tradingview-mcp

A Model Context Protocol (MCP) server that gives Claude — or any MCP-compatible client — market data from TradingView, with automatic fallback to a licensed provider when TradingView fails.

Features

• 5 tools: symbol search, live quotes, OHLCV history, technical indicators, backend health check

• Global coverage — equities, crypto, and forex across NASDAQ, NYSE, HKEX, SGX, Binance, and more, addressed by ticker or company name

• Automatic fallback to Twelve Data / Finnhub when TradingView's undocumented endpoints fail or rate-limit

• Freshness labeling on every result — never presents a delayed price as live

• Hardened input validation — bounded array sizes, whitelisted indicator names, sanitized third-party text (see Security)

Read this first

TradingView has no public market-data API. What they publish is the Charting Library (you supply your own datafeed) and embeddable widgets — there is no documented endpoint you can key into.

This server therefore talks to two undocumented TradingView endpoints that their own web app uses:

That means:

• It is against TradingView's Terms of Service to redistribute this data. Treat this as a personal analysis tool. Do not resell, republish, or build a product on it.

• It will break without warning when TradingView changes their wire format. Run npm run health when something stops working — it tells you which backend died.

• Unauthenticated data is delayed for most equities. See below.

Data freshness — the part that matters

Every quote carries a freshness field, because "live" is not what you get by default:

Real-time equity quotes require a paid TradingView subscription and exchange data agreements, which this unauthenticated path cannot access. Never present a delayed price as live — the server tells the model this in its instructions, and every tool result repeats it per symbol.

Install

Requires Node.js 20 or newer.

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

Verify all backends are reachable:

npm run health

(Optional) To enable the licensed-provider fallback, get a free API key from Twelve Data and/or Finnhub. .env.example documents the variable names, but note the server reads them as regular process environment variables — there's no dotenv loader, so a .env file by itself does nothing. Either export the variable in your shell before running the server, or set it in the env block of your MCP client config (shown below).

Register with your MCP client

Every MCP client reads the same two things: the command to run (node) and the absolute path to src/index.js inside wherever you cloned this repo. Get that path by running pwd (macOS/Linux) or cd with no arguments (Windows) inside the tradingview-mcp folder.

Claude Code

claude mcp add tradingview --scope user -- node /absolute/path/to/tradingview-mcp/src/index.js

On Windows, use forward slashes in the path:

claude mcp add tradingview --scope user -- node "C:/path/to/tradingview-mcp/src/index.js"

Claude Desktop, Cursor, VS Code, and other JSON-config clients

Add this block to the client's MCP config file — for Claude Desktop that's claude_desktop_config.json (~/Library/Application Support/Claude/ on macOS, %APPDATA%\Claude\ on Windows); Cursor (.cursor/mcp.json) and VS Code (mcp.json in settings) use the same shape under their own filenames:

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

Restart your MCP client after registering. Run tv_health (or npm run health from the repo) to confirm the server can reach TradingView.

Tools

tv_search_symbol

Resolve a ticker, company name, or ISIN to fully-qualified EXCHANGE:SYMBOL tickers.

tv_search_symbol { "query": "Tencent", "limit": 3 }
-> HKEX:700 | Tencent Holdings Ltd

tv_quote

Price, change, volume, market cap, P/E for up to 50 instruments in one call. Accepts bare tickers (AAPL) or qualified ones (BINANCE:BTCUSDT, HKEX:700, FX:EURUSD).

tv_quote { "symbols": ["AAPL", "BINANCE:BTCUSDT", "HKEX:700"] }
-> NASDAQ:AAPL   309.90  -0.14%  delayed by ~15 min
   BINANCE:BTCUSDT 78819.33 +0.40%  real-time
   HKEX:700       445.40  +0.77%  delayed by ~15 min

tv_history

OHLCV candles, oldest first, with epoch-seconds and ISO (UTC) timestamps.

tv_history { "symbol": "AAPL", "interval": "1D", "bars": 200 }

Intervals: 1m 3m 5m 15m 30m 45m 1h 2h 4h 1D 1W 1M.

