WHAT IT DOES

What get_selected_elements does on Revit MCP Server

RISK

Why get_selected_elements is rated Low

This tool retrieves or lists currently selected elements in a Revit model, which is a read-only operation with no side effects. It does not create, modify, delete, or execute commands. Although the description is empty, the clear naming convention and placement among design/analysis tools support classification as Read.

From the tool's definition Tool name 'get_selected_elements' indicates retrieval of element data from the model without modification. The MCP server context (Revit design/analysis tools) and sibling tools (analyze_model_statistics, check_clashes) confirm this is a query operation.
