WHAT IT DOES

What fillet_edges does on FreeCAD Robust MCP Server

AI agents use fillet_edges 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 fillet_edges is rated Medium

The fillet operation creates rounded transitions on edges, which modifies the 3D model geometry. This is reversible (can be undone in FreeCAD), so it falls under Write rather than Destructive.

From the tool's definition Tool name 'fillet_edges' indicates modification of geometric edges in FreeCAD models. The sibling tools (add_sketch_arc, add_sketch_line, add_sketch_constraint, etc.) are all Write operations that create or modify sketch geometry.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

fillet_edges Rate-limited

fillet_edges 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.
