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
Opgg MCP tools 29
lol_get_champion_analysisReturns detailed champion stats (win/pick/ban rates), optimal builds (items, runes, skills, spells), skill combos, counter matchups, and team synergies for a specific champion and position. MUST call when user mentions any champion, asks for item/skill recommendations, gameplay tips, or matchup strategies. Counter picks available in weak_counters field; each counter includes my_win_rate and counter_win_rate for the head-to-head matchup. Infer position from context if not specified.lol_get_champion_synergiesReturns synergy recommendations (win rate + role fit) for your champion and the ally lane you specify.lol_get_lane_matchup_guideProvides lane matchup guidance for your champion versus a named opponent, including position-specific tips, runes, and item timings.lol_get_pro_player_riot_idLooks up a pro player alias and returns their Riot ID plus team/region metadata so you can link their OP.GG profile.lol_get_summoner_game_detailReturns full match detail (teams, participants, builds, bans) for a specific game id whenever the user drills into a single match. When the question is about one summoner's performance, also pass focus_riot_id ("gameName#tagLine"): the matching participant is flagged is_target=true — read the focused summoner's numbers from the participant row where is_target is true, never from a neighbouring participant. If no unique match is found, no row is flagged and data.game_detail.focus_error explains why.lol_get_summoner_profileReturns summoner profile with rank, tier, LP, win rate, and champion pool. MUST call for identity/profile/rank queries. DO NOT call for match history. Ask for region if not found.lol_list_aram_augmentsReturns ARAM augment stats for a champion with localized names and descriptions. Only tier 3 or higher augments are included.lol_list_champion_detailsReturns ability, tip, lore, and stat metadata for up to 10 champions (skins/media trimmed for smaller payloads).lol_list_champion_leaderboardLists the top master+ players for a champion/region so you can study their builds and match stats.lol_list_championsReturns every champion's id, key, name, and release date in the requested language.lol_list_discounted_skinsRetrieves information about champion skins that are currently on sale.lol_list_itemsReturns localized items (ids, names, descriptions, build trees, gold costs) filtered by map (default Summoner's Rift).- +17 more on the listing page
