WHAT IT DOES

What copy_file does on AIquila — Nextcloud MCP Server

AI agents use copy_file 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.

Parameter	Type	Required	Description
`source`	string	Yes	The source path of the file or folder to copy
`overwrite`	boolean	—	Whether to overwrite if the destination already exists
`destination`	string	Yes	The destination path for the copy

Parameters from the server's own tool schema.

RISK

Why copy_file is rated Medium

The copy operation creates new file/folder data in Nextcloud. This is a Write action (not Read, as it modifies the filesystem state; not Destructive, as copying is fully reversible and does not delete or overwrite existing data). Severity is medium because an agent could inadvertently duplicate sensitive files, consume storage quota, or create confusion through unintended copies, but the core operation is reversible.

From the tool's definition Tool is named 'copy_file' and described as 'Copy a file or folder in Nextcloud'. Copying creates new data (a duplicate) which is a reversible write operation.

RECOMMENDED RULE

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

copy_file Rate-limited

copy_file 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.
