draw_text · AutoCAD MCP Server MCP: Risk & Policy

WHAT IT DOES

What draw_text does on AutoCAD MCP Server

AI agents use draw_text to create or update resources in AutoCAD MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AutoCAD MCP Server environment.

WHY IT NEEDS A POLICY

Why draw_text needs a policy

The tool creates new text objects in a CAD drawing, which is a Write operation—data is added/modified but not deleted and can be undone. Severity is medium because misuse could add unwanted content to a CAD project, but the effect is reversible through standard undo/delete operations.

From the tool's definition Tool name 'draw_text' and description 'Add text at a specified position in AutoCAD' indicate creation of new content within a CAD document. This is a reversible modification operation.

Verdict

draw_text Rate-limited

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.
