Implementation Reference

• src/vnstock_mcp/server.py:93-110 (handler)

  The handler function implements the get_company_shareholders tool. It creates a TCBSCompany instance, calls its shareholders() method to fetch data, and returns it as JSON or pandas DataFrame based on output_format. The @server.tool() decorator handles both registration and schema inference from type hints.

  @server.tool()

      symbol: str, output_format: Literal["json", "dataframe"] = "json"
