Track Market Sentiment in Claude Desktop

The `get_sentiment_analysis` tool feeds live, scored financial news directly to your desktop client. When you ask Claude Desktop to evaluate a stock, it pulls the latest articles and parses the sentiment scores to spot shifting market moods before they hit your charts. Skip the noise and combine this with `get_trending_news` to see which tickers are dominating the conversation right now. Instead of hunting through terminal tabs, you get a clean summary of what is driving the market directly in your chat.

Live Exchange Tracking via MCP Server

This MCP Server exposes `get_stock_market_status` to let your agent check if global exchanges are open, closed, or in pre-market hours. Claude Desktop uses this status data to time your analytical queries and avoid stale off-hours assumptions. It also calls `get_indices` to pull broad benchmark performance alongside your stock-specific queries. This gives your local agent the macro context needed to verify if a stock's movement is an outlier or just following the broader market trend.

Map Symbols and Industries Instantly via MCP

The `get_symbols` tool maps messy company names to exact stock tickers inside Claude Desktop. Your agent uses these tools to resolve ambiguous text in news articles and tie them to verified financial entities. When exploring a sector, `list_industries` and `search_exchanges` let you filter news by specific market segments. Claude Desktop processes these structured lists to build focused watchlists based on raw market intelligence.
