Server Configuration

Describes the environment variables required to run the server.

NameRequiredDescriptionDefault
BLENDER_EXECUTABLENoPath to the Blender executable (blender.exe). Used if Blender is not at the default location.
BLENDER_CONTROL_WORKDIRNoRoot directory for storing logs and operation plans for read-only inspection tasks. Defaults to the system temp directory under blender-control-mcp.
BLENDER_TIMEOUT_SECONDSNoTimeout in seconds for a single Blender operation. Must be between 1 and 3600. Default is 180.

Instructions

Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

This server publishes no instructions, or was last inspected before Glama recorded them.

Tools

Functions exposed to the LLM to take actions

NameDescription
scene.inspectA

Open one GLB, FBX, or BLEND asset in headless Blender and return its scene structure.

Returns object names/types, material slots, mesh vertex/polygon counts, dimensions, locations, and modifier names/types. The source file is never modified.

material.listB

List materials and Principled BSDF Base Color, Roughness, Metallic, and Alpha values.

Also reports whether Base Color is node-linked, since a linked texture can visually override the socket's default value. The source file is never modified.

asset.apply_materialA

Change only allow-listed Principled BSDF values and create new GLB, BLEND, and FBX files.

target is 'all', an exact material name, or an exact object name with exactly one material. base_color accepts normalized RGB or RGBA. Scalar values are 0..1. The input is never overwritten; outputs and logs go into a unique job subfolder.

asset.transformA

Set explicit location, Euler rotation in degrees, and/or scale on target objects.

Each supplied vector must have exactly three finite numbers. target is 'all' or an exact object name. Creates new GLB, BLEND, and FBX files without changing the input.

asset.add_modifierA

Add only a Bevel or Decimate modifier to exact target mesh objects.

Bevel accepts width >0..1000 and segments 1..16 (defaults 0.1 and 3). Decimate accepts ratio 0.01..1 (default 0.5). Parameters for the other modifier are rejected. Creates new GLB, BLEND, and FBX files without changing the input.

asset.set_smooth_shadingA

Enable smooth shading on 'all' mesh objects or one exact mesh object.

Creates new GLB, BLEND, and FBX files in a unique job subfolder; never overwrites input.

asset.exportA

Export the complete asset to a non-empty unique list of GLB, BLEND, and/or FBX formats.

Outputs and logs are isolated in a new operation-ID subfolder. The input is never overwritten.
