WHAT IT DOES

What hatch_material does on AutoCAD MCP Pro

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

RISK

Why hatch_material is rated Medium

Tool likely modifies hatching properties in CAD drawings; reversible write operation on design data.

From the tool's definition uninformative description; hatch_material suggests modifying drawing entities

RECOMMENDED RULE

The rule that runs hatch_material safely

PolicyLayer is an MCP gateway: it sits between your AI agents and AutoCAD MCP Pro, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hatch_material, this is the rule to start with:

hatch_material Rate-limited

hatch_material 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.
