Connecting Figma MCP Server with Google Antigravity

I think it’s still not working for linux. I get this while installing figma mcp via antigravity gui:

Solution: Just install node.js https://nodejs.org/en/download/current, once installed restart your device for the path to work.

Reinstall the mcp.

 I had version 22 of the node, then updated to 25 and it's still not working. Any other tips?

I can’t even i use latest nodejs but issue still happen :(

Anyone know how do I fix this?

Check if you open up your FIGMA MCP (dev mode)

Update mcp_config.json to this works for me. I don’t use local mcp server

{
  "mcpServers": {
    "figma-dev-mode-mcp-server": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp.figma.com/mcp"
      ],
      "env": {}
    }
  }
}

Everything works. 😀 I'm an amateur at this sort of thing, so I pasted a screenshot of the problem into Google Gemini Pro. It gave me step-by-step instructions on how to run MCP and connect Figma<->Antigravity. I recommend it.

this work fine with me for development tools.

This worked for me wonderfully, thanks!

Thank you it worked for me on linux.

For me what worked was: 

{
  "mcpServers": {
    "figma-developer-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "figma-developer-mcp",
        "--stdio"
      ],
      "env": {
        "FIGMA_API_KEY": "your-personal-access-token-here"
      }
    }
  }
}
