tradesdontlie/tradingview-mcpPublic

Personal AI assistant for your TradingView Desktop charts. Connects Claude Code to your locally running TradingView app via Chrome DevTools Protocol for AI-assisted chart analysis, Pine Script development, and workflow automation.

This tool does not connect to TradingView's servers, modify any TradingView files, or intercept any network traffic. It communicates exclusively with your locally running TradingView Desktop instance via Chrome DevTools Protocol (CDP) — a standard debugging interface built into all Chromium/Electron applications by Google, including VS Code, Slack, and Discord.

The debug port is disabled by default and must be explicitly enabled by you using a standard Chromium flag (--remote-debugging-port=9222). Nothing happens without that deliberate step.

• Connect to TradingView's servers or APIs
• Store, transmit, or redistribute any market data
• Work without a valid TradingView subscription and installed Desktop app
• Bypass any TradingView paywall or access restriction
• Execute real trades (chart interaction only)
• Work if TradingView changes their internal Electron structure

This project explores an open research question: how can LLM-based agents interact with professional trading interfaces to support human decision-making?

Specifically it investigates:

• How structured tool APIs (MCP) can bridge LLMs and stateful desktop financial applications
• What latency, context, and reliability constraints emerge when an agent operates on live chart data
• How agents handle ambiguous financial UI state (e.g. interpreting Pine Script output, reading indicator tables)
• Whether natural language is an effective interface for chart navigation and Pine Script development
• The failure modes of LLM agents operating in real-time data environments

This is not a trading bot. It is an interface layer that makes a trading application legible to an LLM agent, allowing researchers and developers to study human-AI collaboration in financial workflows.

See RESEARCH.md for open questions, findings, and related work.

• TradingView Desktop app (paid subscription required for real-time data)
• Node.js 18+
• Claude Code with MCP support (for MCP tools) or any terminal (for CLI)
• macOS, Windows, or Linux

Gives your AI assistant eyes and hands on your own chart:

• Pine Script development — write, inject, compile, debug, and iterate on scripts with AI assistance
• Chart navigation — change symbols, timeframes, zoom to dates, add/remove indicators
• Visual analysis — read your chart's indicator values, price levels, and annotations
• Draw on charts — trend lines, horizontal lines, rectangles, text annotations
• Manage alerts — create, list, and delete price alerts
• Replay practice — step through historical bars, practice entries/exits
• Screenshots — capture chart state for AI visual analysis
• Multi-pane layouts — set up 2x2, 3x1, etc. grids with different symbols per pane
• Monitor your chart — stream JSONL from your locally running chart for local monitoring scripts
• CLI access — every MCP tool is also a tv CLI command, pipe-friendly with JSON output
• Launch TradingView — auto-detect and launch with debug mode from any platform

Paste this into Claude Code and it will handle the rest:

Install the TradingView MCP server. Clone https://github.com/tradesdontlie/tradingview-mcp.git, run npm install, add it to my MCP config at ~/.claude/.mcp.json, and launch TradingView with the debug port. Then verify the connection with tv_health_check.

Or follow the manual steps below.

git clone https://github.com/tradesdontlie/tradingview-mcp.git
cd tradingview-mcp
npm install

TradingView Desktop must be running with Chrome DevTools Protocol enabled on port 9222.

Mac:

./scripts/launch_tv_debug_mac.sh

Windows:

scripts\launch_tv_debug.bat

Linux:

./scripts/launch_tv_debug_linux.sh

Or launch manually on any platform:

/path/to/TradingView --remote-debugging-port=9222

Or use the MCP tool (auto-detects your install):

"Use tv_launch to start TradingView in debug mode"

Add to your Claude Code MCP config (~/.claude/.mcp.json or project .mcp.json):

{
  "mcpServers": {
    "tradingview": {
      "command": "node",
      "args": ["/path/to/tradingview-mcp/src/server.js"]
    }
  }
}

Replace /path/to/tradingview-mcp with your actual path.

Ask Claude: "Use tv_health_check to verify TradingView is connected"

Every MCP tool is also accessible as a tv CLI command. All output is JSON for piping with jq.

# Install globally (optional)
npm link

# Or run directly
node src/cli/index.js <command>

tv status                          # check connection
tv quote                           # current price
tv symbol AAPL                     # change symbol
tv ohlcv --summary                 # price summary
tv screenshot -r chart             # capture chart
tv pine compile                    # compile Pine Script
tv pane layout 2x2                 # 4-chart grid
tv pane symbol 1 ES1!              # set pane symbol
tv stream quote | jq '.close'      # monitor price changes

tv status / launch / state / symbol / timeframe / type / info / search
tv quote / ohlcv / values
tv data lines/labels/tables/boxes/strategy/trades/equity/depth/indicator
tv pine get/set/compile/analyze/check/save/new/open/list/errors/console

tv stream quote/bars/values/lines/labels/tables/all
tv ui click/keyboard/hover/scroll/find/eval/type/panel/fullscreen/mouse
tv screenshot / discover / ui-state / range / scroll

The tv stream commands poll your locally running TradingView Desktop instance at regular intervals via Chrome DevTools Protocol on localhost.

No connection is made to TradingView's servers. All data stays on your machine.

tv stream quote                          # price tick monitoring
tv stream bars                           # bar-by-bar updates
tv stream values                         # indicator value monitoring
tv stream lines --filter "NY Levels"     # price level monitoring
tv stream tables --filter Profiler       # table data monitoring
tv stream all                            # all panes at once (multi-symbol)

Claude reads CLAUDE.md automatically when working in this project. It contains a complete decision tree:

Read line.new(), label.new(), table.new(), box.new() output from any visible Pine indicator.

Always use study_filter to target a specific indicator: study_filter: "Profiler".

Tools return compact output by default to minimize context usage. For a typical "analyze my chart" workflow, total context is ~5-10KB instead of ~80KB.

Launch scripts and tv_launch auto-detect TradingView. If auto-detection fails:

The key flag: --remote-debugging-port=9222

# Requires TradingView running with --remote-debugging-port=9222
npm test

29 tests covering: Pine Script static analysis, server-side compilation, and CLI routing.
