What create_group does on Pypi:best Cad
AI agents use create_group 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_group is rated Medium
This tool creates a logical grouping of CAD entities, which is a reversible modification (groups can be ungrouped). It does not delete data, execute arbitrary code, trigger financial actions, or run external commands. It falls squarely into the Write category as a create operation with limited blast radius if misused—worst case, unnecessary groups would clutter the drawing but cause no permanent damage.
From the tool's definition Tool name 'create_group' and description 'creates entity groups (groups multiple entities into a single operable group)' indicate a non-destructive create operation that modifies drawing state by organizing objects.
Attacks that exploit this kind of access
The rule that runs create_group 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_group, this is the rule to start with:
create_group 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_group call is checked against it from then on.

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