Roblox Devforum MCP vs Unity MCP

Roblox Devforum MCP tools 11

• 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.
