Figma MCP Server currently only binds to 127.0.0.1 which makes it unable to listen on any other interface. WSL creates a virtual interface, to which the MCP Server must be able to listen, or Claude Code cannot connect to the MCP Server.
Long story short, you need to make the MCP Server configurable. As it is now, it’s useless for Claude Code users on Windows.
Hi there,
I ran into the same issue while configuring Augment Code under WSL 2 and found this sequence fixes it:
1. Press **Windows + R** to open the *Run* dialog.
2. Enter `%UserProfile%\.wslconfig` and press **Enter**.
* If the file doesn’t exist, create it in your user folder.
3. Confirm the file is named **.wslconfig** (with **no ".txt"** extension).
4. Add the following lines and save the file:
[wsl2]
networkingMode = mirrored
5. Open PowerShell as Administrator and run: wsl --shutdown
After WSL restarts, you should be able to configure MCP using 127.0.0.1 without further issues.
