WHAT IT DOES

What freeze_layer does on Pypi:best Cad

AI agents use freeze_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.

RISK

Why freeze_layer is rated Medium

Freezing a layer changes the visibility and processing state of drawing elements, which is a reversible modification of drawing properties. It does not delete data (Destructive), execute arbitrary code (Execute), or involve financial operations. While it affects rendering and performance, the operation is reversible (layers can be unfrozen), placing it in the Write category.

From the tool's definition Tool name is 'freeze_layer'; description indicates it freezes layers (makes them invisible and excludes from regeneration). This modifies layer state in the CAD drawing.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

freeze_layer Rate-limited

freeze_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.

}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Pypi:best Cad, apply this rule, and every freeze_layer call is checked against it from then on.

FAQ

Questions about freeze_layer

What does the freeze_layer tool do? +

冻结图层（图层不可见且不参与重生成，提升性能）。. 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.

How do I enforce a policy on freeze_layer? +

Register the Pypi:best Cad MCP server in PolicyLayer and add a rule for freeze_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.

What risk level is freeze_layer? +

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

Can I rate-limit freeze_layer? +

Yes. Add a rate_limit block to the freeze_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.

How do I block freeze_layer completely? +

Set action: deny in the PolicyLayer policy for freeze_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.

What MCP server provides freeze_layer? +

freeze_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.
