Listed by the server itself during our scan of commit 2383d7a.

• create_entities

  Create one or more entities (optionally nested hierarchies) in the current scene. Use this to add new objects: cameras, lights, models, UI, empty groups, etc. Coordinates are local to the parent; rotation is euler degrees; scale is a multiplier. Returns the created entity summaries inline (resource_

• modify_entities

  Set or unset properties on existing entities by dot-notation path. Valid top-level paths: "name", "enabled", "position" ([x,y,z] local), "rotation" ([x,y,z] euler degrees), "scale" ([x,y,z]), "tags". Component properties use "components.<type>.<prop>", e.g. "components.light.intensity", "components.

• duplicate_entities

  Duplicate existing entities (including their children) in place under the same parent. Returns the new entity summaries. Set rename=true to auto-suffix names to avoid duplicates. When NOT to use: to create a reusable prefab across scenes (create a template asset instead) or to build a brand-new enti

• reparent_entity

  Move an entity to a new parent in the hierarchy, optionally at a specific child index. Set preserveTransform=true to keep the entity at the same world position after moving. Returns the moved entity summary (including its new hierarchy path). When NOT to use: to change position/rotation values direc

• delete_entities

  Permanently delete entities and all of their descendants. This is destructive and not undoable via this tool. The scene root cannot be deleted. Returns { deleted: <count> }. When NOT to use: to temporarily hide an entity (set enabled=false via modify_entities instead) or to remove a single component

• get_entity

  Get the complete edit-time JSON for one entity by resource_id.

• list_entities

  List entities in the current scene, returning compact summaries by default (resource_id, name, hierarchy path, parent, enabled, tags, component names). Results are paginated: use limit (default 50) and offset to page through large scenes; the response meta includes total, count, hasMore and nextCurs

• resolve_entities

  Resolve entities by name into their resource_ids and hierarchy paths, so you can drive follow-up calls without shuttling UUIDs. By default matches case-insensitive substrings; set exact=true to match the full name. Returns summaries (resource_id, name, path, components). An empty result is a success

• add_components

  Add one or more components to an existing entity (camera, light, render, collision, rigidbody, element, screen, script, sound, etc.). Pass each component's initial data under its name. Returns the updated entity summary. Physics note: rigidbody/collision components only simulate when the project has

• remove_components

  Remove one or more components from an entity by component name. Returns the updated entity summary. When NOT to use: to delete the whole entity (use delete_entities) or to just disable a component (set components.<name>.enabled=false via modify_entities).

• add_script_component_script

  Add a named script to an entity that ALREADY has a script component. Returns the updated entity summary. When NOT to use: if the entity has no script component yet, prefer attach_script, which creates the component and attaches the script in one call.

• attach_script

  Attach a script to an entity in one step: creates the script component if missing, then adds the named script. This consolidates the common "add script component" + "add script" flow. Returns the updated entity summary. Note: the script must already exist as a parsed script asset (create one with cr

• add_entity_scripts

  Attach a parsed script to one or more entities, creating script components when needed.

• remove_entity_scripts

  Remove a script from one or more entities.

• move_entity_script

  Move a script to a new execution-order index on an entity.

• search_entities

  Fuzzy-search entities by name and return the best matches ranked by relevance (each as a compact summary). Use this to find an entity when you only know part of its name. When NOT to use: to filter by component or tag (use list_entities) or to find entities using a script (use find_entities_by_scrip

• find_entities_by_script

  List the entities whose script component uses a given (registered) script name. Returns compact entity summaries. When NOT to use: to search entities by name (use search_entities) or to read a script's source (use get_asset_text).

• create_assets

  Create one or more native data/text assets. Imported binary assets use upload_assets. Each asset is { type, options }; options vary by type (e.g. material takes data, script takes filename/text, template takes an entity id). Successful batches return the existing asset-summary array. Failed batches

• list_assets

  List project assets, returning compact summaries by default (id, name, type, folder, tags). Results are paginated: use limit (default 50) and offset; the response meta includes total, count, hasMore and nextCursor. Filter with type, name (case-insensitive contains) and/or tag. Use full=true only whe

• get_asset

  Get the complete JSON for one project asset by id.

• get_asset_references

  List the project assets, entities, or settings that reference an asset.

• delete_assets

  Permanently delete assets by id. This is destructive; entities referencing the deleted assets will lose those references. Returns { deleted: <count> }. When NOT to use: to remove an asset reference from an entity without deleting the asset itself (use modify_entities).

• instantiate_template_assets

  Instantiate template assets into the scene, creating entity hierarchies from them. Returns the created entity summaries. When NOT to use: for non-template assets (only type="template" assets can be instantiated) or to build an entity from scratch (use create_entities).

• upload_assets

  Upload local files into the designated project, or replace an existing asset source by providing its id. Files are limited to 512 MiB each; the result separates succeeded and failed entries.

• modify_assets

  Edit asset name, tags, preload, or data paths. Array operations are supported under data.*. Anim state graph structure and animation events require their dedicated mutation tools.

• move_assets

  Move assets to a folder in the designated project and wait until their paths update. Omit folderId to move them to the root.

• duplicate_assets

  Duplicate assets in their current folders and return the created asset summaries.

• replace_asset

  Replace references to one asset with another asset.

• reimport_assets

  Re-run the import pipeline for existing source assets and return succeeded and failed entries.

• download_asset

  Download an asset to a local file. Downloads are limited to 512 MiB and never overwrite unless overwrite=true.

• get_template_overrides

  Read the current apply/revert override records for a template instance.

• apply_template_overrides

  Apply all overrides from a template instance, or only the supplied override records.

• revert_template_overrides

  Revert all overrides on a template instance, or only the supplied override records.

• unlink_template_instances

  Unlink template instances while keeping their current entity data.

• set_material_diffuse

  Set only the diffuse (base) color of a material. Color is [r,g,b] in 0-1. When NOT to use: to change any other material property, or to set several properties at once (use set_material_properties).

• set_material_properties

  Set any combination of properties on a material asset in one call (diffuse, emissive, metalness, gloss/shininess, opacity, maps, etc.). Only the provided fields are changed; all fields are optional. Colors are [r,g,b] 0-1; map fields take asset ids. Returns the updated asset summary. When NOT to use

• get_asset_text

  Read the full text contents of a text-based asset (script, text, json, css, html, or shader), returned as text. When NOT to use: to read a script's declared name or attribute definitions (use script_parse), to read binary assets like textures or models, or to list assets (use list_assets).

• set_asset_text

  Overwrite the full contents of a CSS, HTML, JSON, script, shader, or text asset.

• set_script_text

  Overwrite the source code of an existing script asset. Provide the full file contents in text. After changing the code, call script_parse so the editor re-reads the script's name and attributes. When NOT to use: to attach a script to an entity (use attach_script) or to create the script asset itself

• script_parse

  Parse a script asset to extract its declared script name(s) and attribute definitions. Run this after set_script_text. Returns the parsed script metadata. When NOT to use: to read entity-level script attribute values (use list_entities/modify_entities).
