No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.

Control Blender with natural language through MCP. Tell Claude to create a steampunk robot with glowing eyes and watch it build in Blender.

Download What it is
blender-mcp-*.mcpb MCP server for Claude Desktop
Blender 3D app (install separately, never bundled)
blender_bridge_addon.py (optional) Live viewport only — skip for headless use

Steps

  1. Download the .mcpb from Releases
  2. Drag it into Claude Desktop (Settings → MCP Servers → Install from file)
  3. Install Blender if you have not already
  4. Restart Claude Desktop and try: Create a red cube on a gray floor with a sun lamp.

That is enough for most tools — the server runs Blender headless in the background.

Optional — live viewport: install the bridge addon in Blender to watch the scene update while you chat. See INSTALL.md.

Other install methods (npx mcpb, manual config, developer setup): INSTALL.md

How it runs

Mode Host app When
Headless (default) blender --background subprocess Batch export, CI, agents without a display; VSE, geonodes, most mesh ops
Live GUI (optional) Blender + bridge addon Watch the agent build; viewport screenshots; sculpt with live feedback
Per-tool override prefer_session=False Batch jobs force headless even if bridge is connected

You do not need to open Blender's UI for most MCP tools — the server spawns headless Blender automatically and falls back from live session when no bridge is connected.

Install Blender separately; it is never bundled. Override path with BLENDER_EXECUTABLE.

Watch or batch — Most tools run headless. Use blender_session start + the bridge addon only if you want the viewport to update live. See INSTALL.md.
