation**:

1. **Authentication**: Session cookies passed to browser context
2. **Chart Generation**: Playwright navigates to TradingView and captures screenshots
3. **Efficiency**: Persistent browser instances reused across requests
4. **MCP Protocol**: Communicates via stdio with MCP clients

**Why Playwright (Not Pure HTTP)?**

- TradingView renders charts client-side with JavaScript/Canvas
- No server-side API exists for chart image generation
- Playwright is lighter than Selenium (~150MB vs ~500MB RAM)
- Headless mode with optimized flags minimizes resource usage
- Browser reuse makes subsequent requests very fast (1-2 seconds)

✅ **This is the lightest possible approach for TradingView charts**

## 🐛 Troubleshooting

### Cookie/Authentication Issues

**Problem**: "Session credentials are not working" or "Invalid session"

**Solutions**:
1. **Check for trailing commas or spaces**: Make sure your `.env` file has no extra characters
   ```env
   # ❌ Wrong (has comma)
   TRADINGVIEW_SESSION_ID=abc123,
   
   # ✅ Correct
   TRADINGVIEW_SESSION_ID=abc123
   ```

2. **Refresh cookies**: Session cookies expire after ~30 days
   - Log out and back into TradingView
   - Get fresh cookies from Developer Tools
   - Update your `.env` file

3. **Check you're logged in**: Make sure you're logged into TradingView when copying cookies

4. **Copy entire value**: Include special characters (=, /, :, etc.)

### Symbol Not Found

**Problem**: "Failed to fetch chart snapshot"

**Solutions**:
1. Use correct format: `EXCHANGE:SYMBOL` (all uppercase)
   - ✅ `BINANCE:BTCUSDT`
   - ❌ `btcusdt` or `binance:btcusdt`

2. Verify symbol exists on TradingView.com

3. Test with a known symbol first: `BINANCE:BTCUSDT` or `NASDAQ:AAPL`

### Timeout Errors

**Problem**: "Timeout exceeded" or slow performance

**Solutions**:
1. Check internet connection and TradingView.com accessibility
2. First request takes longer (5-8s) while browser starts
3. Subsequent requests are faster (3-5s) due to browser reuse
4. If persistent, restart the MCP server

### Playwright Installation Issues

**Problem**: "Playwright not found" or browser download fails

**Solutions**:
```bash
# Reinstall Playwright
pip uninstall playwright
pip install playwright

# Install browsers again
python -m playwright install chromium

# If still failing, install system dependencies (Linux)
sudo playwright install-deps
```

### Claude Desktop Not Recognizing Server

**Problem**: Tools don't appear in Claude Desktop

**Solutions**:
1. Check JSON syntax in config file (use a JSON validator)
2. Use **absolute paths** (not relative)
3. Verify Python path is correct:
   ```bash
   # Windows
   where python
   
   # Mac/Linux
   which python
   ```
4. **Completely restart** Claude Desktop (not just reload)
5. Check Claude logs for errors:
   - Windows: `%APPDATA%\Claude\logs\`
   - Mac: `~/Library/Logs/Claude/`

### Performance Issues

**Problem**: High memory usage or slow responses

**Tips**:
- Memory usage: ~150MB is normal for Playwright
- First chart: 5-8 seconds (browser startup)
- Subsequent charts: 3-5 seconds
- Browser is reused across requests for efficiency
- If memory grows over time, restart the server

## ⚡ Performance

| Metric | Value | Notes |
|--------|-------|-------|
| **Memory Usage** | ~150MB | Playwright headless browser |
| **First Request** | 5-8 seconds | Browser startup + chart load |
| **Subsequent Requests** | 3-5 seconds | Browser reuse (persistent) |
| **Image Size** | 50-200KB | PNG format, varies by dimensions |
| **Browser** | Chromium | ~150MB download (one-time) |

**Comparison with Alternatives:**

| Approach | Memory | Speed | Status |
|----------|--------|-------|--------|
| Pure HTTP | ~50MB | 1-2s | ❌ Impossible (no API exists) |
| Selenium | ~500MB | 10-15s | ⚠️ Works but heavy |
| **Playwright** | **~150MB** | **3-5s** | ✅ **Best option** |

## 🔒 Security Notes

- ⚠️ **Never commit your `.env` file** - it contains your session credentials
- ⚠️ **Don't share your session cookies** - they provide full account access
- ⚠️ **Rotate cookies regularly** - they expire after ~30 days
- ✅ `.env` is in `.gitignore` by default
- ✅ Use environment variables or secure credential management in production
