set_sheet_metal_thickness · Inventor MCP: Risk & Policy

WHAT IT DOES

What set_sheet_metal_thickness does on Inventor

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

WHY IT NEEDS A POLICY

Why set_sheet_metal_thickness needs a policy

This tool creates or modifies data reversibly—changing a thickness parameter can be undone or adjusted. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or trigger external operations with unpredictable effects.

From the tool's definition Tool modifies sheet metal style properties (thickness parameter) on an existing part. The description indicates it 'set[s]' a value, which is a modification operation. It operates on an active sheet metal style rather than deleting or destroying data.

set_sheet_metal_thickness Rate-limited

set_sheet_metal_thickness 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.

set_sheet_metal_thickness is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_sheet_metal_thickness? +

Yes. Add a rate_limit block to the set_sheet_metal_thickness 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.

How do I block set_sheet_metal_thickness completely? +

Set action: deny in the PolicyLayer policy for set_sheet_metal_thickness. 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.

What MCP server provides set_sheet_metal_thickness? +
