Tools & capabilities
Weppy Roblox MCP tools 25
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

search_devforumFull-text search across the Roblox Developer Forum. Use this first when a Roblox bug, error message, or engine behaviour needs community context: paste the literal error string (e.g. "502: API Services rejected request") or a symptom description. Results are re-ranked to favour solved and recent threads. Follow up with get_thread on the topic_id you want to read.search_bugsSearch only the DevForum bug-report categories (engine, Studio, cloud services, mobile, website, Creator Hub, purchasing). Use this to answer "is this a known Roblox bug or is it my code?" — a hit means somebody reported the same symptom, with its category, last-activity date and whether a reply was marked as the solution. Roblox does not tag reports with a public triage state, so read the thread with get_thread to see whether staff actually answered.get_threadRead a DevForum topic as Markdown: the original post plus the most useful replies, with the accepted answer hoisted to the top. Accepts a topic id or a full DevForum URL. Code blocks are preserved. Use get_replies to page through the rest.get_repliesFetch a page of replies from a DevForum topic in post order. Use after get_thread when the answer is buried further down a long thread.list_recentBrowse a category or tag without a search query. Use release-notes / announcements to check whether a recent Roblox update explains a regression, or scripting-support to see what is breaking for others right now.list_categoriesList the DevForum category tree and the most-used tags. Call this when you are unsure which category or tag slug to pass to search_devforum, search_bugs, or list_recent.search_creator_docsFind and read pages from Roblox's official creator documentation (create.roblox.com/docs). Call with `query` to list matching pages, then call again with `path` from a result to read that page in full. Use this for intended behaviour, limits and quotas, and guide-level explanations — pair it with search_devforum for what actually happens in production.check_api_healthBatch-check Roblox APIs before you ship Luau that uses them. Pass entries like "Humanoid.MoveTo", "BodyVelocity", "Enum.Material.Neon", "task.wait" or "wait" and each is verified against the live API dump and the official docs: does it still exist, is it spelled with the right case, is it deprecated (with the official replacement where the docs give one), is it locked behind a security level normal scripts cannot use, and does it yield. Use this whenever you are about to write or review Roblox code — models often reproduce APIs that Roblox retired years ago.get_engine_apiAuthoritative signature lookup from the live Roblox API dump: a class's properties, methods, events and callbacks with parameter types, security level, deprecation and thread safety. Use this to confirm a method exists, check whether it is deprecated or server-only, or find the right member name before writing Luau.get_weekly_recapRead any Roblox Weekly Recap, current or historical. Roblox publishes one every Friday summarising what shipped that week: betas, engine updates, Marketplace and Studio changes. Use `week` to step back through the archive (0 = newest, 1 = the week before, …), `before` to jump to the recap covering a past date, or `list` to see the archive index. To find when a specific feature or regression landed, list the archive and read the recaps around that date.get_whats_newA digest of recent Roblox platform changes: the official Weekly Recap, engine Release Notes, and Announcements. Use this when a game regressed for no obvious reason ("this worked last week"), when checking whether a Roblox update explains new behaviour, or when the user asks what is new on the platform. Returns the latest Weekly Recap body plus everything else published inside the time window.
