Tools it offers

9 tools, as the server itself reported during our check on Oct 31, 2026.

• list_appsLists the apps and rivals tracked on the account. The appId and storefront codes the other tools want come from here.
• list_keywordsLists an app's keywords in one storefront, with rank, popularity and difficulty.
• get_keywordOne keyword: its rank, its scores, its first page and the verdict - should it be targeted, and why. Every unmeasured value comes back null, never zero.
• audit_metadataAudits a draft title, subtitle and 100-character keyword field against Apple's rules and against each other. Returns what is wasted, what Apple will actually index, and the field rewritten without the waste. Nothing is s

• cusp_actionsThe keywords in the 11-30 band, ordered by popularity. The work list a metadata edit pays off on most.
