claude-code - 💡(How to fix) Fix [BUG] MCP Connections to Claude Desktop no longer work [1 comments, 2 participants]

Error Messages/Logs

TL;DR

The issue is likely due to a compatibility problem introduced in the latest Claude Code Desktop update, and reverting to a previous version or checking the API key configuration might resolve the issue.

Guidance

• Verify that the .mcp.json and claude_desktop_config.json files are correctly formatted and contain the necessary API keys for Linear and Render.
• Check the Claude Code Desktop update notes for any changes related to API key handling or MCP & Connectors setup.
• Try resetting the Claude Code Desktop configuration to its default state to see if the issue persists.
• Compare the API key configuration between the working CLI in VS Code and the non-working Claude Code Desktop to identify any differences.

Example

No code snippet is provided as the issue does not contain sufficient code-related information.

Notes

The issue seems to be specific to the Claude Code Desktop application on Windows 11, and the fact that the CLI in VS Code still works suggests that the problem might be related to the Desktop application's configuration or update.

Recommendation

Apply workaround: Given that the issue is a regression and the previous version worked, it might be worth trying to revert to a previous version of Claude Code Desktop or waiting for a patch update that addresses this issue.
