AI agents use appstore_update_localization to create or update resources in Mimi Seed — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mimi Seed environment.
The tool creates or modifies app store metadata in a reversible manner, fitting the Write category. It does not delete data (would be Destructive), execute arbitrary code (would be Execute), or move money (would be Financial). Severity is medium because metadata modifications could impact app visibility and user perception if misused by an agent, but changes are typically reversible through the App Store dashboard.
From the tool's definition Tool description indicates it modifies (수정) app metadata: 'whatsNew', 'description', 'keywords', and promotional text (프로모션 텍스트). The description explicitly states these modifications are editable (편집) on versions in certain states like PREPARE_FOR_SUBMISSION.
Attacks that exploit this kind of access
App Store 버전 로컬라이제이션(메타데이터) 수정 — localizationId 직접 지정. 이 버전의 새로운 기능(whatsNew), 설명(description), 키워드, 프로모션 텍스트를 편집. 수정 가능한 상태(PREPARE_FOR_SUBMISSION 등)인 버전에서만 반영됨. It is categorised as a Write tool in the Mimi Seed MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mimi Seed MCP server in PolicyLayer and add a rule for appstore_update_localization: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mimi Seed. Nothing to install.
appstore_update_localization is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the appstore_update_localization rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for appstore_update_localization. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
appstore_update_localization is provided by the Mimi Seed MCP server (@yoonion/mimi-seed-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
appstore_update_localization is one line of Mimi Seed's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
