RISK

Why add_sketch_slot is rated Medium

Based on the naming pattern and context of sibling tools, this tool likely adds a slot shape to a FreeCAD sketch, which is a Write operation (creating/modifying 3D model data). Confidence is reduced because the description is empty.

From the tool's definition Tool name 'add_sketch_slot' and sibling tools like 'add_sketch_arc', 'add_sketch_circle', 'add_sketch_line' all follow the pattern of adding geometry to a sketch in FreeCAD.

RECOMMENDED RULE

The rule that runs add_sketch_slot 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 add_sketch_slot, this is the rule to start with:

add_sketch_slot Rate-limited

add_sketch_slot 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.