Note: daily candles are stamped at the session open in UTC (a US daily bar reads 13:30:00Z), not midnight. The most recent candle may still be forming.

tv_indicators

TradingView's precomputed indicator values plus its Strong Buy…Strong Sell technical rating, at any supported timeframe. TradingView-only — the fallback provider does not compute indicators.

tv_indicators { "symbols": ["AAPL", "NVDA"], "interval": "1D" }
-> NASDAQ:AAPL  RSI 47.8  SMA50 310.88  rating Neutral
   NASDAQ:NVDA  RSI 49.6  SMA50 207.81  rating Buy

Supported: RSI RSI7 MACD.macd MACD.signal Stoch.K Stoch.D Stoch.RSI.K SMA5…SMA200 EMA5…EMA200 ADX ADX+DI ADX-DI ATR CCI20 Mom AO UO ROC W.R BB.upper BB.lower BBPower VWMA HullMA9 Ichimoku.BLine P.SAR Pivot.M.Classic.S1 Pivot.M.Classic.R1 Recommend.All Recommend.MA Recommend.Other

An unrecognised indicator name is rejected rather than passed through, because TradingView silently returns null for typos — which is indistinguishable from "no data".

tv_health

Probes every backend and reports which are answering, with latencies. Run this first when something misbehaves.

The fallback layer

When a TradingView endpoint fails or rate-limits, tv_quote and tv_history retry against a documented provider with real terms of service. Configure via environment variables:

Both have free tiers. Without a key the server still works — you just lose the safety net, and TradingView failures surface as errors.

Results always name their origin in a source field (tradingview:scanner, tradingview:ws, twelvedata, finnhub) so you can tell where a number came from.

Tests

npm test

Runs smoke.mjs, fallback.mjs, failover.mjs, and security-regression.mjs in sequence. smoke.mjs hits the live endpoints, so it needs a network connection and will show current prices.

Security

Trust boundary. This is a stdio MCP server: it has no network listener (confirmed - the only transport wired up is StdioServerTransport, and the only WebSocket use is an outbound client to data.tradingview.com). There is no login, session, or API-key gate on the server itself, and none is meaningful here: whatever process can write to this server's stdin already has the same privileges any caller would have, since there's no privilege differentiation between callers. The actual security boundary is "who can spawn this process" - i.e. your MCP host / IDE integration - not an authentication layer inside this repo.

Treat tool output as data, never as instructions. tv_search_symbol and tv_quote return free-text fields (description, name, exchange) sourced from TradingView's third-party symbol database. This server strips HTML tags, control characters, and zero-width/bidi-override Unicode from those fields and caps them at 200 characters (src/symbols.js), but that only shrinks the payload - it does not make the content trustworthy. Any agent consuming this server's output should treat every returned field as untrusted data, the same way it would treat the body of a fetched web page, and never follow instruction-like phrasing found inside a company name or instrument description.

Input validation. All tool arguments are bounded with zod: array lengths (symbols, indicators), numeric ranges (bars), string length (search query), and an enum (interval). The market scanner slug is restricted to [a-z0-9_-] because it is interpolated into a URL path (scanner.tradingview.com/${market}/scan) - this rejects path traversal, query/fragment injection, and CRLF, even though (verified by testing) the hardcoded hostname made none of those exploitable as SSRF in the first place.

No shell/eval/filesystem access. Nothing in src/ calls a shell, eval, Function, or the filesystem - grep for child_process|exec\(|eval\(|new Function|readFile|writeFile to confirm after future changes.

Fallback API keys (TWELVEDATA_API_KEY, FINNHUB_API_KEY) are only ever read from environment variables, only ever sent as outbound query parameters to their respective providers, and are never included in error messages, logs, or tool output - error paths only surface HTTP <status>: <truncated body>, never the request URL or key.

This has been through one adversarial review pass (command/code injection, SSRF via the market parameter, prompt-injection surface, credential leakage on fallback failure, input validation bypass, error-message hygiene, and the stdio trust boundary itself). See tests/security-regression.mjs for the checks that came out of it.

Limitations

• Delayed equity data (see above) — this is a hard limit of unauthenticated access.

• No order book, no tick-by-tick trades, no options chains.

• No screening/filtering tool; the scanner client supports filter and sort payloads if you want to add one.

• Indicators have no fallback — if TradingView's scanner is down, tv_indicators fails rather than computing them locally from candles.

• This places no trades and touches no brokerage account. It is read-only market data.
