WHAT IT DOES

What appstore_developer does on Crawlora

AI agents call appstore_developer 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
`lang`	string	—	Result language tag
`dev_id`	string	Yes	Developer artist ID
`country`	string	—	Two-letter storefront country code

Parameters from the server's own tool schema.

RISK

Why appstore_developer is rated Low

Even though appstore_developer 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_developer 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_developer, this is the rule to start with:

appstore_developer Allowed

appstore_developer 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_developer": {}
  }
}

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_developer call is checked against it from then on.
