# create_polyline A write tool on the Aos MCP server. Agent View of the PolicyLayer registry record for `create_polyline`. HTML page: https://policylayer.com/tools/hybridlabor-api-aos/create-polyline ## Facts - Tool: `create_polyline` - Server: Aos (`@hybridlabor-api/aos`) — https://policylayer.com/tools/hybridlabor-api-aos.md - Install: `npx -y @hybridlabor-api/aos` - Homepage: git+https://github.com/hybridlabor-api/aos.git - 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": "create_polyline", "arguments": {} } } ``` ## Why create_polyline is rated Medium Creating a polyline is a reversible geometric operation that modifies the CAD model state by adding a new element. It does not execute arbitrary code, delete data irreversibly, or perform financial operations. The empty description lowers confidence slightly, but the context of CAD modeling tools and the tool name strongly indicate data creation/modification rather than mere querying. From the tool's own definition: "Tool name is 'create_polyline' which creates a new geometric polyline object in a CAD model. The sibling tools like 'add_hole', 'add_tap_hole', 'align_objects', 'boolean_cut', and 'assembly_add' all perform geometric modifications." ## Use case AI agents use create_polyline to create or update resources in Aos, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aos environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Aos: ```json { "version": "1", "default": "deny", "tools": { "create_polyline": { "limits": [ { "counter": "create_polyline_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Aos (718) - `archive_project` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/archive-project.md - `clear_clip_flags` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/clear-clip-flags.md - `clear_layer` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/clear-layer.md - `close_window` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/close-window.md - `delete_clip_markers` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-clip-markers.md - `delete_color_group` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-color-group.md - `delete_color_version` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-color-version.md - `delete_face` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-face.md - `delete_fusion_comp_on_clip` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-fusion-comp-on-clip.md - `delete_layer` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-layer.md - `delete_markers` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-markers.md - `delete_media_pool_clips` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-media-pool-clips.md - `delete_objects` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-objects.md - `delete_project` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-project.md - `delete_render_job` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-render-job.md - `delete_stills` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-stills.md - `delete_take` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-take.md - `delete_td_node` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-td-node.md - `delete_timeline_clips` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-timeline-clips.md - `delete_track` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/delete-track.md - `manage_checkpoint` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/manage-checkpoint.md - `remoteos_manage_instance` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/remoteos-manage-instance.md - `remove_background_clip` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/remove-background-clip.md - `repair_network` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/repair-network.md - `reset_all_grades` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/reset-all-grades.md - `unlink_media_pool_clips` — Destructive — https://policylayer.com/tools/hybridlabor-api-aos/unlink-media-pool-clips.md - `add_render_job` — Execute — https://policylayer.com/tools/hybridlabor-api-aos/add-render-job.md - `ae_render_active_comp` — Execute — https://policylayer.com/tools/hybridlabor-api-aos/ae-render-active-comp.md - `apply_glsl_top_mapping` — Execute — https://policylayer.com/tools/hybridlabor-api-aos/apply-glsl-top-mapping.md - `apply_transform` — Execute — https://policylayer.com/tools/hybridlabor-api-aos/apply-transform.md - …and 688 more: https://policylayer.com/tools/hybridlabor-api-aos.md ## For agents This record is a snapshot.
