How to Access MCP OAuth Scope (mcp:connect)?

Hi Figma Community!

I'm working on a design-to-code automation tool and would like to integrate with Figma's Model Context Protocol (MCP) endpoint.

The Issue

When requesting the mcp:connect scope during OAuth authorization, I receive:

{

"error": true,

"status": 400,

"message": "Invalid scopes for app"

}

OAuth App Details:

• Redirect URI: http://localhost:3000/callback
• Current working scopes: files:read, file_comments:write
• Blocked scope: mcp:connect

Questions

1. Is the mcp:connect scope available for third-party OAuth apps?
2. If restricted, is there a beta program or application process?
3. Is this scope only available to official Figma extensions (VS Code, Cursor)?

What I've Tried

•  Standard OAuth flow works fine with public scopes
•  Got valid Bearer token
•  MCP endpoint (https://mcp.figma.com/mcp) returns 401 with www-authenticate: Bearer scope="mcp:connect"
