What layer_remove does on Mcp Anything
AI agents call layer_remove to permanently remove resources in Mcp Anything, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why layer_remove is rated Critical
This tool irreversibly deletes a layer from what appears to be a design/animation/media application (given sibling tools like animation_* and camera_*). Deletion operations are classified as Destructive. While the blast radius depends on context (what application, what layer), the irreversibility and potential loss of user work justify 'high' severity.
From the tool's definition The tool name "layer_remove" combined with the description "Remove a layer by index" indicates deletion of data. The verb "Remove" is explicitly destructive—layers cannot be recovered once deleted.
Attacks that exploit this kind of access
The rule that runs layer_remove 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_remove, this is the rule to start with:
layer_remove is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Anything, apply this rule, and every layer_remove call is checked against it from then on.
Questions about layer_remove

Register the Mcp Anything MCP server in PolicyLayer and add a rule for layer_remove: 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 Mcp Anything. Nothing to install.
layer_remove is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the layer_remove 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.
