Tools cluster into clear provider groups (Polyhaven, Sketchfab, Hyper3D, Hunyuan3D), but within 3D generation, generate_hyper3d_model_via_text, generate_hyper3d_model_via_images, and generate_hunyuan3d_model are near-interchangeable from an agent's perspective, differing only by backend service. The parallel poll/import pairs are distinguishable mostly because of naming luck, and set_texture's relationship to download_polyhaven_asset is ambiguous.

Consistent snake_case verb_noun pattern and a clear provider-prefix convention (polyhaven_, sketchfab_, hyper3d_, hunyuan3d_) makes the set predictable. Deviations include set_texture (drops the provider prefix) and the inconsistent modifier ordering of import_generated_asset_hunyuan vs the pattern used elsewhere, which slightly breaks parallel structure.

At 22 tools, the server is on the heavy side—reasonable given that it covers four asset providers plus scene introspection, but it exceeds the ideal 15-tool ceiling. The repeated status-poll-import triads across three generation backends inflate the count without adding conceptual surface area.

Each provider's core lifecycle is covered (status check, search, download/import for asset libraries; generate, poll, import for gen-AI models), and get_viewport_screenshot provides useful scene feedback. Gaps include no way to enumerate previously downloaded Polyhaven textures despite set_texture requiring a downloaded ID, no cancellation/list of active jobs, and execute_blender_code serving as an awkward catch-all for anything outside the defined tools.
