Quick Start

git clone https://github.com/sandraschi/blender-mcp
cd blender-mcp
just

This opens an interactive dashboard showing all available commands. Run just bootstrap to install dependencies, then just serve or just dev to start.

Manual Setup (without just)

uv sync
.venv\Scripts\activate
python run_server.py

Claude Desktop Integration

Add to your claude_desktop_config.json:

"mcpServers": {
  "blender-mcp": {
    "command": "uv",
    "args": ["--directory", "D:/Dev/repos/blender-mcp", "run", "blender-mcp"]
  }
}

Webapp Dashboard

A premium web interface for monitoring and control runs on port 10848 (backed by API on 10849).

.\start.ps1

Startup flags: -Headless (background), -BackendOnly (API only), -NoBrowser (no auto-open).

Access the dashboard at http://localhost:10848.

Available Tools (41+ tools, 170+ operations)

Key capabilities:

• Conversational 3D Creation: Natural language to professional 3D objects

• FastMCP 3.2 Integration: Advanced AI sampling and security validation

• Object Repository: Versioned asset management with intelligent search

• Cross-Platform Export: Handoff to VR platforms (VRChat, Resonite, Unity)

• VRM Avatars: Avatar pipeline for VR/AR applications

• 3D Gaussian Splatting: Import and render splats

• Grease Pencil: 2D drawing in 3D space

Documentation

• Installation Guide — full setup and troubleshooting

• Addons, Mesh, Splat — install addons from URL, search packs, download/import meshes, Gaussian splat import; webapp /mesh page

• Video Editing (VSE) — Blender's built-in video editor: add clips, transitions, text, audio; render to MP4

• Development — Ruff (lint/format), code quality, server entry points

• Usage Examples — AI construction examples, VR avatar pipeline, batch processing

• Features Overview — complete tool catalog, AI construction details, VR platform integration

• Architecture — system design, security, performance, scalability

• Troubleshooting — common issues, debug info, platform-specific problems

Native Desktop App (Tauri 2.0)

A ~15 MB installer bundles the full app — no Python, no Node.js, no git clone needed.

just build-native        # Full pipeline: webapp → PyInstaller → Tauri installer
just build-native-debug  # Debug build (skips PyInstaller)

The installer lands at native/target/release/bundle/nsis/Blender MCP_0.1.0_x64-setup.exe.

Industrial Quality Stack

Adheres to SOTA 14.1 industrial standards:

• Python: Ruff for linting and formatting. Zero-tolerance for print in core handlers (T201).

• Webapp: Biome for sub-millisecond linting. Strict noConsoleLog enforcement.

• Protocol Compliance: Hardened stdout/stderr isolation for crash-resistant JSON-RPC communication.

• Automation: Justfile recipes for all fleet operations (just lint, just fix, just dev).

• Security: Automated audits via bandit and safety.

Packaging & Distribution

SOTA 2026 compliant via @anthropic-ai/mcpb:

mcpb pack . dist/blender-mcp.mcpb

Architecture

• src/blender_mcp/server.py — Core FastMCP 3.2 server definition

• src/blender_mcp/handlers/ — Context-specific tool handlers (scene, object, render, etc.)

• src/blender_mcp/tools/ — MCP tool definitions organized by category

• src/blender_mcp/utils/ — Path resolution and Blender integration utilities

• webapp/ — React dashboard for fleet visibility

Development

uv run pytest                    # Run tests
uv run ruff check .              # Lint
uv run ruff format .             # Format
uv run mypy src                  # Type check
