What register_acme_account does on Proxmox MCP Server
AI agents use register_acme_account to create or update resources in Proxmox MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Proxmox MCP Server environment.
Why register_acme_account is rated Medium
This tool creates a new account credential/configuration object within the Proxmox ACME system, which is a Write category action. Severity is medium because account registration can affect SSL/TLS certificate management infrastructure, potentially enabling certificate issuance that could be leveraged for man-in-the-middle attacks if an attacker controls account registrations.
From the tool's definition Tool performs 'Register a new ACME account' — a create operation that modifies certificate management configuration state. The action is reversible (account can be deregistered) and does not delete data, execute arbitrary code, or move money.
