rankcusp is an MCP server with 9 tools an agent can call, among them add_keywords, audit_metadata, country_priorities. It answers at https://rankcusp.com/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
App Store keyword ranks, the 11-30 cusp band, metadata audits and rival positions.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
add_keywords | Adds keywords to an app's tracked set in one storefront. Takes a list or a comma-separated paste. They arrive unscored - scoring costs requests to Apple and happens on the collector's schedule - so do not read a null popularity here as a ze Inputs: appId, country, keywords |
audit_metadata | Audits 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 submitted anywhere - Inputs: country, title, subtitle, keywordField |
country_priorities | Ranks the storefronts an app is tracked in by how much is winnable there: how many keywords sit in the cusp band, how many already reach the top ten, and whether the rivals' ratings leave an opening. Answers which market to work on first. Inputs: appId |
cusp_actions | The keywords in the 11-30 band, ordered by popularity. The work list a metadata edit pays off on most. Inputs: appId, country, limit |
get_keyword | One 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. Inputs: appId, country, keyword |
keyword_competitors | Who ranks for a phrase, deeper than the ten the first page carries. Use it to find the rivals a first-page reading misses - an app at 40 for a phrase you sit at 60 for is the one to study. Inputs: keyword, country, limit |
list_apps | Lists the apps and rivals tracked on the account. The appId and storefront codes the other tools want come from here. |
list_keywords | Lists an app's keywords in one storefront, with rank, popularity and difficulty. Inputs: appId, country, cuspOnly, rankedOnly, limit, offset |
ranking_keywords | Which keywords an app is already ranking for, from the pooled record of every search this product has run. Works on any App Store id, not only the ones on this account - point it at a rival to read theirs. Apple publishes no endpoint for th Inputs: appId, country, maxRank, limit |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://rankcusp.com/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
