# pocket_sketch A write tool on the FreeCAD Robust MCP Server MCP server. Agent View of the PolicyLayer registry record for `pocket_sketch`. HTML page: https://policylayer.com/tools/spkane-freecad-addon-robust-mcp-server/pocket-sketch ## Facts - Tool: `pocket_sketch` - 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": "pocket_sketch", "arguments": {} } } ``` ## Why pocket_sketch is rated Medium The 'pocket_sketch' tool modifies 3D model geometry by creating or altering features in FreeCAD. This is reversible (can be edited or deleted within FreeCAD), so it classifies as Write rather than Destructive. However, it affects the design model state persistently. From the tool's own definition: "Tool name 'pocket_sketch' combined with sibling tools like 'add_sketch_arc', 'add_sketch_line', 'add_sketch_constraint' indicates manipulation of FreeCAD sketch/model geometry." ## Use case AI agents use pocket_sketch 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": { "pocket_sketch": { "limits": [ { "counter": "pocket_sketch_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.
