What's Wrong?

Using Claude desktop on Windows with Obsidian vault stored on Google drive. Previously worked but now Claude chat in desktop does not connect via MCP. Claude Code in desktop still connects fine. Asked Claude code to diagnose and it said this Already on the latest version. Let me check the Claude Desktop app version and look for any settings that might control MCP in Chat mode.

I can see the config files look fine — the MCP server is running and working (confirmed in Code mode). The problem is specifically that Chat mode stopped connecting to it.

This is most likely a Claude Desktop update that changed the behavior. Let me check one more thing.

There it is. The app just updated: version 2.1.87 → 2.1.92. This update happened today and is almost certainly what broke Chat mode's MCP access.

Here's the situation:

The MCP filesystem server works (confirmed in logs and Code mode)
Claude Desktop updated itself from 2.1.87 to 2.1.92
Chat mode lost MCP access — likely a change or bug in the new version
You have two options right now:

Option A — Report the bug and wait for a fix. Go to: https://github.com/anthropics/claude-code/issues and report that MCP filesystem tools stopped working in Chat mode after update to 2.1.92. This is the right long-term fix.
