Implementation Reference

• src/mcp_yahoo_finance/server.py:190-198 (handler)

  The core implementation of the 'get_news' tool handler in the YahooFinance class. It creates a yfinance Ticker for the symbol and returns the news as formatted JSON.

  def get_news(self, symbol: str) -> str:
      """Get news for a given stock symbol.
  
      Args:
          symbol (str): Stock symbol in Yahoo Finance format.
      """
      stock = Ticker(ticker=symbol, session=self.session)
      return json.dumps(stock.news, indent=2)

• src/mcp_yahoo_finance/server.py:204-218 (registration)

  Registration of the 'get_news' tool (line with generate_tool(yf.get_news)) in the MCP Server's list_tools method. The generate_tool utility auto-generates the tool schema from the function's signature and docstring.

  @server.list_tools()
  async def list_tools() -> list[Tool]:
      return [            
          generate_tool(yf.cmd_run),
          generate_tool(yf.get_recommendations),
          generate_tool(yf.get_news),
          generate_tool(yf.get_current_stock_price),
          generate_tool(yf.get_stock_price_by_date),
          generate_tool(yf.get_stock_price_date_range),
          generate_tool(yf.get_historical_stock_prices),
          generate_tool(yf.get_dividends),
          generate_tool(yf.get_income_statement),
          generate_tool(yf.get_cashflow),
          generate_tool(yf.get_earning_dates),
      ]

• src/mcp_yahoo_finance/server.py:247-249 (handler)

  Dispatch handler in the MCP Server's call_tool method that executes the get_news tool by calling yf.get_news with arguments and wrapping the result in TextContent.

  case "get_news":
      price = yf.get_news(**args)
      return [TextContent(type="text", text=price)]
