# set_object_visibility A write tool on the FreeCAD Robust MCP Server MCP server. Agent View of the PolicyLayer registry record for `set_object_visibility`. HTML page: https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/set-object-visibility ## Facts - Tool: `set_object_visibility` - Server: FreeCAD Robust MCP Server (`spkane/freecad-addon-robust-mcp-server`) — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server.md - Homepage: https://github.com/spkane/freecad-addon-robust-mcp-server - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "set_object_visibility", "arguments": {} } } ``` ## Why set_object_visibility is rated Medium This tool changes object visibility state in FreeCAD, which is a reversible modification to object properties rather than data creation/deletion. While it affects the visual representation and state of a 3D model, visibility changes can be undone and do not permanently destroy data. Classified as Write rather than Execute because it modifies an object property rather than executing arbitrary code or commands. From the tool's own definition: "Tool name 'set_object_visibility' indicates a state-modifying operation on FreeCAD objects. No description provided, but context from sibling tools (add_sketch_*, activate_workbench) shows this server manages 3D model state and properties." ## Use case AI agents use set_object_visibility 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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
