BlenderLens MCP server

BlenderLens

An MCP server that lets an AI agent model, texture and animate in Blender, from a single object to a whole animated scene. You can watch the agent work in your own Blender window and undo anything it does, or let it work in a background Blender with no window. The result is an ordinary .blend file, or an export in the format you need.

What it can do

Once the server is connected, you describe what you want and the agent builds it in Blender. With BlenderLens it can:

inset, bevel, bisect, solidify and subdivide, or add any Blender modifier.

• Model: start from primitives, tubes along a path, lathed profiles, 3D text or raw vertices, then extrude,

ambient occlusion, normal and lighting textures.

• Texture: PBR materials with emission and transparency, vertex colours, UV unwrapping, and baked colour,

build scripts.

• Animate: key movement, rotation, scale and shape keys into named clips.
• Assemble scenes: place, parent, duplicate and group objects, and drop them until they rest on what is below.
• See its work: render previews from any angle, or a sheet of several views, in shaded, clay or wireframe style.
• Check: measure parts, find ones that pass through each other, and catch broken geometry before you do.
• Deliver: save the .blend, or export glTF, FBX, OBJ, STL, PLY or USD; import existing models; run your own

Built for AI agents

An agent can already drive Blender by writing Python, but it works blind: it cannot see the result, guesses at geometry it cannot inspect, and finds out what went wrong only when you open the file. BlenderLens gives it the feedback a person modelling in Blender gets.

Two ways to run

Blender you have open. You see each change as it happens, can step in at any point, and can press Ctrl+Z to undo any call.

• In your Blender window. Install the BlenderLens add-on and press Start, and the agent works in the

needs it, and keeps it until the server exits. Nothing to set up in Blender.

• In the background. With no add-on, the server starts blender --background itself on the first call that

By default the server uses your window when the add-on is started, and a background Blender otherwise.
