Scored across 8 tools
Each tool targets a distinct operation (create, delete, get, list, transform, material, scene info, Python execution) with no overlap. An agent can easily distinguish them.
All tools follow a consistent verb_object pattern in snake_case (e.g., create_object, get_scene_info). The naming is predictable and uniform.
Eight tools cover essential 3D scene operations without being excessive. The scope is well-focused for basic Blender control via MCP.
Core CRUD (create, read, delete) and common operations (transform, material, scene info) are covered. Missing update for non-transform properties (e.g., rename) or advanced features, but acceptable for a bridge.
