Verdict

Pick BlenderMCP if you prefer the more popular, battle-tested option, and you want zero-setup with no API key.

Pick 21st.dev Magic MCP if you want the official, vendor-maintained server.

Add BlenderMCP

Install / run

uvx blender-mcp

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "blendermcp": {
      "command": "uvx",
      "args": [
        "blender-mcp"
      ]
    }
  }
}

Requires `uv` (the Python package runner). Install it from https://docs.astral.sh/uv/ if `uvx` is not found.

Install / run

npx @21st-dev/cli@latest install <client> --api-key <key>

        "-y",
        "@21st-dev/magic@latest",
