find_elements
Locate elements in Revit by category, returning a list of matching elements in JSON-RPC 2.0 format. Supports BuiltInCategory, Category.Name, and filters for instance or type elements.
Instructions
在Revit中按类别查找元素，返回匹配的元素信息列表，遵循JSON-RPC 2.0规范。 mcp_tool使用时params不要有任何注释信息
特性:
支持按类别BuiltInCategory或者Category.Name查找
可指定查找实例或类型元素
支持批量多个查询条件
严格遵循JSON-RPC 2.0规范
详细的错误处理和日志记录
参数: ctx (Context): FastMCP上下文对象 method (str): JSON-RPC方法名，默认为"FindElements" params (List[Dict[str, Union[str, bool]]]): 查询条件列表，每个字典包含: - categoryName (str): BuiltInCategory或者Category.Name （如"OST_Walls","OST_Doors", "墙", "门", "结构框架"等） - isInstance (bool): True查找实例,False查找类型
返回: dict: JSON-RPC 2.0格式的响应，结构为: 成功时: { "jsonrpc": "2.0", "result": [ { "elementId": "元素ID", "name": "元素名称", "familyName": "族名称" }, ... ], "id": request_id } 失败时: { "jsonrpc": "2.0", "error": { "code": 错误代码, "message": 错误描述, "data": 错误详情 }, "id": request_id }
错误代码: -32600: 无效请求（参数验证失败） -32602: 类别未找到（无效的BuiltInCategory或Category.Name） -32603: 内部错误 -32700: 解析错误（参数格式错误）
示例: >>> response = find_elements(ctx, params=[ ... {"categoryName": "OST_Doors", "isInstance": False}, ... {"categoryName": "门", "isInstance": True} ... ]) >>> print(response) { "jsonrpc": "2.0", "result": [ {"elementId": "123456", "name": "单扇门", "familyName": "M_单扇门"}, {"elementId": "789012", "name": "双扇门", "familyName": "M_双扇门"} ], "id": 1 }

Implementation Reference
- xml_revit_mcp/server.py:50-55 (registration)The find_elements tool function is included in the GENERAL_TOOLS list used for registering general purpose Revit tools to the MCP server.GENERAL_TOOLS = [ get_commands, execute_commands, call_func, find_elements, update_elements, delete_elements, parameter_elements, get_locations, move_elements, show_elements, active_view, get_selected_elements, link_dwg_and_activate_view, get_view_data ]
- xml_revit_mcp/server.py:145-147 (registration)The register_tools function registers each tool in GENERAL_TOOLS, including find_elements, to the FastMCP server using the @tool decorator equivalent.for tool in GENERAL_TOOLS: server.tool()(tool)
- xml_revit_mcp/server.py:16-16 (registration)Import statement that brings in the find_elements handler function and other tools from the tools module.from .tools import *
