# mirror_object A write tool on the FreeCAD Robust MCP Server MCP server. Agent View of the PolicyLayer registry record for `mirror_object`. HTML page: https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/mirror-object ## Facts - Tool: `mirror_object` - 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": "mirror_object", "arguments": {} } } ``` ## Why mirror_object is rated Medium Mirroring is a reversible geometric transformation that modifies the 3D model state. It does not execute arbitrary code, delete data, or cause financial impact. The empty description reduces confidence slightly, but the context of FreeCAD modeling tools and the 'mirror_object' name clearly indicate a Write-class operation that transforms geometry without permanent destruction. From the tool's own definition: "Tool named 'mirror_object' in a FreeCAD 3D modeling context. Sibling tools (add_sketch_*, add_external_geometry) show this server manipulates 3D model geometry. Mirroring creates new or modifies existing objects in the model." ## Use case AI agents use mirror_object 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**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches FreeCAD Robust MCP Server: ```json { "version": "1", "default": "deny", "tools": { "mirror_object": { "limits": [ { "counter": "mirror_object_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on FreeCAD Robust MCP Server (151) - `close_document` — Destructive — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/close-document.md - `delete_macro` — Destructive — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/delete-macro.md - `delete_object` — Destructive — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/delete-object.md - `delete_sketch_constraint` — Destructive — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/delete-sketch-constraint.md - `delete_sketch_geometry` — Destructive — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/delete-sketch-geometry.md - `spreadsheet_clear_cell` — Destructive — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/spreadsheet-clear-cell.md - `activate_workbench` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/activate-workbench.md - `boolean_operation` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/boolean-operation.md - `draft_extrude_shapestring` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/draft-extrude-shapestring.md - `execute_python` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/execute-python.md - `explode_compound` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/explode-compound.md - `part_sweep` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/part-sweep.md - `recompute` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/recompute.md - `recompute_document` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/recompute-document.md - `revolution_sketch` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/revolution-sketch.md - `run_macro` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/run-macro.md - `safe_execute` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/safe-execute.md - `scale_object` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/scale-object.md - `set_camera_position` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/set-camera-position.md - `shell_object` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/shell-object.md - `slice_shape` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/slice-shape.md - `subtractive_loft` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/subtractive-loft.md - `subtractive_pipe` — Execute — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/subtractive-pipe.md - `common_all` — Other — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/common-all.md - `draft_feature` — Other — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/draft-feature.md - `draft_shapestring_to_face` — Other — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/draft-shapestring-to-face.md - `draft_text_on_surface` — Other — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/draft-text-on-surface.md - `section_shape` — Other — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/section-shape.md - `set_display_mode` — Other — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/set-display-mode.md - `set_view_angle` — Other — https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/set-view-angle.md - …and 121 more: https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server.md ## For agents This record is a snapshot.
