MCP tools · 6 exposed · ~971 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
wordstat_auth_status ~74

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.
