[Feature Request] Add keyboard shortcut to toggle MCP enable/disable in /mcp menu

Feature Request: single-key enable/disable toggle in the /mcp list

Problem
In the /mcp server list, disabling a server takes several steps — press Enter to drill into a server, then arrow-key
to the disable option, then confirm. When toggling servers on/off frequently, that's a lot of clicks for a simple
action.

Proposed solution
From the /mcp list view (where all servers are shown), let the highlighted server be toggled enabled/disabled with a
single key — e.g. press d to toggle the currently-selected server in place, no drill-in needed. The exact key is
flexible (d for disable/toggle, or whatever fits existing bindings) — the goal is just fewer keystrokes.

Related (but distinct)

• #6309 — runtime toggle via slash commands / settings panel. This request is specifically about the in-list keyboard

UX, not command-based toggling.

• #50923 — keyboard-first shortcuts were accepted for MCP elicitation prompts; same idea, applied to the server list.
