What chamfer_entities does on Pypi:best Cad
AI agents use chamfer_entities 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 chamfer_entities is rated Medium
Chamfering is a reversible geometric modification operation that alters the shape of entities in a CAD drawing. This is Write-category because: (1) it modifies existing drawing geometry, (2) changes can be undone via CAD undo/redo, (3) it does not delete data irreversibly, (4) it does not execute arbitrary code or shell commands.
From the tool's definition Tool modifies CAD drawing by performing chamfer (beveled connection) operations on entities. Chinese description '对两个实体执行倒角(斜角连接)' translates to 'perform chamfer (beveled connection) on two entities', indicating geometric modification of drawing elements.
Attacks that exploit this kind of access
The rule that runs chamfer_entities 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 chamfer_entities, this is the rule to start with:
chamfer_entities 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 chamfer_entities call is checked against it from then on.
Questions about chamfer_entities
对两个实体执行倒角(斜角连接)。. 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 chamfer_entities: 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.
chamfer_entities 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 chamfer_entities 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 chamfer_entities. 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.
chamfer_entities 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.
