Hi,
I'm having trouble getting the Figma Desktop MCP integration to connect with Claude.ai.
Setup:
- Latest version of Figma Desktop (macOS)
- Desktop MCP server enabled in settings
- Image source set to Local server
- Iceberg Master file open with a node selected
Issue:
The MCP panel in Dev Mode shows 'Session activity: Not sent' — the session never establishes. When I send a prompt to Claude.ai referencing a Figma node URL, Claude's tools return 'No result received from client-side tool execution' every time.
What I've tried:
- Restarting Figma Desktop
- Re-enabling the MCP server
- Selecting different nodes before sending prompts
- Starting new Claude.ai conversations
- Signing out and back in to Figma Desktop
None of these resolved the issue. The session activity remains 'Not sent' throughout.
Could you help me understand why the session isn't being established and how to fix it?
Thank you
