add_dimensions · Solidworks MCP: Risk & Policy

WHAT IT DOES

What add_dimensions does on Solidworks

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

WHY IT NEEDS A POLICY

Why add_dimensions needs a policy

Adding dimensions to a drawing view creates new dimension objects within the drawing document. This is a Write operation because it modifies the drawing state in a reversible manner (dimensions can be edited or removed). It does not execute arbitrary code (Execute), delete anything (Destructive), or move money (Financial).

From the tool's definition Tool name is 'add_dimensions' and description states 'Add dimensions to a drawing view' — this modifies drawing metadata/properties by adding dimensional annotations, which is a reversible creation/modification operation.

add_dimensions Rate-limited

add_dimensions 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.
