Tools

• find_articles

  Search RBX Invest's published guides. They cover the market — how Roblox taxes resales, how RAP is calculated, valuing and flipping Limiteds, converting Robux to USD, histories of individual item series — and the site itself, in the "site" section: linking a Roblox account and what that grants, inventory syncing, privacy, what each page does. Returns titles, summaries and links — read the article itself for the detail. One search returning nothing is a vocabulary miss more often than a gap; try the words the site would use before concluding it is not there.

• find_deals

  Roblox Limiteds whose lowest resale listing is currently below their RAP, with the discount and the absolute saving. This is the live resale market, refreshed continuously. Use it for what is underpriced right now.

  shallow
• get_community_holdings

  The Limiteds and creators most held across the portfolios RBX Invest tracks. A different signal from price or sales volume: RAP says what a thing trades at, this says what people chose to keep. Ranked by total copies held or by how many different people hold it — one item can be 33 copies in a single collection and another one copy each across 400 people.

  shallow
• get_creator

  A Roblox UGC creator: how often their releases have ended up profitable, how long that typically took, and their biggest items. Creators with too few releases come back unrated rather than scored — treat that as unknown, not as bad.

  shallow
• get_item_details

  Everything tracked about one Roblox Limited: a plain-language summary paragraph, RAP and how it has moved over a window, the resale book (how many copies are listed and at what prices, not just the cheapest), stock left, sales in the last 30 days, whether the creator is still selling new copies, the creator, the item score with its predicted profit per day, and a summary of its price trend. Needs a numeric Roblox asset id — get one from search_items first. Read creator_still_selling rather than copies_remaining to answer "can I buy one at the original price": stock left does not mean it is on sale.

  shallow
• get_items

  Look up a known list of Roblox Limiteds in one call: name, classic or UGC, asset type, creator, RAP, lowest resale listing, stock, original price, favorites and the typical sale price over 30/90/180 days. Use it to compare items or to refresh a watchlist instead of calling get_item_details once per item; use get_item_details when one item needs its full history and score. Up to 200 asset ids per call; ids that are not tracked Limiteds come back in not_found.

  shallow
• get_market_cap

  How big the Roblox Limited market is over any date range, split between Classic and UGC Limiteds: market cap, items, copies in circulation, and the marketplace sales volume and Robux spent on the latest measured day, plus a sampled daily series carrying all of them. Market cap is the RAP of each item times the copies of it that exist. Use it for how big the market is, whether it is growing, how marketplace sales compare, and how the two halves differ. Item-for-item trades are excluded.

  shallow
• get_market_stats

  Totals for the Roblox Limiteds market as RBX Invest tracks it: how many Limiteds are followed, and the copies and Robux held across tracked portfolios. The holdings figures cover RBX Invest users who linked a Roblox account, not all of Roblox.

  shallow
• get_new_limiteds

  UGC Limiteds released recently, with demand level, stock left and the predicted profit numbers RBX Invest scores them with.

  shallow
• get_player_holdings

  What a tracked player holds: their most valuable positions plus the totals the leaderboard ranks them on. Follows rank_players, which returns the Roblox user id this needs. A player who set their inventory private comes back marked private rather than empty.

  shallow
• get_started_guide

  RBX Invest's guide to making Robux with Roblox Limiteds, with one guide per experience level. Level 1 is for someone who knows nothing about 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. Step 1 is getting Limiteds: buying them from creators with Robux, what makes one worth buying and what to avoid, or collecting free ones. 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. Pass level or step; omit both for the overview: the five levels, the three steps and a glossary (Robux, Limited, UGC, Classic, RAP, Roblox Plus). Returns the text with section links; paths are relative to https://rbxinvest.com.

  shallow
• rank_creators

  Creators ranked across the whole Roblox Limited market — who is biggest, and whose releases most often end up profitable. get_creator answers about one creator you can already name; this finds them. Ranking by profitability shows only creators with enough settled releases to rate, and by growth only those with 3 or more items, because an average over one release is noise.

  shallow
• rank_players

  The biggest Roblox Limited portfolios RBX Invest tracks, by total RAP held, copies held, or average lifetime appreciation. This covers people who signed up on RBX Invest and linked a Roblox account, not every Roblox player, so a rank from it is a rank on this board rather than a global one.

  shallow
• search_items

  Search the Roblox Limited catalog by name, or screen the whole market when no query is given. Returns asset id, RAP, RAP across every copy sold, the lowest resale listing, stock left, the move in RAP over 1/7/30 days and lifetime in both percent and Robux, sales counts and sales value per window, and the item score. Rank by any of those with sort, and bound any of them with filters to ask a question with more than one condition in it. Prices are Robux.
