OAuth Setup Guide

This guide explains how to set up OAuth authentication for the Figma Console MCP server, allowing users to authenticate with their own Figma accounts.

​
Overview

OAuth authentication enables:
  • ✅ Per-user authentication - Each user authenticates with their own Figma account
  • ✅ Secure token storage - Tokens stored securely in Cloudflare Workers KV (encrypted at rest)
  • ✅ No credential sharing - No need to share personal access tokens
  • ✅ Browser-based flow - Seamless authentication experience
  • ✅ Automatic token management - Tokens managed transparently

​
Architecture

User → Claude Code → Remote MCP Server
                    ↓
        Browser OAuth Flow → Figma Authorization
                    ↓
        Token stored in Workers KV (per-session)
                    ↓
        All API calls use user's personal token

​
For Server Administrators

​
Step 1: Create a Figma OAuth App

  1. Go to Figma Developers
  2. Click “My Apps” → “Create new app”
  3. Fill in app details:
    • App name: Figma Console MCP (or your preferred name)
    • App description: AI-powered Figma debugging and design system tools
    • App website: https://github.com/southleft/figma-console-mcp
  4. Add Redirect URL: 
    https://figma-console-mcp.southleft.com/oauth/callback
    Replace figma-console-mcp.southleft.com with your actual deployment URL.
  5. Save and copy:
    • ✅ Client ID (public)
    • ✅ Client Secret (private - only shown once!)

​
Step 2: Configure Cloudflare Secrets

Set the OAuth credentials as Cloudflare Workers secrets: 
# Set Client ID
wrangler secret put FIGMA_OAUTH_CLIENT_ID
# Paste your Client ID when prompted

# Set Client Secret
wrangler secret put FIGMA_OAUTH_CLIENT_SECRET
# Paste your Client Secret when prompted
Important: Never commit these secrets to version control!

​
Step 3: Deploy Your MCP Server

npm run deploy
Or via Cloudflare Dashboard:
  1. Go to Workers & Pages → figma-console-mcp
  2. Navigate to Settings → Variables
  3. Add encrypted environment variables:
    • FIGMA_OAUTH_CLIENT_ID
    • FIGMA_OAUTH_CLIENT_SECRET

​
Step 4: Verify Configuration

Check your deployment’s health endpoint: 
curl https://figma-console-mcp.southleft.com/health
Response should include: 
{
  "status": "healthy",
  "oauth_configured": true,
  "endpoints": ["/oauth/authorize", "/oauth/callback", ...]
}

​
For End Users

​
Installation

Users simply connect to your remote MCP server - no OAuth setup needed on their end! 
claude mcp add --transport sse figma-console https://figma-console-mcp.southleft.com/sse

​
Authentication Flow

  1. First API Call: When a user calls a Figma API tool for the first time, they’ll receive an error with an authentication URL
  2. Browser Opens: Their browser automatically opens the Figma OAuth page
  3. User Authorizes: User logs in with Figma and authorizes the app
  4. Success: Browser shows success message and closes automatically
  5. All Set: Subsequent API calls work seamlessly with their personal token

​
Example User Experience

User: "Get variables from my Figma file"

Claude: Authentication required. Opening browser...
        [Browser opens → User logs in → Success!]

Claude: ✅ Retrieved 247 design variables from your file

​
Security Considerations

​
Token Storage

  • Tokens stored in Cloudflare Workers KV (encrypted at rest)
  • Scoped per-session (not shared between users)
  • Automatically cleaned up when tokens expire (90-day TTL)

​
OAuth Scopes

Currently requesting:
  • file_content:read - Read access to Figma file content
  • library_content:read - Read access to library/component content
  • file_variables:read - Read access to design variables (for Enterprise accounts)

​
Token Refresh

  • ✅ Automatic token refresh implemented
  • Tokens are automatically refreshed when expired using the refresh token
  • Users only need to re-authenticate if refresh fails or after extended inactivity

​
Best Practices

✅ DO:
  • Keep Client Secret confidential
  • Use HTTPS for all OAuth callbacks
  • Rotate secrets periodically
  • Monitor OAuth usage via Figma dashboard
❌ DON’T:
  • Commit secrets to version control
  • Share Client Secret publicly
  • Use OAuth for untrusted deployments

​
Troubleshooting

​
”OAuth not configured” Error

Symptom: Users see OAuth not configured error Solution: Ensure FIGMA_OAUTH_CLIENT_ID and FIGMA_OAUTH_CLIENT_SECRET are set in Cloudflare Workers secrets 
# Check if secrets are set
wrangler secret list

# Set missing secrets
wrangler secret put FIGMA_OAUTH_CLIENT_ID

​
”Invalid redirect_uri” Error

Symptom: OAuth callback fails with redirect URI mismatch Solution: Ensure redirect URL in Figma app settings exactly matches your deployment URL: 
https://your-domain.com/oauth/callback

​
Token Expired

Symptom: Users see “Token expired. Please re-authenticate.” Solution: User needs to call any Figma API tool to trigger re-authentication flow

​
Debugging OAuth Flow

Enable debug logging: 
# Check Cloudflare Workers logs
wrangler tail

​
Migration from Personal Access Tokens

If you’re currently using FIGMA_ACCESS_TOKEN (deprecated):
  1. Set up OAuth as described above
  2. Keep FIGMA_ACCESS_TOKEN for backward compatibility
  3. New users will automatically use OAuth
  4. Existing token-based users can continue until tokens expire
  5. Eventually remove FIGMA_ACCESS_TOKEN when all users migrated

​
OAuth App Settings

​
Scopes Requested

  • file_content:read - Read Figma file content
  • library_content:read - Read library/component data
  • file_variables:read - Read design variables (Enterprise)

​
Webhook Configuration (Optional)

Future enhancement: Set up webhooks for token revocation notifications
