  Core handler function that retrieves the 10 most recent news articles for the given stock symbol using yfinance, computes sentiment polarity for each article title via the analyze_sentiment helper (FinBERT model), averages the polarities, classifies overall sentiment as BULLISH, BEARISH, or NEUTRAL based on thresholds, and returns a formatted summary string.

  Registers get_symbol_sentiment (along with related news tools) with the MCP server using the register_tools helper function, which applies the @mcp.tool() decorator to expose it as an MCP tool.

  Helper function called by get_symbol_sentiment to analyze sentiment of individual news titles. Posts text to a Modal-hosted FinBERT endpoint, maps positive/negative/neutral labels and scores to a polarity value (-1 to 1), and returns a dict with polarity, classification, and model info.
