The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 9 tools
1 auth-required 8 never probed 1 of 9 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_apps auth-required 4h ago

    Lists the apps and rivals tracked on the account. The appId and storefront codes the other tools want come from here.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • keyword_competitors unknown never probed

    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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "keyword",
    "country"
  ],

      "description": "The phrase to look up."
    }
  },
  "additionalProperties": false
}
    arguments 21 lines
  • list_keywords unknown never probed

    Lists an app's keywords in one storefront, with rank, popularity and difficulty.

      "type": "boolean",
      "description": "Only the ones ranking in the top 200."
    }
  },
  "additionalProperties": false
}
    arguments 33 lines
  • country_priorities unknown never probed

    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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "appId"
  ],
  "properties": {
    "appId": {

    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • get_keyword unknown never probed

    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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "appId",
    "country",
    "keyword"
  ],
  "properties": {

      "description": "The phrase to look up."
    }
  },
  "additionalProperties": false
}
    arguments 23 lines
  • audit_metadata unknown never probed

    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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "country"
  ],
  "properties": {
    "title": {
      "type": "string",
      "description": "Up to 30 characters."
    },
    "country": {
      "type": "string",
      "description": "Storefront code, e.g. us, tr, de"
    },
    "subtitle": {
      "type": "string",
      "description": "Up to 30 characters."
    },
    "keywordField": {
      "type": "string",
      "description": "The 100-character field, comma-separated, as App Store Connect wants it."
    }
  },
  "additionalProperties": false
}
    arguments 25 lines
  • ranking_keywords unknown never probed

    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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "appId"
  ],
  "properties": {
    "appId": {
      "type": "string",
      "description": "App Store app id"
    },
    "limit": {
      "type": "number",
      "description": "How many rows, at most 200."
    },
    "country": {
      "type": "string",
      "description": "Storefront code, e.g. us, tr, de"
    },
    "maxRank": {
      "type": "number",
      "description": "Only positions at or above this, e.g. 30 for the reachable band."
    }
  },
  "additionalProperties": false
}
    arguments 25 lines
  • add_keywords unknown never probed

    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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "appId",
    "country",
    "keywords"
  ],
  "properties": {

      "type": "string",
      "description": "App Store app id"
    },
    "country": {
      "type": "string",
      "description": "Storefront code, e.g. us, tr, de"
    },
    "keywords": {
      "type": "array",
      "items": {
        "type": "string"
      },
      "description": "The phrases to track."
    }
  },
  "additionalProperties": false
}
    arguments 26 lines
  • cusp_actions unknown never probed

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

    mcp-tool

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
