WHAT IT DOES

What appstore_list does on Crawlora

AI agents call appstore_list to retrieve information from Crawlora without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`num`	integer	—	Number of apps to return
`lang`	string	—	Result language tag
`country`	string	—	Two-letter storefront country code
`category`	integer	—	Numeric App Store category ID
`collection`	string	—	Collection slug
`full_detail`	boolean	—	Expand each app via lookup API

Parameters from the server's own tool schema.

RISK

Why appstore_list is rated Low

Even though appstore_list only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs appstore_list safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Crawlora, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For appstore_list, this is the rule to start with:

appstore_list Allowed

appstore_list is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "appstore_list": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Crawlora, apply this rule, and every appstore_list call is checked against it from then on.
