Tools & capabilities
GameWorld Painter MCP tools 28
get_map_infoStart here. The open map: title, unit, bounds, cell size, every layer with what it holds (mask coverage, categories classes and their shares, height range, object kinds and property keys, notes, vector paths), the zones, conventions, and what the user is looking at. Coordinates: x grows east, z grows south, north is up.open_mapOpens the map in the folder at "path" (the folder with metadata.json) in GameWorld Painter. The app then reads and writes that folder through this MCP server, without the user picking it. When no app is connected, the server opens it in the default browser with a link that connects it and opens the map (the user may have to allow Chrome to reach this device). The map open before is saved first.create_mapCreates a new map in the folder at "path" (made if missing; it must not have a map yet) and opens it in the app: the bounds and cell size in the unit of the map, and a set of layers — "basic" (terrain height, ground, zones, water, roads, rivers, borders, rocks, grass, bushes, trees, buildings, enemies, chests, hiding spots, notes), "none" (no layers: make them with create_layer), "notes" (only notes), or "same" (the layers of the map open now, empty). Then shape it with the other tools.get_user_contextWhat the user is pointing at now: the selected area (its bounds and size), the selected items (their layer, kinds, ids), the selected layers, the active layer and tool, the view, the cursor, and what became of your latest changes. The user selects objects with Select (click, box) or the Select area tools (rectangle, ellipse, lasso, polygon, same kind) to show you what they mean. Use it for requests like "this area", "here", "these", "the selected ones".get_project_pathThe full path of the project folder open in the app on this computer (the folder with metadata.json and layers/), the path of every layer file, and what the app has not saved yet. Use it to read or change the files with other tools (scripts, image tools, exporters). The browser does not reveal paths, so the server finds the folder — in your workspace, your working directory, then the home folder — and checks it is the same one (its metadata.json). If it is not found, ask the user for the path and pass it as "path".render_mapAn image of the map from above (north up) with a coordinate grid: the whole map, the view, or a region. Look before and after changes. Optional highlight of a region.describe_regionEverything in a region: its size and bounds, mask coverage, categories shares (zones, ground), heights and slopes, and the items of every layer by kind. Use it to check an area before and after changing it.read_layerThe values of a mask (0–100 %), categories (class names) or height layer as a coarse grid over a region, row by row from north to south. For exact work use describe_region, find_spots or the edit tools instead of reading every cell.find_itemsItems of objects, notes and vector layers with filters: region, kind, properties, distance to a point. measure adds facts per item: the distance to the nearest feature of other layers (e.g. roads, water), the height, the slope, the zone.analyze_itemsHow items are spread in a region: nearest-neighbor distances, pairs closer than min_distance, groups (items within cluster_distance of each other) and the largest empty gaps. Use it to check or even out placements while keeping groups.find_spotsFinds the best spots in a region by a measure of the terrain and the layers, as ranked areas with a center point. open: far from cover (open, exposed ground); enclosed: much cover around (poor view, hidden); high / low: above / below the surroundings (viewpoints, hollows); flat / steep: slope; empty: far from any item and cover (looks empty); far_from / near_to: distance to given layers.analyze_walkabilityWalkable ground in a region (slope below max_slope, outside blocking layers such as water, cliffs, buildings) split into connected parts: the main part (from start, else the largest), isolated pockets where a player could get stuck or never get to, narrow passages, and items standing on blocked or isolated ground.- +16 more on the listing page

query_instancesQuery Roblox instances: get, children, find child/descendant, wait for child, class info, search by name/class. [PRO] file_tree, project_structure, descendants, ancestors, search by property/tag.mutate_instancesCreate, delete, clone, move, rename, or pivot instances. [PRO] create_tree, mass_create, mass_delete, mass_duplicate, smart_duplicate, scatter.manage_propertiesGet/set properties, attributes, and tags on instances. [PRO] set_calculated, set_relative, mass_set, mass_get, modify_children.manage_scriptsManage script source code: read, write, create, delete, edit lines, search, and validate Luau syntax. [PRO] replace across scripts.manage_uiCreate / update / verify Roblox in-game UI (ScreenGui / Frame / TextLabel / …). Always start with `design_brief`. For ambiguous input, it inspects Studio context and returns candidate brief patches; Do not dump enum lists at the user. An empty StarterGui does not prove runtime UI absence: for an existing-UI review, follow `runtime_review_required`, collect a structured Play Client PlayerGui snapshot, and pass its saved `runtimeEvidenceRef`. Pass relevant repository evidence in `projectContext`; explicit screen job, visual thesis, forbidden defaults, tokens, and approved assets determine the direction without a built-in subject preset. `design_brief` returns a primary-view-first Design Contract and an advisory Layout Plan with neutral regions, AnchorPoint strategy, and responsive behavior; it is not a hard tree preset or style quota. A calling agent may declare provider-neutral image generation capability through `agentCapabilities`; missing or unavailable capability must use the explicit existing, user-provided, Creator Store, or assetless fallback. Keep the returned `brief_id`, `design_contract`, and `layout_plan` through creation, update, preview, and check. The asset recommendation gate considers user references, project assets, existing UI, and user-approved `manage_assets.search` intent; do not use a recommendation until the user accepts it. After each meaningful create or update, preview the representative primary view and submit a calling-agent critic verdict (`recompose`, `refine`, or `approved`) with `visualReview`. Read `primary_visual_verdict`, `functional_safe`, `responsive_requirement`, `responsive_ready`, `required_dimensions`, and `readiness` separately from mutation success. Responsive evidence blocks readiness only when the Design Contract marks it required. Read `weppy://ui-studio/guide` for the authoring workflow, `weppy://ui-studio/tokens` for optional visual examples, and `weppy://ui-studio/functional-rules` for machine-readable advisory evidence rules. Design Check permits `priority_high` only for observed functional visual failures such as meaningful overlap, unreadable content, invalid geometry, or primary-view occlusion; style-only findings remain medium or low.manage_lighting[PRO] Configure environment: lighting, atmosphere, sky, terrain properties, time of day.manage_selectionGet, set, or clear selection. [PRO] context, details, add/remove items, watch changes.manage_cameraCamera operations: get info, focus on instance/position, suggest view, capture Edit-mode viewport screenshot (Edit mode only; not usable during playtest).manage_tween[PRO] Tween service: create, play, pause, cancel tweens for smooth animations.manage_audio[PRO] Audio management: play, stop, pause, resume sounds. Set audio listener.manage_animation[PRO] Animation: load, play, stop animations. Get animation tracks from humanoid/controller.manage_physics[PRO] Physics collision groups: register, set collidable between groups, list groups.- +13 more on the listing page
