Feature request: toggle MCP directly in /mcp show list (Space key)

[carter003]

Summary

Please add a direct toggle interaction in /mcp show so users can enable/disable a listed MCP server without typing its name.

Current pain point

Today, users typically need commands like /mcp disable <SERVER-NAME> or /mcp enable <SERVER-NAME>, which is slow when toggling frequently.

Proposed behavior

• In /mcp show, display MCP servers as a selectable list with enabled/disabled state.
• Allow keyboard navigation (↑/↓).
• Press Space to toggle the selected MCP (on/off) immediately.
• Optional: Enter to confirm/save and Esc to cancel.

Why this matters

• Faster MCP workflow with fewer keystrokes
• Better UX for users with multiple servers
• More discoverable and ergonomic than name-based commands
