What slice_solid does on Pypi:best Cad
AI agents use slice_solid 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 slice_solid is rated Medium
The tool modifies CAD drawings by slicing/cutting 3D solids, which changes the drawing state. This is a Write operation rather than Read (it alters geometry), not Destructive (the original solid still exists in modified form rather than being deleted), and not Execute/Financial.
From the tool's definition Tool name 'slice_solid' and description indicating it performs a plane-based cutting operation on 3D solids ('用三点定义的平面对三维实体进行剖切' = 'slice 3D solids with a plane defined by three points'). This modifies the geometry of CAD objects by dividing them.
Attacks that exploit this kind of access
The rule that runs slice_solid 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 slice_solid, this is the rule to start with:
slice_solid 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 slice_solid call is checked against it from then on.
Questions about slice_solid
用三点定义的平面对三维实体进行剖切。. 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 slice_solid: 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.
slice_solid 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 slice_solid 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 slice_solid. 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.
slice_solid 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.
