WHAT IT DOES

What clear_selection does on FreeCAD Robust MCP Server

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

RISK

Why clear_selection is rated Medium

Clearing a selection modifies the UI state (deselects objects) in FreeCAD. It has no destructive effect on geometry or data, but it does change the application state. It's reversible by re-selecting. Severity is low since no data or geometry is lost.

RECOMMENDED RULE

The rule that runs clear_selection safely

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

clear_selection Rate-limited

clear_selection 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.
