WHAT IT DOES

What layer_duplicate does on Mcp Anything

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

RISK

Why layer_duplicate is rated Medium

Duplicating a layer creates new data (a copy of an existing layer) in what appears to be a design/animation tool context (given sibling tools like animation_*, camera_*, build_*). This is a Write operation—it modifies the project state reversibly and can be undone. Severity is medium because duplicating a layer could affect a design project's structure, but the operation is non-destructive and reversible.

From the tool's definition Tool name 'layer_duplicate' and description 'Duplicate a layer' indicate creation of a new layer by copying an existing one, which is a reversible modification operation.

RECOMMENDED RULE

The rule that runs layer_duplicate safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Anything, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For layer_duplicate, this is the rule to start with:

layer_duplicate Rate-limited

layer_duplicate 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.
