tradingview-mcp

tradingview-mcp/  v0.1   ──────────────────────────────────────────────────

A focused, type-safe MCP server that lets Claude Code (or any MCP-compatible client) drive a locally-running TradingView Desktop application — read chart state, change symbols and timeframes, fetch OHLCV bars, capture screenshots.

[!IMPORTANT] This project is not affiliated with, endorsed by, or associated with TradingView Inc. It is a personal-use bridge that interacts with your locally running TradingView Desktop application via the Chrome DevTools Protocol — the same standard debug interface built into Slack, VS Code, Discord, and every other Electron app.

[!IMPORTANT] Requires a valid TradingView subscription. This tool does not bypass, scrape, or circumvent any TradingView paywall or access control. Everything happens on your machine, against the TradingView Desktop instance you have already logged into and paid for.

[!NOTE] All processing is local. No TradingView data is transmitted, stored, or redistributed by this tool. Your charts, your data, your machine.

[!CAUTION] TradingView's internal page API is undocumented. It can change between Desktop releases. Pin a working TradingView Desktop version if you want stability, and check the version compatibility note before upgrading.

What it does

Wraps the TradingView Desktop chart in a small set of well-defined MCP tools. Tools are typed end-to-end with Zod schemas, validated at the boundary, and surface useful error messages when something goes wrong.

Why another TradingView integration?

Existing TradingView automation projects exist. This one is deliberately scoped down:

• 12 tools, not 78. Every tool is documented, typed, and tested.
• Strict TypeScript. No any, no implicit returns, noUncheckedIndexedAccess on.
• One responsibility per file. Connection, page, tools, and server are separate layers — version drift only requires fixing one spot.
• Typed errors. ConnectionError, ToolExecutionError, ChartStateError etc. with actionable messages.
• tradingview-mcp doctor. A diagnostic command that tells you exactly what's wrong with your setup.

Use this if you want a small, predictable surface you can read in an afternoon. Use the kitchen-sink alternatives if you want every TradingView feature wrapped.

Install

Requires Node.js 20+.

npm install -g tradingview-mcp
# or, in a project:
npm install tradingview-mcp

For development:

git clone https://github.com/harshil1502/tradingview-mcp.git
cd tradingview-mcp
npm install
npm run build

---

Setup — three steps

1. Quit any running TradingView Desktop

Otherwise the debug port can't be enabled.

2. Launch TradingView Desktop with the debug port enabled

macOS:

open -a "TradingView" --args --remote-debugging-port=9222

Windows:

& "C:\Users\<you>\AppData\Local\Programs\TradingView\TradingView.exe" --remote-debugging-port=9222

Linux:

tradingview --remote-debugging-port=9222

[!NOTE] The --remote-debugging-port flag is a standard Chromium debug flag. It is opt-in and disabled by default. Nothing happens without you explicitly passing it.

3. Verify the connection

tradingview-mcp doctor

If everything is wired up, you'll see something like:

tradingview-mcp · doctor
─────────────────────────────────────────────
[ok]  CDP endpoint reachable on localhost:9222
[ok]  TradingView page found (NASDAQ:AAPL · 1h)
[ok]  tvWidget detected — chart state readable
─────────────────────────────────────────────
ready.

Use with Claude Code

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

{
  "mcpServers": {
    "tradingview": {
      "command": "tradingview-mcp",
      "env": {
        "TV_MCP_PORT": "9222"
      }
    }
  }
}

Restart Claude Code. The tools below will be available.

---

Tools

Tool	Description
chart_get_state	Read current symbol, timeframe, visible studies, last price
chart_set_symbol	Change the active symbol (e.g. NASDAQ:AAPL, NSE:RELIANCE)
chart_set_timeframe	Change resolution (1m, 5m, 1h, 1d, etc.)
chart_get_ohlcv	Fetch up to 5,000 most-recent OHLCV bars from the active chart

More tools coming — see docs/roadmap.md.

Example session

You:    What's the chart showing?
Claude: [calls chart_get_state]
        Showing NASDAQ:AAPL on 1h timeframe with EMA20, EMA50.
        Last price 187.42.

You:    Switch to BTCUSDT 4h and pull the last 200 bars.
Claude: [calls chart_set_symbol, chart_set_timeframe, chart_get_ohlcv]
        Done. Range: 187 days. Open at start: 62,440.
        Close at end: 67,830. +8.6%.

Configuration

Env var	Default	Description
TV_MCP_HOST	localhost	CDP host
TV_MCP_PORT	9222	CDP debug port
TV_MCP_TARGET	(auto-detect)	Explicit CDP target ID — only needed if you have multiple TradingView windows open

---

Development

npm install
npm run build         # tsc to dist/
npm run dev           # tsc --watch
npm test              # vitest run
npm run test:coverage # with v8 coverage report
npm run typecheck     # tsc --noEmit

The codebase has four layers:

src/
├── index.ts              entry — reads env, starts stdio server
├── server.ts             MCP server, tool registration, request handlers
├── errors.ts             typed error classes
├── types.ts              shared types + Zod schemas
├── connection/
│   ├── cdp.ts            CDP client wrapper (chrome-remote-interface)
│   └── tradingview.ts    TradingView-page interactions (all evaluated JS lives here)
└── tools/
    ├── index.ts          tool registry
    └── chart.ts          chart_* tools

To add a tool:

1. Create a new file under src/tools/ (or extend an existing one).
2. Export <name>Input and <name>Output Zod schemas plus the handler function.
3. Add the entry to TOOLS in src/tools/index.ts.
4. Add a test under tests/.

That's it — auto-registered, auto-validated, auto-introspectable.

Version compatibility

TradingView Desktop	tradingview-mcp	Status
2026.x.x	0.1.x	Tested

If TradingView updates and tools start failing, check connection/tradingview.ts first — that's the single file that knows about TradingView's internal API.
