Hi @rumburakusai,
This is a known limitation. The Agents Window doesn’t support WSL connections yet, which is why it reads MCP settings from the Windows-side path instead of your WSL filesystem, and why you see the ENOPRO error when trying to navigate to your WSL mcp.json.
Workaround: Use the Editor Window for WSL projects. You can switch to it from the Agents Window via File > Open Editor Window, or launch Cursor in classic mode:
cursor --classic
In the Editor Window, WSL works as usual, including your MCP tools.
The team is actively working on adding WSL support to the Agents Window. You may also find this related thread helpful, with more context and updates from other users: Glass Interface doesn’t work with WSL
