WHAT IT DOES

What appstore_attach_build does on Mimi Seed

AI agents use appstore_attach_build 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.

RISK

Why appstore_attach_build is rated Medium

This tool modifies app deployment state by attaching a build to the App Store, which is a write operation (reversible, creates/modifies data). It is not destructive (the attachment can be changed), not execute (no arbitrary code), and not financial (though it may enable monetization, it doesn't move money itself).

From the tool's definition Tool name 'appstore_attach_build' indicates it attaches (associates/links) a build to the App Store. The sibling tool 'appstore_attach_latest_build' confirms this pattern.

RECOMMENDED RULE

The rule that runs appstore_attach_build safely

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

appstore_attach_build Rate-limited

appstore_attach_build 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.
