 Все блокеры имеют конкретный механизм; непроверенные швы подтверждены. План **готов к старту

+
+## 16. Бэклог: расширение тулсета агента (2026-06-17)
+
+> Решения сессии по составу инструментов агента в `ai-chat/tools/ai-chat-tools.service.ts`.
+
+**Сделано.** Раньше агенту были доступны только 10 тулов (поиск, чтение страницы, грубый
+CRUD страниц + create/resolve комментариев). Прокидываем в адаптер **все** оставшиеся
+возможности клиента `@docmost/mcp` (`packages/mcp/src/client.ts`), КРОМЕ удаления
+комментариев. Добавлены:
+
+- **чтение:** `getWorkspace`, `listSpaces`, `listPages`, `listSidebarPages`, `getOutline`,
+  `getPageJson`, `getNode`, `getTable`, `listComments`, `getComment`, `checkNewComments`,
+  `listShares`, `listPageHistory`, `getPageHistory`, `diffPageVersions`, `exportPageMarkdown`;
+- **обратимая запись:** `editPageText`, `patchNode`, `insertNode`, `deleteNode`,
+  `updatePageJson`, `tableInsertRow`, `tableDeleteRow`, `tableUpdateCell`, `copyPageContent`,
+  `importPageMarkdown`, `sharePage`, `unsharePage`, `restorePageVersion`, `updateComment`,
+  `transformPage`.
+
+**Сознательно НЕ прокидываем:**
+
+- `deleteComment` — hard delete комментария, необратимо (запрошено явно: «кроме удаления
+  комментариев»). По той же причине у `transformPage` НЕ экспонируем опцию `deleteComments`
+  (захардкожен `false`).
+- `uploadImage` / `insertImage` / `replaceImage` — принимают **локальный путь на ФС сервера**
+  (`filePath`, НЕ URL). Для серверного агента это бесполезно (он не может положить файл на
+  хост) и потенциально опасно — по сути примитив чтения локальных файлов хоста.
+
+**ХОТИМ СДЕЛАТЬ (TODO): вставка картинок по URL.** Научить агента вставлять изображение
+**по URL**: агент передаёт ссылку → сервер скачивает картинку через уже имеющийся
+`external-mcp/ssrf-guard.ts` (защита от SSRF / приватных адресов) → грузит во вложения
+(`POST /files/upload`) и вставляет image-узел. Это безопасная и реально работающая замена
+filePath-тулам. Требует доработки клиента (новый метод `insertImageFromUrl`, либо опция `url`
+у существующих image-методов) или обёртки в адаптере с загрузкой во временный буфер.
+
+**Замечания (учесть при ревью/эксплуатации):**
+
+- `updateComment` редактирует контент комментария БЕЗ истории версий — **необратимо**;
+  отступление от инварианта D2/D3 «агенту доступно только обратимое». Включено по явному
+  запросу (исключили лишь удаление). Серверная проверка прав остаётся: правится только свой
+  комментарий (`creatorId === authUser.id`).
+- `sharePage` делает страницу **публично доступной**; возвращаемый `publicUrl` строится от
+  `apiUrl` адаптера (loopback `127.0.0.1`), поэтому для внешней ссылки нужен публичный хост
+  (`MCP_DOCMOST_API_URL`).
