Signal Scanner is a rule-based stock and cryptocurrency screener that pulls market data via yfinance, computes technical indicators, and alerts you when symbols match your custom rules. It works on the command line, via Telegram push, or as an MCP tool for Claude Desktop/Claude Code.
Install the Python dependencies (pip install -r requirements.txt), then define a watchlist (plain text) and a ruleset (YAML). Run a one‑shot scan with python -m signal_scanner, use --watch for continuous polling, add --notify for Telegram alerts, or configure it as an MCP server in Claude Desktop’s JSON config. Clients only ever edit watchlist.txt and rules.yaml—the engine code stays untouched.
