TL;DR

The issue can be mitigated by increasing the terminal window size to ensure all MCP servers are visible in the /mcp TUI dialog.

Guidance

• Verify that the terminal window size is the cause of the issue by resizing the window to a larger size and checking if all MCP servers appear in the dialog.
• Check if there are any configuration options in Claude Code to adjust the TUI dialog's behavior for small terminal windows.
• Test the /mcp command with a smaller set of MCP servers to see if the issue is related to the number of servers being displayed.
• Consider reporting the issue with more details about the previous version where the feature worked, to help identify the regression cause.

Example

No code snippet is provided as the issue is related to a specific tool's behavior and not a code-based problem.

Notes

The issue seems to be a regression, and providing more information about the last working version could help in identifying the cause. The Anthropic API and iTerm2 terminal are specific to this issue, but the problem might be related to the Claude Code version or its interaction with the terminal.

Recommendation

Apply workaround: Increase the terminal window size to ensure all MCP servers are visible, as this is a simple and immediate way to mitigate the issue, although it does not address the underlying regression.
