# anim_tree_create Add an AnimationTree node under a parent (undoable) with a fresh tree_root graph. root_type "blend_tree" (AnimationNodeBlendTree) or "state_machine" (AnimationNodeStateMachine). Created inactive by default; set anim_player_path to the AnimationPlayer it should drive. Agent View of the PolicyLayer registry record for `anim_tree_create`. HTML page: https://policylayer.com/tools/breakpoint-mcp/anim-tree-create ## Facts - Tool: `anim_tree_create` - Server: Breakpoint (`breakpoint-mcp`) — https://policylayer.com/tools/breakpoint-mcp.md - Install: `npx -y breakpoint-mcp` - Homepage: https://www.npmjs.com/package/breakpoint-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 5 (1 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `name` | string | no | Node name (default "AnimationTree") | | `active` | boolean | no | Whether the tree processes immediately (default false) | | `root_type` | string | no | tree_root graph type (default blend_tree) | | `parent_path` | string | yes | Parent node path relative to the scene root; "." for the root | | `anim_player_path` | string | no | NodePath to the AnimationPlayer this tree drives, relative to the AnimationTree node | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "anim_tree_create", "arguments": { "parent_path": "" } } } ``` ## Why anim_tree_create is rated Medium This tool creates a new AnimationTree node, which is a modification to the scene/project structure. It is reversible (undoable), placing it in the Write category rather than Destructive. The severity is medium because inappropriate use could corrupt animation structures or create unexpected behaviors in the animation system, but the impact is confined to animation trees and can be undone. From the tool's own definition: "Tool description states 'Add an AnimationTree node under a parent (undoable)' and 'Created inactive by default; set anim_player_path to the AnimationPlayer it should drive.' The undoable qualifier and creation of a node confirms this is a Write operation that…" ## Use case AI agents use anim_tree_create to create or update resources in Breakpoint, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Breakpoint environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Breakpoint: ```json { "version": "1", "default": "deny", "tools": { "anim_tree_create": { "limits": [ { "counter": "anim_tree_create_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Breakpoint (273) - `anim_delete` — Destructive — https://policylayer.com/tools/breakpoint-mcp/anim-delete.md - `anim_remove_key` — Destructive — https://policylayer.com/tools/breakpoint-mcp/anim-remove-key.md - `filesystem_move` — Destructive — https://policylayer.com/tools/breakpoint-mcp/filesystem-move.md - `gd_rename` — Destructive — https://policylayer.com/tools/breakpoint-mcp/gd-rename.md - `inputmap_erase_action` — Destructive — https://policylayer.com/tools/breakpoint-mcp/inputmap-erase-action.md - `mp_wire_rpc` — Destructive — https://policylayer.com/tools/breakpoint-mcp/mp-wire-rpc.md - `node_delete` — Destructive — https://policylayer.com/tools/breakpoint-mcp/node-delete.md - `project_remove_autoload` — Destructive — https://policylayer.com/tools/breakpoint-mcp/project-remove-autoload.md - `resource_save` — Destructive — https://policylayer.com/tools/breakpoint-mcp/resource-save.md - `resource_set_import_settings` — Destructive — https://policylayer.com/tools/breakpoint-mcp/resource-set-import-settings.md - `runtime_node_remove` — Destructive — https://policylayer.com/tools/breakpoint-mcp/runtime-node-remove.md - `runtime_peer_stop` — Destructive — https://policylayer.com/tools/breakpoint-mcp/runtime-peer-stop.md - `scene_close` — Destructive — https://policylayer.com/tools/breakpoint-mcp/scene-close.md - `scene_reload` — Destructive — https://policylayer.com/tools/breakpoint-mcp/scene-reload.md - `shader_set_code` — Destructive — https://policylayer.com/tools/breakpoint-mcp/shader-set-code.md - `tilemap_clear` — Destructive — https://policylayer.com/tools/breakpoint-mcp/tilemap-clear.md - `vcs_restore` — Destructive — https://policylayer.com/tools/breakpoint-mcp/vcs-restore.md - `vcs_stash` — Destructive — https://policylayer.com/tools/breakpoint-mcp/vcs-stash.md - `cs_dbg_attach` — Execute — https://policylayer.com/tools/breakpoint-mcp/cs-dbg-attach.md - `cs_dbg_continue` — Execute — https://policylayer.com/tools/breakpoint-mcp/cs-dbg-continue.md - `cs_dbg_launch` — Execute — https://policylayer.com/tools/breakpoint-mcp/cs-dbg-launch.md - `cs_dbg_restart` — Execute — https://policylayer.com/tools/breakpoint-mcp/cs-dbg-restart.md - `cs_dbg_set_breakpoints` — Execute — https://policylayer.com/tools/breakpoint-mcp/cs-dbg-set-breakpoints.md - `cs_dbg_set_exception_breakpoints` — Execute — https://policylayer.com/tools/breakpoint-mcp/cs-dbg-set-exception-breakpoints.md - `cs_dbg_set_variable` — Execute — https://policylayer.com/tools/breakpoint-mcp/cs-dbg-set-variable.md - `cs_dbg_step` — Execute — https://policylayer.com/tools/breakpoint-mcp/cs-dbg-step.md - `dbg_attach` — Execute — https://policylayer.com/tools/breakpoint-mcp/dbg-attach.md - `dbg_continue` — Execute — https://policylayer.com/tools/breakpoint-mcp/dbg-continue.md - `dbg_data_breakpoints` — Execute — https://policylayer.com/tools/breakpoint-mcp/dbg-data-breakpoints.md - `dbg_goto` — Execute — https://policylayer.com/tools/breakpoint-mcp/dbg-goto.md - …and 243 more: https://policylayer.com/tools/breakpoint-mcp.md ## For agents This record is a snapshot.
