Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (17)
🟢localazy_list_projects(organization, languages)
List the Localazy projects the token can reach (a project token reaches one project): id, slug, name, source language, your role and visibility. Optionally add owning-organization limits (keys used/available, feature flags) and per-language progress counts (active, review, current, translated, sourceChanged, needImprovement). GET /projects.

}🟢localazy_get_file_keys(project, file_id, lang, limit, next, ...)
Read the strings of one file in one language: key id, key path, current translation (a string, an array or a plural object keyed @one/@other). Pages of up to 1000 keys; pass `next` for the following page. Set extra_info for hidden/limit/deprecated/comment, no_content to list keys without text. Counts against the project's daily fetch cap.

WRITE: set the translation of ONE source key in ONE target language. Reviewers, managers, owners and trusted translators set it as the current version (it overwrites the existing translation and goes live in the next download/CDN release); a translator's value is stored as a candidate for review. Values are stored as-is, with no placeholder, plural or length check, and the source language cannot be written. Check the reply's `stored`.

WRITE: add or update up to 50 string keys in ONE file, in ONE language (flat key -> text; use a key like "home.title" for the key name). Needs the Owner role. Nothing is deleted or deprecated, and Localazy does not overwrite existing current translations by default (translations identical to the source are skipped). By default the language is the project's source language, so this adds new source keys or changes the source text of existing ones (which marks their translations as changed); pass a different language to import translations, optionally through review with import_as_new. Imports count against the project's daily import cap (Free plan: 100/day). Returns an import_batch id for localazy_get_import_progress. POST /projects/{projectId}/import.
