Verdict

Pick BlenderMCP if you prefer the more popular, battle-tested option, and you need the broadest set of tools.

Pick MCP Mermaid if you prefer its approach (generate mermaid diagrams and charts with ai dynamically, exporting to svg, png, base64, file, or shareable urls).

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.

Add MCP Mermaid

Install / run

npx -y mcp-mermaid

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

{
  "mcpServers": {
    "mcp-mermaid": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-mermaid"
      ]
    }
  }
