Figma remote MCP not asking for authentication

[jsit]

I've followed the instructions for setting up the Figma remote MCP server:

{
  "figma": {
    "type": "http",
    "name": "Figma",
    "url": "https://mcp.figma.com/mcp"
  }
}

But when I toggle it on, I get this error:

[07:08:34]  'figma' error: Dynamic client registration failed: HTTP 403  
[07:08:34]  'figma' transport closed  
[07:08:34]  'figma' streamable-http error: Dynamic client registration failed: HTTP 403. Falling back to SSE transport  
[07:08:34]  'figma' error: SSE error: Non-200 status code (405)  
[07:08:34]  'figma' failed to start connection with http and sse transports: SSE error: Non-200 status code (405)  
[07:08:34]  'figma' failed to start connection: SSE error: Non-200 status code (405)

[07:08:34]  Failed to connect to "figma" MCP server: SSE error: Non-200 status code (405)  

This works in Cursor, for instance, where it sends me to the Figma website to authenticate.

Late response here, but I believe the issue might be due to Figma's remote MCP server allowlisting only specific clients.

See Figma forum response here: https://forum.figma.com/suggest-a-feature-11/figma-s-approach-breaks-the-core-promise-of-mcp-52507?postid=198867#post198867
