BullRun – free global stock screener with an MCP server

- **BullRun** is a free, web-based stock screener (bull-run.org) that lets users filter global equities by fundamentals (e.g., P/E ratio, revenue growth) and technical indicators (e.g., moving averages, RSI). Unlike most free screeners, which cover only US markets or charge for global data, BullRun includes exchanges in Europe, Asia, and emerging markets. - **MCP (Model Context Protocol)** is an open standard developed by Anthropic (the company behind Claude) that allows AI assistants to call external tools and APIs. BullRun provides an MCP server, meaning you can connect an AI assistant directly to the screener — the AI can query stocks, apply filters, and return results without the user visiting the website. - **Why it matters**: Combining a free, global screener with an MCP server is unusual. It lets AI-powered coding or research agents (like Claude, Cursor, or custom bots) perform live financial screening on demand, bypassing the usual paywalls and API limits of mainstream financial data providers.
