AI agents call get_trimesh_examples 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 name 'get_trimesh_examples' follows the read-oriented 'get_' prefix pattern, indicating it retrieves example data without modifying state. The empty description lowers confidence slightly, but the sibling tools on this IFC/Blender server (which include creation and editing operations like create_door, create_slab, apply_style) context suggests this is a simple lookup utility.

PolicyLayer is an MCP gateway — it sits between your AI agents and IFC Bonsai MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_trimesh_examples:
{
"version": "1",
"default": "deny",
"tools": {
"get_trimesh_examples": {}
}
}get_trimesh_examples is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
