Update a specific field in an app store version localization
AI agents use update_app_store_version_localization to create or update resources in App Store Connect — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your App Store Connect environment.
This tool modifies app store version localization data (e.g., descriptions, keywords, screenshots metadata) in a reversible manner typical of Write operations. While it affects app store presentation, it does not delete data (ruling out Destructive), execute code (Execute), move money (Financial), or perform other severe actions.
From the tool's definition Tool name contains 'update' and description states 'Update a specific field in an app store version localization', indicating modification of app metadata rather than deletion or financial operations.
Documented attack patterns abuse exactly the kind of access update_app_store_version_localization gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and App Store Connect, and nothing reaches the server without passing your rules. This is the rule we recommend for update_app_store_version_localization:
{
"version": "1",
"default": "deny",
"tools": {
"update_app_store_version_localization": {
"limits": [
{
"counter": "update_app_store_version_localization_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_app_store_version_localization stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
