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.

Tool inventory
Tools (4)
🟡audit_app(inventory, app_token)
Use before submitting a mobile or web app to the Apple App Store, Google Play or Google OAuth verification. Pass an inventory of what the app collects, which SDKs it uses and which Google scopes it requests (build it by reading the repo). Returns the problems reviewers are likely to reject, how to fix each one, and which paid package generates the missing documents. Free. The first call returns an app_token: save it in .approvekit.json at the project root and pass it on later calls so the app is updated instead of duplicated.

}🟢get_order(app_token, order_id)
Returns the payment status of an order. Once paid, returns every generated document as Markdown plus the public URLs of the hosted privacy policy and account deletion pages, ready to paste into App Store Connect, Play Console or the Google OAuth consent screen.
Input Schema
{
"type": "object",

}🟡publish_document(app_token, kind, markdown)
Saves the final version of a document after every [CONFIRM: ...] placeholder has been resolved with the user. For privacy-policy and account-deletion this makes the hosted page live at its public URL; for the other kinds it just stores the final text. Call it again whenever the text needs an update (for example after the app adds a new data type).
