Tools & Capabilities Breakdown

Seo Tools MCP Tools (11)

xmlstock_auth_status

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

xmlstock_set_credentials

Сохранить ключи xmlstock в /home/user/.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.

xmlstock_serp

Слепок выдачи Google/Yandex через XMLStock (ПЛАТНО за запрос). Возвращает { found, truncated (true = выдача кончилась раньше запрошенного depth), count, results: [{ position, url, title, snippet, text_bolds (подсветки hlword) }], serp_features: { featured_snippet, paa (только Google), related, sitelinks_top1, packs } }. Пустая выдача (код 15) ТАРИФИЦИРУЕТСЯ и помечается { results: [], empty: true, note }. depth>10 добирается пагинацией (каждая страница — отдельный платный запрос; у yandex_xml — до 100/страница). region: ОДИН регион (название или числовой id Яндекса) — работает для ВСЕХ движков. ОГРАНИЧЕНИЕ ИСТОЧНИКА: device=mobile отдаёт только позиции и сниппеты — без hlword/PAA/related; подсветки и SERP-фичи снимать с desktop. engine=yandex_xml — ОФИЦИАЛЬНЫЙ Яндекс XML (легальный API, тариф дороже: от 24 ₽/1000): groupby до 100 работает — до 100 результатов за ОДИН платный запрос (depth до 1000), hlword-подсветки на любых устройствах, статистика «найдено»: found (по запросу), found_docs (документов), found_human (строкой); в results доп. поля id/modtime/saved_copy_url/is_local. Отличие от yandex (live): SERP-фичей/packs нет — чистая органика; device/searchDomain/lang/l10n/period/exactQuery/includeAds/includeSimilar не применимы; safeSearch маппится в filter (strict/moderate/none).
