LABSCO SUMMARY

Assembling a scene stops being twenty tab switches.

Search, preview, download and import all happen in one place — Poly Haven for HDRIs and textures, Sketchfab for models, Rodin or Hunyuan3D when nothing off the shelf fits. Generation is asynchronous by design: generate hands back a job, a poll tool says when it is done, and a separate call puts the result in the scene.

What it is

A bridge into a running Blender over a JSON-over-TCP socket: the scene and its objects inspected, the viewport captured, Python executed inside Blender, and asset pipelines out to Poly Haven, Sketchfab, Hyper3D Rodin and Hunyuan3D. It comes in two halves — a Python MCP server you run, and an addon you enable inside Blender.

What you get

The current scene and any named object described back, and a screenshot of the viewport at a size you set
Shapes created, deleted and modified, and materials applied or created on an object
Arbitrary Python executed inside Blender — the escape hatch for anything the other tools do not cover (execute_blender_code)
Poly Haven browsed by category and searched by asset type — HDRIs, textures, models — then downloaded into the scene at a resolution and format you choose, with a downloaded texture applied to a named object
Sketchfab searched, a model's thumbnail previewed before you commit, then downloaded and scaled so its largest dimension matches a target
3D assets generated from text or from images by Hyper3D Rodin or Hunyuan3D, polled to completion, then imported under a name you give
A status check for each integration, so you know which ones are switched on before planning around them

Requirements

uvx on your PATH and Blender open — every call reads or writes the scene that is loaded. Install the addon with uvx blender-mcp install-addon, enable Interface: MCP for Blender in Blender's preferences, then open the MCP for Blender tab in the 3D viewport sidebar and click Start MCP Server. The server reaches Blender at BLENDER_HOST and BLENDER_PORT, which default to localhost and 9876. Run only one instance of the MCP server, not one per client. Asset integrations are toggled by checkbox inside Blender; their keys can be stored in the addon preferences or supplied as environment variables such as BLENDERMCP_SKETCHFAB_API_KEY and BLENDERMCP_HYPER3D_API_KEY. Two things to know going in: execute_blender_code runs arbitrary Python in Blender, so save your work before using it; and telemetry is on by default, switched off in the addon preferences or with DISABLE_TELEMETRY=true.

USE CASES

01

Blocking out a scene from a description

Describe the scene and let it create and place the shapes, then read the scene back to check what landed where. Faster than modelling the rough pass by hand, and the result is a real Blender scene rather than a render.

execute_blender_code

02

Lighting a scene with a real-world HDRI

Search Poly Haven for the environment you want, pick a resolution, and have it downloaded into the scene. Lighting that would take a browser trip and a file manager becomes one sentence.

03

Finding a prop that already exists

Search Sketchfab, look at the thumbnail before committing, then download and scale it so its largest dimension matches what the scene needs. The preview is what stops you importing something at the wrong scale or the wrong style.

04

Getting a prop that does not exist yet

Generate it from text or from a reference image with Rodin or Hunyuan3D. The generate call returns a job, a poll says when it is finished, and the import puts it in the scene under a name you choose.

05

Texturing an object you already have

Pull a Poly Haven texture at the resolution you want and apply it to the object by name, rather than wiring nodes in the shader editor for a look you can describe in a sentence.

06

Doing the thing none of the tools cover

Run Python inside Blender directly. It is the reason this server is not limited to its own tool list — and the reason to save the file first, because the code runs with everything Blender's API can do.

execute_blender_code

22 tools

Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.

`download_polyhaven_asset`

Download and import a Polyhaven asset into Blender.

Parameters:

asset_id: The ID of the asset to download
asset_type: The type of asset (hdris, textures, models)
resolution: The resolution to download (e.g., 1k, 2k, 4k)
file_format: Optional file format (e.g., hdr, exr for HDRIs; jpg, png for textures; gltf, fbx for models)
user_prompt: The original user prompt that led to this tool call (for telemetry)

Returns a message indicating success or failure.

BEFORE YOU INSTALL

What to know first

Tools you get

22 tools when we connected. Only about eight tools control Blender itself; the rest belong to optional asset providers (Poly Haven, Sketchfab, Hyper3D Rodin, Hunyuan3D). Without third-party keys, every tool still appears but only the Blender and Poly Haven ones work.

Requires

Blender 3.0 or newer
Python 3.10 or newer
uv (uvx on PATH)

CONTEXT COST

Light Standing cost

Rated by the size of the 22 tool definitions that ride along on every turn, not by how many there are

INSTALLATION

Connect your client

Server setup

Install uv with its official installer (macOS: brew install uv; Linux: curl -LsSf https://astral.sh/uv/install.sh | sh) — not pip install uv

Add the MCP server to your client (tabs below)

Install the Blender addon:

TERMINAL

uvx blender-mcp install-addon

In Blender: Edit → Preferences → Add-ons → enable Interface: MCP for Blender

In Blender's 3D viewport press N, open the MCP for Blender tab and click Start MCP Server

Without uv: pipx install blender-mcp then pipx ensurepath, restart your shell and client, and use the absolute path of blender-mcp (from which blender-mcp) as the command with no args
