What array_rectangular does on Pypi:best Cad
AI agents use array_rectangular 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 array_rectangular is rated Medium
The tool creates multiple copies of entities in a structured rectangular pattern, which is a data modification operation. While the operation is reversible (entities can be deleted), it modifies the drawing by adding new objects. This fits the Write category (creates or modifies data reversibly) rather than Execute, as it performs a specific CAD operation with predictable results rather than arbitrary code execution.
From the tool's definition Tool description states '按行和列复制实体' (copy entities by rows and columns), which are rectangular array operations that create new objects in the CAD drawing. This is a reversible modification operation.
Attacks that exploit this kind of access
The rule that runs array_rectangular 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 array_rectangular, this is the rule to start with:
array_rectangular 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 array_rectangular call is checked against it from then on.
Questions about array_rectangular
矩形阵列:按行和列复制实体。. 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 array_rectangular: 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.
array_rectangular 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 array_rectangular 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 array_rectangular. 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.
array_rectangular 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.
