claude-code - 💡(How to fix) Fix `claude mcp list` shows "Connected" even when the target port is not open — misleading status label [1 comments, 2 participants]

1. Call any tool from that server → immediate "connection refused" error

TL;DR

The claude mcp list command should be modified to accurately reflect the connection status of MCP servers, either by changing the label to "Registered" or by implementing a port reachability check.

Guidance

• Verify the current implementation of the claude mcp list command to understand how it determines the connection status of MCP servers.
• Consider adding a port reachability check before displaying the "Connected" label to ensure it accurately reflects the server's status.
• Update the label to "Registered" or "Configured" if a reachability check is not feasible, to avoid misleading users.
• Review the documentation and user interface to ensure that the new label or behavior is clearly explained to avoid user confusion.

Example

No code snippet is provided as the issue does not contain sufficient technical details about the implementation of the claude mcp list command.

Notes

The solution may require changes to the claude mcp command's implementation, and the approach may vary depending on the underlying technology and design of the system.

Recommendation

Apply a workaround by changing the label to "Registered" or "Configured" to accurately reflect the server's status, as this is a simpler and more straightforward solution that can be implemented quickly to avoid user confusion.
