What isolate_layer does on Pypi:best Cad
AI agents use isolate_layer to create or update resources in Pypi:best Cad, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pypi:best Cad environment.
Why isolate_layer is rated Medium
The tool modifies drawing state by toggling layer visibility, which is a reversible operation (layers can be made visible again). This is a Write action rather than Read (it changes state) or Execute (it doesn't run arbitrary code). It's not Destructive because layer visibility changes are fully reversible.
From the tool's definition Tool description translates to 'Isolate layer: turn off all layers except the specified layer.' This modifies the state of multiple layers in the drawing by changing their visibility/on-off status.
Attacks that exploit this kind of access
The rule that runs isolate_layer safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Pypi:best Cad, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For isolate_layer, this is the rule to start with:
isolate_layer 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Pypi:best Cad, apply this rule, and every isolate_layer call is checked against it from then on.
Questions about isolate_layer
隔离图层:关闭除指定图层外的所有其他图层。. It is categorised as a Write tool in the Pypi:best Cad MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Pypi:best Cad MCP server in PolicyLayer and add a rule for isolate_layer: 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 Pypi:best Cad. Nothing to install.
isolate_layer is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the isolate_layer 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.
Set action: deny in the PolicyLayer policy for isolate_layer. 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.
isolate_layer is provided by the Pypi:best Cad MCP server (pypi:best-cad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
