WHAT IT DOES

What create_block does on Pypi:best Cad

AI agents use create_block 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.

RISK

Why create_block is rated Medium

Creating a block definition is a reversible modification operation that organizes and groups drawing entities. It does not execute external code, delete data permanently, involve financial transactions, or execute arbitrary commands. However, it modifies the drawing structure and could impact downstream design work if misused.

From the tool's definition Tool name 'create_block' and description '创建图块定义（将多个实体组合为一个可重复使用的图块）' indicate creation of a reusable block definition by combining multiple entities. This is a data creation/modification operation in CAD.

RECOMMENDED RULE

The rule that runs create_block 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_block, this is the rule to start with:

create_block Rate-limited

create_block 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.
