RISK

Why create_system_tag is rated Medium

Creating a system tag is a reversible modification operation that adds metadata to the Nextcloud system. It does not delete data (not Destructive), execute arbitrary code (not Execute), move funds (not Financial), or retrieve existing data (not Read).

From the tool's definition Tool description explicitly states 'Create a new system tag' and 'Returns the created tag info.' The 'create_' prefix and verb 'Create' indicate a write operation that generates new metadata in Nextcloud.

RECOMMENDED RULE

The rule that runs create_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 create_system_tag, this is the rule to start with:

create_system_tag Rate-limited

create_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.
