Open-source MCP servers and skills that let Claude Code, Codex and other agents work in 3D, security-graded: Blender, Unity, Godot, Unreal, CAD, Three.js and 3D model generation. Vet before you install.
Of the 118 Blender, Unity & Godot MCP and 3D Skills here, the best one to start with is mcp-for-blender (rated SAFE by our security scan, ★ 33.3k). Community plugin to control Blender 3D with any LLM of your choice. Not affiliated with the official Blender Foundation.
A Blender MCP server lets an AI assistant such as Claude Code, Claude Desktop, Codex or Cursor operate Blender through the Model Context Protocol (MCP). It comes in two parts: an add-on inside Blender that opens a local socket, and an MCP server your assistant launches, which turns its requests into commands: create and edit objects, set materials, run Blender Python, render views to check the result. Unity, Godot and Unreal MCP servers do the same for game engines, and CAD ones for FreeCAD or SolidWorks; most need the app open on your own machine.
For Blender. The Blender MCP most people mean, formerly blender-mcp: a Blender add-on plus an MCP server that lets Claude create and edit objects, set materials, run Blender Python and render views to check its work, and bring in Poly Haven, Sketchfab and AI-generated models. A third-party project, not made by Blender.
For Unity. It connects Claude, Codex, VS Code and other MCP clients to the Unity Editor: create scenes and GameObjects, edit C# scripts, manage assets, run tests, profile and build, through 50 tools. Free and MIT-licensed.
For Unreal Engine, from Epic Games. A Claude Code plugin that drives the Unreal Editor over MCP, with hundreds of tools across more than 30 toolsets (actors, Blueprints, materials, Niagara, Sequencer and more). Needs the Editor running with its ModelContextProtocol and AllToolsets plugins enabled.
For CAD. Through an add-on inside FreeCAD, it lets Claude Desktop and other MCP clients create and edit models, run Python scripts, inspect documents and run FEM analyses.
For 3D on the web. Skill files that give Claude Code current knowledge of three.js r186, React Three Fiber 9.8 and drei 10.7, so the code it writes runs on the release you install, not on one from its training data.
One per app, picked from this page by what each does and its security grade (all five rated SAFE). We have not run these end to end.
Blender, Unity & Godot MCP and 3D Skills are AI-powered software designed to help developers and teams tackle blender, unity & godot mcp-related tasks more efficiently. These tools are typically published as open-source projects on GitHub and can be integrated into existing workflows via MCP (Model Context Protocol), Claude Skills, or standalone agent frameworks. On Agent Skills Hub, we index 118 quality-scored Blender, Unity & Godot MCP and 3D Skills across languages including Python, TypeScript, C#.
In 2026, the AI agent ecosystem is maturing rapidly. Blender, Unity & Godot MCP and 3D Skills can significantly boost development efficiency by automating repetitive tasks, reducing human error, and providing intelligent suggestions. The top 3 tools — mcp-for-blender, editor, unity-mcp — have earned an average of 24,741 GitHub stars. 95 of the listed tools come with clear open-source licenses, ensuring freedom to use and modify.
When choosing among Blender, Unity & Godot MCP and 3D Skills, consider these factors: 1) Community activity — GitHub stars and recent commit frequency indicate reliability; 2) Integration method — check if it supports MCP, Claude, or your preferred agent framework; 3) Language compatibility — the most common language in this list is Python; 4) Quality score — Agent Skills Hub's composite score evaluates code quality, documentation completeness, and maintenance activity. Our recommendation: start with mcp-for-blender — it ranks highest in both star count and quality score.

The top blender, unity & godot mcp tools in 2026 are mcp-for-blender, editor, unity-mcp. Agent Skills Hub ranks 118 options by GitHub stars, quality score (6 dimensions including completeness, examples, and agent readiness), and recent activity. The list is rebuilt every 8 hours from live GitHub data.
mcp-for-blender (33.3k stars) is the most adopted choice for general blender, unity & godot mcp workflows, written in Python. editor (25.4k stars) is a strong alternative and uses TypeScript instead. Pick by your existing stack: match the language and runtime your team already uses to minimize integration cost. If unsure, start with mcp-for-blender — it has the deepest community and the most examples online.
Avoid pre-built blender, unity & godot mcp tools when (1) your use case requires deep customization that the tool's plugin system doesn't support, (2) you have strict compliance requirements that ban third-party dependencies, (3) the tool's maintenance is inactive (last commit >6 months ago), or (4) your data volume is small enough that a 50-line custom script is cheaper than learning the tool. For most production workflows above 100 requests/day, the time savings from a maintained tool outweigh the customization loss.
Blender, Unity & Godot MCP focuses specifically on open-source mcp servers and skills that let claude code, codex and other agents work in 3d, security-graded: blender, unity, godot, unreal, cad, three.js and 3d model generation. vet before you install. Image Generation is a related but distinct category — see https://agentskillshub.top/best/image-generation/ for those tools. The two often appear in the same agent pipeline but solve different problems: choose blender, unity & godot mcp when your primary goal is the specific task, and image generation when the workflow is broader.
For most teams, yes. mcp-for-blender has 33.3k stars worth of community testing, handles edge cases you haven't thought of, and ships with documentation. Build your own only when (1) your requirements are deeply non-standard, (2) you have a security/compliance reason to avoid OSS dependencies, or (3) the maintenance burden is small enough (<200 lines of code) that you'll save time long-term. The break-even point is usually around 2-3 weeks of dev time saved.
Most blender, unity & godot mcp tools listed are open source under permissive licenses (MIT, Apache 2.0). A handful offer paid managed/cloud versions on top of free self-hosted core. Always check the LICENSE file on each tool's GitHub repository before commercial use — some use AGPL or non-commercial restrictions that may not fit your deployment model.
Grades come from a rule-based scan built on the SlowMist agent-security taxonomy: 42 published rules, covering credential harvesting, data exfiltration, curl | sh installers and more. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
