figma-mcp-auth

Fix 'Dynamic Client Registration rejected (HTTP 403)' when connecting a non-catalog MCP client to Figma's remote MCP server. Mints an OAuth token via the allow-listed Codex CLI and injects it into your agent's MCP config as a Bearer header.

Installation

MCP client config (paste into mcp.json)

{
  "mcpServers": {
    "npm-figma-mcp-auth": {
      "command": "npx",
      "args": [
        "figma-mcp-auth"
      ]
    }
  }
}

Agent install prompt

Copy and paste into Cursor / Claude / other agents to install this MCP for you

Please read this MCP repository and install it into my current environment:
https://www.npmjs.com/package/figma-mcp-auth

Known working client config (can write into mcp.json):
{
  "mcpServers": {
    "npm-figma-mcp-auth": {
      "command": "npx",
      "args": [
        "figma-mcp-auth"
      ]
    }
  }
}

Please: 1) check README for deps and env vars; 2) write config for my client; 3) if secrets are missing, tell me what to fill — do not invent values.
