Nothing serious here today

Today is the operative word: we check rankcusp every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 9

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

keyword
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.
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.
keywords
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 zero.
list_keywords
Lists an app's keywords in one storefront, with rank, popularity and difficulty.
apps
list_apps
Lists the apps and rivals tracked on the account. The appId and storefront codes the other tools want come from here.
audit
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 - this only reads the text you pass in.
country
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.
cusp
cusp_actions
The keywords in the 11-30 band, ordered by popularity. The work list a metadata edit pays off on most.
ranking
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 this; the answer is only as wide as what has been observed, so an app nobody has swept near returns little.

rankcusp — questions

Answers built from our own checks of this server.

What can rankcusp do?
It exposes 9 tools, read directly from the server on our last check. Among them: add_keywords, audit_metadata, country_priorities, cusp_actions, get_keyword, keyword_competitors and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is rankcusp mostly used for?
Its tools cluster around keyword and keywords. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is rankcusp working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 242 ms. The bar chart above shows every period we have measured.
How do I connect rankcusp?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does rankcusp need an API key?
No. rankcusp completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is rankcusp?
It answers our handshake in 242 ms on average, which is faster than 59% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
