RECOMMENDED RULE

The rule that runs remove_system_tag safely

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

remove_system_tag Rate-limited

remove_system_tag 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.
