Implementation Reference
- main.py:431-439 (handler)The handler function implementing the 'fund_nav_history' MCP tool. Decorated with @mcp.tool() for automatic registration. Fetches historical NAV data via the pysnowball library (imported as 'ball') and processes the response using the shared process_data helper function.
@mcp.tool() def fund_nav_history(fund_code: str="SZ000002") -> dict: """获取基金历史净值数据 Args: fund_code: 基金代码 """ result = ball.fund_nav_history(fund_code) return process_data(result) - main.py:34-61 (helper)Helper function used by the fund_nav_history tool (and others) to post-process raw data from pysnowball, primarily converting timestamps to readable dates.
def process_data(data, process_config=None): """ 通用数据处理函数，可扩展添加各种数据处理操作 Args: data: 原始数据 process_config: 处理配置字典，用于指定要执行的处理操作 例如: {'convert_timestamps': True, 'other_process': params} Returns: 处理后的数据 """ if process_config is None: # 默认配置 process_config = { 'convert_timestamps': True } # 如果开启了时间戳转换 if process_config.get('convert_timestamps', True): data = convert_timestamps(data) # 在这里可以添加更多的数据处理逻辑 # 例如: # if 'format_numbers' in process_config: # data = format_numbers(data, **process_config['format_numbers']) return data - main.py:431-431 (registration)The @mcp.tool() decorator registers the fund_nav_history function as an MCP tool.
