WHAT IT DOES

What update_share does on AIquila — Nextcloud MCP Server

AI agents use update_share to create or update resources in AIquila — Nextcloud MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AIquila — Nextcloud MCP Server environment.

RISK

Why update_share is rated Medium

This tool modifies share configurations reversibly (e.g., permissions, expiry, recipient lists) rather than deleting or destructively removing shares. It is a Write operation because it creates or modifies data reversibly. Severity is medium because misconfigured share permissions could expose files to unintended users, but the action remains reversible and does not involve financial transactions or code execution.

From the tool's definition Tool name 'update_share' and description 'Update an existing share in Nextcloud' indicate modification of existing share settings/metadata without deletion.
