## MCP tools (6)

### `wordstat_auth_status` (~74 tokens)

Статус авторизации wordstat: какие ключи заданы (маскированно), каких не хватает, как их получить. ВЫЗЫВАТЬ ПЕРВЫМ в начале работы с wordstat. Если чего-то нет — запросить значения у пользователя и сохранить через wordstat_set_credentials.

### `wordstat_set_credentials` (~173 tokens)

Сохранить ключи wordstat в /tmp/.config/seo-tools-mcp/.env (права 600) и применить сразу, без перезапуска сервера. Передавать только обновляемые поля. account — сохранить в именованный профиль (мультиаккаунт). Значения даёт пользователь; в ответе они маскируются.

Input parameters:

- `WORDSTAT_API_KEY` (string): Api-Key сервисного аккаунта Yandex Cloud (scope yc.search-api.execute)
- `WORDSTAT_FOLDER_ID` (string): ID каталога (folder) Yandex Cloud, где живёт сервисный аккаунт
- `account` (string): Имя аккаунта-профиля (мультиаккаунт): ключи сохранятся с суффиксом __<account>

### `wordstat_frequency` (~224 tokens)

Частотность фразы в Яндексе за последние 30 дней: широкая (freq_broad) и точная (freq_exact, «"!слово !слово"») + уточняющие запросы (related, «левая колонка» Вордстата) и похожие (associations, «правая колонка», ≤20). 2 запроса к API на вызов (квота 100/час). region: «Москва»/«Россия»/id, можно несколько через запятую.

Input parameters:

- `device` (string): all | desktop | phone | tablet (можно через запятую)
- `query` (string, required)

- `relatedLimit` (integer): Сколько уточняющих запросов вернуть

### `wordstat_dynamics` (~177 tokens)

Динамика частотности фразы: { results: [{ date, count, share }] }. ВАЖНО: операторы («!», кавычки) работают только при period=daily; monthly требует fromDate = 1-е число и toDate = последний день месяца, weekly — понедельник/воскресенье. Данные weekly/monthly с 2018 года, daily — последние 60 дней.

Input parameters:

- `account` (string): Аккаунт-профиль (мультиаккаунт, см. *_auth_status); пусто = основной
- `device` (string)
- `fromDate` (string, required): YYYY-MM-DD
- `period` (string)

### `wordstat_regions` (~146 tokens)

Распределение частотности фразы по регионам за 30 дней: { results: [{ region_id, region_name, count, share, affinityIndex }] }. affinityIndex > 100 — интерес выше среднего по стране. regionType: cities | regions | all. Имена регионов резолвятся из дерева (кеш).

Input parameters:

- `account` (string): Аккаунт-профиль (мультиаккаунт, см. *_auth_status); пусто = основной
