blenderwright

Formerly blend-ai. Same project, new name, nothing else changed.

The most intuitive and efficient MCP Server for Blender. Control Blender entirely through AI assistants like Claude: create 3D models, set up scenes, animate, render, and more, all through natural language.

blenderwright goes beyond tool exposure: it guides the LLM to produce professional 3D results through expert prompts, proven workflows, visual feedback, and mesh quality analysis.

A shuttle launch from two questions: "do you want to have a go at the space shuttle launch?" and then "could you animate the launch?" Claude Code (Fable 5.1) modelled the orbiter, tank, boosters and service tower, lit the plumes as emissive volumes and grew the exhaust cloud from metaballs. Keyframes lift the stack and tilt the camera after it, drivers stream the plumes and boil the smoke, and all 60 Cycles frames come back from a single render_animation call, all through blenderwright with no manual modelling:

Watch it with sound. Launch audio courtesy of NASA: STS-131, "Sound of Launch."

The still it grew from, modelled and rendered in under twenty minutes:

A two-storey Western saloon from a single sentence: "create a Western style 2-story saloon, the outside is more important than any inside detail." Claude Code (Fable 5.1) built the false front, plank siding, balcony, batwing doors and street dressing, then relit it for dusk, all through blenderwright, in about twenty minutes with no manual modelling:

Fifteen procedural materials, each built by a single create_procedural_material call. The selected ball's node graph below was generated entirely by that one call: coordinates, mapping, noise, height mask, colour ramp, and Principled BSDF, laid out and wired:

Key Features

• 276 tools across 32 modules covering every major Blender domain: modeling, mesh editing, materials, shader nodes, lighting, camera, animation, rendering, sculpting, UV mapping, physics, geometry nodes, rigging, curves, sweeps along a path, 3D-print checking, annotations, collections, file I/O, Bool Tool, viewport control, mesh quality analysis, and extension suggestions
• 13 expert prompts: topology best practices, real-world scale references, lighting principles, studio setup, character basemesh workflow, PBR material guide, auto-critique feedback loop, and more
• Visual feedback loop: fast viewport screenshots via OpenGL render (~ms, not seconds) with auto-critique prompts that guide the LLM to check its own work
• Mesh quality analysis: structured reports covering non-manifold edges, loose vertices, zero-area faces, duplicate vertices, and wire edges
• Extension suggestions: proactively recommends Bool Tool, LoopTools, and Node Wrangler when a task would benefit from them (skips already-installed extensions)
• Raw Python is opt-in: execute_blender_code is off until you tick "Allow raw Python" in the N-panel, per session, never saved into the .blend. When on, every snippet is echoed to the console and listed in the panel. A restricted namespace blocks obvious mistakes (os, subprocess, exec, open, ...); it is a guard against accidents, not a security boundary
• Render-aware: automatically detects when Blender is rendering a
