WHAT IT DOES

What run_occ does on AIquila — Nextcloud MCP Server

AI agents invoke run_occ to trigger actions in AIquila — Nextcloud MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why run_occ is rated High

This tool runs external commands via Nextcloud's OCC interface on a server. Although described as 'allowlisted' (suggesting some controls), the ability to execute arbitrary OCC commands grants broad system-level access. OCC commands can modify system state, manage users, configure applications, and perform operations with lasting effects.

From the tool's definition Tool name 'run_occ' and description 'Execute an allowlisted Nextcloud OCC command on the server and return the output' explicitly state execution of OCC commands.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

run_occ Rate-limited

run_occ stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
