AI agents call get_ifc_scene_overview to retrieve information from IFC Bonsai MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to fetch or query scene metadata from an IFC model without modifying, executing, or deleting anything. The absence of descriptive text prevents absolute certainty, but the naming convention and context among sibling tools (which include create/edit operations) positions this as a read operation. Blast radius is minimal—misuse would only return scene information, not cause unintended modifications.
From the tool's definition Tool name 'get_ifc_scene_overview' indicates a query/retrieval operation that provides information about an IFC scene. No description provided, but the semantic pattern (get + overview) strongly suggests read-only data retrieval with no side effects.

{
"version": "1",
"default": "deny",
"tools": {
"get_ifc_scene_overview": {}
}
