lock_account · CloudStack MCP Server MCP: Risk & Policy

WHAT IT DOES

What lock_account does on CloudStack MCP Server

WHY IT NEEDS A POLICY

Why lock_account needs a policy

Locking an account is a reversible write operation (accounts can be unlocked) that modifies account state to prevent login. While disruptive to affected users, it is not irreversible like deletion. However, it has high blast radius if misused as it can deny access to legitimate users or administrators.

lock_account Rate-limited

lock_account 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.
