What create_layer does on Pypi:best Cad
AI agents use create_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 create_layer is rated Medium
This tool creates new layers or modifies properties (color) of existing layers in AutoCAD drawings. These are reversible data modifications—layers can be deleted or their properties changed again—so this falls under Write rather than Destructive. The severity is medium because modifying drawing structure could affect collaboration and downstream design work, but changes are not irreversible.
From the tool's definition Tool description states '创建新图层或修改已有图层的颜色' (create new layer or modify existing layer color). The verb 'create' and 'modify' indicate write operations on CAD drawing data.
Attacks that exploit this kind of access
The rule that runs create_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 create_layer, this is the rule to start with:
create_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 create_layer call is checked against it from then on.
Questions about create_layer
创建新图层或修改已有图层的颜色。. 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 create_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.
create_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 create_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 create_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.
create_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.
