Figma Console MCP is designed with security as a priority. The project is fully open source (MIT licensed), allowing complete code auditing by security teams.

​
Architecture Security

​
Deployment Modes

Local Mode

Recommended for security-sensitive environments
  • Runs entirely on localhost via stdio
  • Zero external network calls
  • All communication stays local

Remote Mode

For browser-based MCP clients
  • SSE transport via Cloudflare Workers
  • OAuth tokens handled server-side
  • All traffic encrypted (HTTPS)

​
Data Handling

AspectDetails
Data StorageNone. No design data is persisted or cached to disk.
TelemetryNone. No analytics, tracking, or usage data collection.
LoggingLocal only. Logs stay on your machine.
CredentialsStored in your local MCP config, never transmitted to third parties.

​
Authentication

Figma Console MCP uses Figma’s native authentication:
  • Generated in Figma account settings
  • Stored locally in your MCP client config
  • Never transmitted except to api.figma.com
  • Scoped permissions based on token configuration
  • Uses Figma’s official OAuth 2.0 flow
  • Tokens managed via Figma’s authorization servers
  • No custom credential handling

​
Code Execution (figma_execute)

The figma_execute tool runs JavaScript in Figma’s plugin context:
Code runs in Figma’s plugin sandbox, not your system. It cannot access your filesystem, network, or other applications.
Sandbox limitations:
  • No filesystem access
  • No network access outside Figma’s plugin APIs
  • Cannot access other browser tabs or system resources
  • Can only modify the currently open Figma file
Mitigations:
  • Desktop Bridge must be manually started
  • All execution is user-initiated
  • Changes covered by Figma’s version history

​
Network Security

All network communication is limited to:
  • api.figma.com — Figma’s official REST API (HTTPS)
  • localhost — Local Desktop Bridge communication
  • *.workers.dev — Remote mode only (HTTPS)
No external dependencies at runtime — No third-party analytics, CDNs, or external API calls beyond Figma.

Vulnerability Reporting

To report a security vulnerability:
  1. Open a private security advisory on GitHub
  2. Include steps to reproduce and potential impact
  3. We aim to respond within 48 hours
Please use GitHub’s private security advisory feature rather than public issues.
