What is tradingview-mcp-server CLAUDE.md?

A development guide for an unofficial TradingView market-screening server and command-line tool. It lets AI tools or terminal users screen stocks, currencies, cryptocurrencies, and exchange-traded funds through TradingView data.

Developing and testing TradingView screening tools, including the TypeScript build, automated tests, local server, and command-line entry point.

It gives contributors the commands and architecture needed to build, test, run, and reload the server correctly. It also explains that the command line and MCP server share their core logic.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01777	$0.01777
Opus 5.5	$0.00711	$0.00711
Sonnet 5.5	$0.00355	$0.00355

Security

Grade A, and why

tradingview-mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

TradingView MCP Server is an unofficial Model Context Protocol server and CLI tool that provides access to TradingView's market screener API. It enables AI-powered stock, forex, crypto, and ETF screening through Claude Desktop, Claude Code, or the standalone tradingview-cli command.

Build and Development Commands

npm install          # Install dependencies
npm run build        # Compile TypeScript to dist/
npm test             # Run all tests
npm run test:watch   # Run tests in watch mode
npm run dev          # Run MCP server directly with tsx (no build step)
npm run dev:cli      # Run CLI directly with tsx (no build step)

Running a single test file

npm test -- fields.test.ts

Development workflow

For local development, use npm run dev which runs TypeScript directly via tsx without requiring a build step. After making changes:

Restart Claude to reload the MCP server (no hot-reload)
Test via Claude's MCP integration

Architecture

Dual Entry Points

The package has two entry points sharing all core logic:

MCP Server — src/index.ts Creates the MCP server, registers tools and resources, handles tool calls via stdio. Initializes core components:

TradingViewClient - API client
Cache - Response caching (configurable TTL)
RateLimiter - Request throttling (configurable RPM)
ScreenTool, FieldsTool, PresetsTool - Tool implementations

CLI — src/cli.ts Standalone CLI using Node's built-in util.parseArgs. Reuses the same tool classes. Output formats: JSON (default), CSV, table. No cache.startCleanup() (CLI is short-lived).

CLI Helpers (src/cli/)

parseArgs.ts - Option configs, input builders, preset merging
formatters.ts - JSON/CSV/table output formatters
help.ts - Help text for all commands

Core Components

API Layer (src/api/)

client.ts - HTTP client for TradingView scanner API endpoints (/global/scan, /forex/scan, /crypto/scan)
search.ts - Symbol search via TradingView symbol-search v3 endpoint
metainfo.ts - Market metainfo via scanner /metainfo endpoint
ta.ts - Technical analysis summary and ranking via scanner Recommend.All/Other/MA fields
types.ts - TypeScript interfaces for API requests/responses

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
