Added "explain_term"; changed the definition of "get_item_details", "get_new_limiteds" and "rank_creators" (22 tools before, 23 now)
Everything tracked about one Roblox Limited: a plain-language summary paragraph, est_demand (the Est. Demand level from the New UGC Limiteds feed, a release-time sell-out-speed quartile, not a buy signal; null when unrated), RAP and how it has moved over a ⟨186 unchanged words⟩

Demand the feed card shows, a release-time estimate of how fast the creator’s copies sell out, ranked in quarters against the last 90 days of paid releases (excellent = fastest). Sell-out speed only, not a buy signal or a guarantee; the reply carries the meaning in demand_level_meaning.

BeginnerGet Started guide to Roblox Limiteds, by experience level
RBX Invest'sthree-step beginnerguide to making Robux with Roblox Limiteds,writtenwith one guide per experience level. Level 1 is for someone who knows nothing aboutRoblox.Roblox: what Robux and Limiteds are. Level 2 is how a flip makes Robux and what it costs. Level 3 is a first flip: screening a release, break-even, the holding period, pricing an exit. Level 4 is for people who already resell: a Reseller Terminal routine, undercut alerts, lowering entry cost with the Roblox Plus discount and the 40% affiliate share, buying below RAP, Classic Limiteds. Level 5 is for daily traders: custom screens, saved views, market-wide data and this MCP server. Levels 1 and 2 lead into three beginner steps.
Added "get_started_guide" (12 tools before, 13 now)
Beginner guide to Roblox Limiteds — RBX Invest's three-step beginner guide to making Robux with Roblox Limiteds, written for someone who knows nothing about Roblox. Step 1 is getting Limiteds: buying them from creators with Robux, what makes one worth buying and what to avoid, or collecting free ones with no Robux at all. Step 2 is selling: the Roblox Plus subscription it needs, the holding period of up to 30 days, how much of a sale the seller keeps, and pricing. Step 3 is reinvesting: keep flipping UGC Limiteds and save toward Classic Limiteds, which can be traded. Omit step for the overview and a glossary (Robux, Limited, UG…

Find a page on RBX Invest — Every page on rbxinvest.com and what it is for: the market pages, the Get Started guide levels and steps, the article sections, every curated collection, the support page, the data-use and licensing terms, and the developer documents. Pass a few words of what you are looking for ("market data", "dominus", "can I reuse your data"); omit the query for the full list. Each result carries a url to cite. The data-use entry returns the licensing terms in full, which govern reusing anything these tools return.
The items in one curated collection — The items in one of RBX Invest's curated collections (for example dominus, ugc-limited-hats, cheap-limiteds-under-100, rarest-limiteds), in the same order the collection page shows them, with RAP, lowest listing and copies. find_page with a word from the collection name returns its slug. Cite the collection as https://rbxinvest.com/collections/{slug} and items as https://rbxinvest.com/item/{asset_id}.
What tracked collectors hold over time — The combined Classic and UGC value (at RAP) and copies held across every public portfolio on the RBX Invest players board, over time, with how many members that covers. It covers RBX Invest members who linked a Roblox account, not all of Roblox, and a change can be members joining as much as prices moving: compare members_at_start with members.
Marketplace sales and free claims over a period — Marketplace sales and free claims over a period, Classic and UGC Limiteds apart, each against the same length of time just before it: distinct items sold, copies sold, Robux spent, and copies claimed free (taken at 0 Robux). Use it for how much was spent, whether the market is busier than before, or how many free UGC copies were claimed. Pass creator_id for one creator's items. Item-for-item trades are excluded.
What RBX Invest costs right now — RBX Invest's membership tiers with their regular prices and what each includes, how a paid tier is obtained, and, read live, whether the site is currently free for everyone who signs in (free_right_now). When free_right_now is true, say that first: the prices apply only after the free period ends.
How fast UGC releases get claimed — UGC release cohorts: every finite UGC Limited release from one week or month taken together, how many copies they put on sale, and what share has been claimed (bought or taken free) so far and at each age. Use it to compare how fast recent drops sell through against earlier ones; compare cohorts at the same age_days. Pass creator_id for one creator's releases.
The Reseller Terminal's help text — The help text for RBX Invest's Reseller Terminal (https://rbxinvest.com/resell), the page where a signed-in member sees where each of their own resale listings sits against the market: the counters, every number on a card, search and sort, every filter, the saved views, and the Active / Snoozed / Ignore status. Pass the words a question uses as topic to get only the matching entries; omit it for the whole guide.
