What draw_text does on Pypi:best Cad
AI agents use draw_text 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 draw_text is rated Medium
The tool creates new text objects in an AutoCAD drawing, which modifies the drawing's content reversibly. This fits the Write category (creates or modifies data reversibly). Severity is medium because while it modifies the drawing, the changes are not destructive and can be undone; the blast radius is limited to adding unwanted text annotations rather than corrupting or deleting critical design data.
From the tool's definition Tool description indicates '在AutoCAD中绘制单行文字' (draw single-line text in AutoCAD), which creates new graphical elements in the CAD drawing. This is a content creation/modification operation.
Attacks that exploit this kind of access
The rule that runs draw_text 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 draw_text, this is the rule to start with:
draw_text 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 draw_text call is checked against it from then on.
Questions about draw_text
在AutoCAD中绘制单行文字。. 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 draw_text: 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.
draw_text 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 draw_text 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 draw_text. 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.
draw_text 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.
