# export_obj A write tool on the FreeCAD Robust MCP Server MCP server. Agent View of the PolicyLayer registry record for `export_obj`. HTML page: https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/export-obj ## Facts - Tool: `export_obj` - 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": "export_obj", "arguments": {} } } ``` ## Why export_obj is rated Medium Export functions create new files or data artifacts on the user's system, which is a Write operation (reversible data creation). Severity is medium because exported files can be saved to disk, potentially overwriting existing files or consuming storage, but the action is reversible (files can be deleted). From the tool's own definition: "Tool name 'export_obj' indicates exporting 3D model data to OBJ format. FreeCAD context shows tools for creating and modifying 3D geometry. Export operations create output files." ## Use case AI agents use export_obj 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": { "export_obj": { "limits": [ { "counter": "export_obj_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.
