@ToolRegistry.register class FileTool(BaseTool): """ 综合文件处理工具，根据文件扩展名自动选择合适的处理方式 支持的文件类型： - PDF文件 (.pdf) - Word文档 (.doc, .docx) - Excel文件 (.xls, .xlsx, .xlsm) - CSV文件 (.csv) - Markdown文件 (.md) """ name = "parse_file" - mcp_tool/tools/file_tool.py:38-47 (schema)Input schema defining the required 'file_path' parameter for the tool.
