   - `AgentMcpTools` — `ListAgents`
   - `LifecycleMcpTools` — `ResetFailedTask`
   - `AppSettingsMcpTools` — `GetAppSettings` (read-only; includes `MaxParallelExecutions`)
+  - `TaskWaitMcpTools` — `WaitForTaskChange(taskIds, timeoutSeconds = 60)`: blocks until any given task leaves `Queued`/`Running`, or times out; returns immediately for a task already outside `Queued`/`Running` (unknown ids reported as status `"NotFound"`, also immediate). Implemented as an async DB poll (short-lived `DbContext` per check, 500ms delay between checks, no held connection or busy loop) rather than hooking `HubBroadcaster` — kept deliberately isolated so it can't regress the existing broadcast callers. `timeoutSeconds` is clamped server-side to `TaskWaitMcpTools.MaxTimeoutSeconds` (170s), comfortably under the list handler's `MCP_TOOL_TIMEOUT` (200s, see `InteractiveLaunchSpecService`) so the tool reports `timedOut: true` instead of racing the client's own abort. Replaces the list handler's old "sleep + poll get_task in a loop" Phase 3 instruction (`PromptFiles.MergeHelperDefault`).
   - `AttachmentMcpTools` — `AddTaskAttachment(taskId, fileName, textContent?|base64Content?)`, `ListTaskAttachments`, `RemoveTaskAttachment`. Re-attaching the same fileName overwrites; add/remove refuse on a Running task.
   - `ExternalMcpService` also exposes two daily-prep tools:
     - `GetDailyPrepCandidates` — returns Idle, non-blocked tasks in a git repo NOT excluded by `AppSettings.ReportExcludedPaths` and not already `IsMyDay`, plus the current Idle MyDay tasks and `maxTasks` (= `DailyPrepMaxTasks`). Repo-exclusion logic lives in the `DailyPrepFilter` helper (same file).
