copy_page · Collectives MCP: Risk & Policy

WHAT IT DOES

What copy_page does on Collectives

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

WHY IT NEEDS A POLICY

Why copy_page needs a policy

Copying a page creates new data in the Nextcloud Collectives system, which is a reversible write operation. While duplication could cause namespace pollution or unintended data proliferation if misused by an agent, it does not irreversibly delete data (Destructive), execute arbitrary code (Execute), involve financial operations (Financial), or move money (Financial).

From the tool's definition Tool description states "Duplicate a page" and "the copy gets that title", which creates a new reversible copy of data.

Verdict

copy_page Rate-limited

copy_page 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.

FAQ

Questions about copy_page

What does the copy_page tool do? +

Duplicate a page under the same parent. If newTitle is provided, the copy gets that title. Works for both leaf and folder pages. It is categorised as a Write tool in the Collectives MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on copy_page? +

Register the Collectives MCP server in PolicyLayer and add a rule for copy_page: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Collectives. Nothing to install.

What risk level is copy_page? +

copy_page is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit copy_page? +

Yes. Add a rate_limit block to the copy_page rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block copy_page completely? +

Set action: deny in the PolicyLayer policy for copy_page. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides copy_page? +

copy_page is provided by the Collectives MCP server (megamaced/nc_collectives-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
