Figma MCP Server stopped working with Antigravity – Token / Authentication issues
Hi everyone,
I'm using the Figma MCP integration (`@modelcontextprotocol/server-figma`) with Google Antigravity to read design files and components into my development environment.
Everything was working properly initially, but recently it started failing and throwing authentication/token-related errors when attempting to query files or nodes.
Setup details:
Client: Google Antigravity (configured via `mcp_config.json`)
Token Type: Personal Access Token (PAT) with file read permissions
Environment:Token passed as `FIGMA_ACCESS_TOKEN` under server `env`
Current Situation:
- The integration was working previously without any issues, but suddenly started failing.
- I am experiencing this issue in Antigravity (though I haven't tested it with other MCP clients yet).
- I've verified the token is present in the configuration, but the connection/auth still fails.
Questions:
1. Have there been any recent changes to Figma PAT formats, expiration policies, or REST API authentication endpoints?
2. Has anyone experienced intermittent token rejection or sudden scope invalidation with MCP servers?
3. Are there known compatibility issues or extra environment variables needed for MCP clients running on Windows/Antigravity?
Thanks in advance for any insights or fixes!
