What close_drawing does on Pypi:best Cad
AI agents use close_drawing 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 close_drawing is rated Medium
Closing a drawing is a state-modifying operation that could interrupt workflow or cause loss of unsaved changes if misused, but the action itself is reversible and does not permanently delete or corrupt data. This makes it Write rather than Destructive. The Chinese description '关闭当前图纸' (close current drawing) confirms the action is to close/unload the active drawing, not delete it.
From the tool's definition Tool closes drawings, which modifies the state of the CAD application (removes active drawing from workspace) but is reversible through reopening.
Attacks that exploit this kind of access
The rule that runs close_drawing 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 close_drawing, this is the rule to start with:
close_drawing 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 close_drawing call is checked against it from then on.

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