    "content": "# Connect Blender 5.1+ to AI Agents via Official Blender MCP (tested)\n\nlastVerified: 2026-10-17 · blender-mcp package from lab/blender_mcp · uv + MCP SDK\n\nWire Claude Code, Cursor, Codex, or other MCP clients to a running Blender session using the **official** Blender Lab MCP server (Blender Foundation / Blender Lab). Source: https://projects.blender.org/lab/blender_mcp · Docs: https://www.blender.org/lab/mcp-server/ · License: **GPL-3.0** (see repo LICENSE).\n\n## Security (from official docs)\n\nThe MCP server can execute LLM-generated Python inside Blender with no sandbox. Official guidance: use a VM or a machine without sensitive files. Do not point this at production `.blend` files with secrets.\n\n## Requirements\n\n1. **Blender 5.1 or newer** with the Lab MCP add-on enabled (install from Blender Lab extensions: https://lab.blender.org/ or follow https://www.blender.org/lab/mcp-server/).\n2. An MCP-capable client (Claude Code, Cursor, Codex, Windsurf, etc.).\n3. The `blender-mcp` stdio (or HTTP) server process.\n\n## Tested on this box (2026-10-17)\n\nBlender GUI was **not** available here, so add-on + live scene tools were not end-to-end exercised. These steps **were** verified:\n\n```bash\ngit clone https://projects.blender.org/lab/blender_mcp.git\ncd blender_mcp/mcp\n# Optional: uv venv && source .venv/bin/activate\nuv pip install -e .\nblender-mcp --help\n# usage: blender-mcp [-h] [--transport {stdio,http}] [--host HOST] [--port PORT]\n```\n\nPackage version in pyproject.toml at clone time: `1.0.2`. Installed MCP SDK `1.30.0`. Discovered tool modules include `execute_blender_code`, `get_objects_summary`, `get_python_api_docs`, `search_manual_docs`, viewport/screenshot helpers, and render-to-path tools.\n\n## MCP client config (stdio + uv)\n\nReplace the directory with your real clone path (clients often do not expand `$HOME`):\n\n```json\n{\n  \"mcpServers\": {\n    \"blender\": {\n      \"command\": \"uv\",\n      \"args\": [\n        \"--directory\",\n        \"/ABSOLUTE/PATH/blender_mcp/mcp\",\n        \"run\",\n        \"blender-mcp\"\n      ]\n    }\n  }\n}\n```\n\nAlternate install: `pip install git+https://projects.blender.org/lab/blender_mcp.git#subdirectory=mcp` then point `command` at `blender-mcp` on your PATH.\n\nHTTP transport (local only): `blender-mcp --transport http --host 127.0.0.1 --port 8000`.\n\n## After connect\n\n1. Launch Blender 5.1+, enable the MCP add-on, confirm it is listening.\n2. Start the client so it spawns `blender-mcp`.\n3. Ask the agent to inspect the scene first (`get_objects_summary` / API docs) before any destructive edits.\n4. Good first prompts (from Blender Lab demos): rename typo'd data-blocks; list objects using a material; find high-poly outliers relative to camera size.\n\n## Attribution\n\nOfficial project by Blender Lab / Blender Foundation.
