web3d-mcp is an MCP server for AI-powered 3D scene and ad generation on the web. It provides tools to generate, edit, animate, preview, validate, and export 3D scenes built with React Three Fiber (R3F). Designed for web developers and creative teams, it enables programmatic creation of production-ready interactive 3D web experiences and advertisements through natural language.
The last two health checks of this connector failed. If this server requires authentication, missing or expired test credentials may be the cause. A test profile lets Glama authenticate for health checks and discover tools; it is separate from your personal connections.

Scored across 12 tools
Most tools have clearly distinct purposes (e.g., preview vs. validate_scene). Some overlap exists between edit_scene and apply_animation regarding animation changes, but descriptions help differentiate.
Most tool names follow a verb_noun pattern in snake_case (e.g., generate_scene, export_asset). Exceptions like integration_help and optimize_for_web break the pattern slightly, but overall consistent.
With 12 tools, the set is well-scoped for the 3D scene generation pipeline, covering each step without being excessive or insufficient.
The tool surface covers the full workflow from prompt refinement to code generation and export. Minor gaps exist, such as the inability to add or remove objects after initial generation, but these are acknowledged in tool documentation.
