Install

How do I install the RBX Invest Roblox Limiteds market data MCP server?

RBX Invest Roblox Limiteds market data is a hosted endpoint at https://rbxinvest.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
find_articles ~186

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.

NameTypeReqDescription
categorystringRestrict to one section of /articles, the same six a visitor can browse.
limitinteger
querystringTopic to search for, e.g. "devex", "how RAP works". Omit for the most recent articles.

No output schema declared.

No examples provided.

find_deals ~169

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.

NameTypeReqDescription
limitinteger
max_priceintegerHighest resale price to consider, in Robux.
min_discount_pctnumberOnly items at least this far below RAP.
min_priceintegerLowest resale price to consider, in Robux.
min_rapintegerIgnore items whose RAP is below this.
sortstringdeal = biggest discount, savings = biggest absolute saving, recent = newest; rap and price rank by those.
typestringugc_limited or regular_limited (classic).

No output schema declared.

No examples provided.

get_community_holdings ~165

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.

NameTypeReqDescription
directionstring
kindstringitems = individual Limiteds, creators = whose work is held.
limitinteger
offsetinteger
querystringPart of an item or creator name.
sortstringtotal_copies = most copies held, unique_owners = held by the most different people.

No output schema declared.

No examples provided.

get_creator ~84

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.

NameTypeReqDescription
creator_idstringNumeric creator id.
namestringCreator name. Omit if giving creator_id.

No output schema declared.

No examples provided.

get_item_details ~209

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 breakdown of how it was calculated (every input, its weight and how many points it moved the chance and profit-size blends, then the equation), and a summary of its price trend. Use the breakdown to explain why an item scores what it does. 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.

NameTypeReqDescription
asset_idstringyesNumeric Roblox asset id, e.g. "1365767".
trend_daysinteger

No output schema declared.

No examples provided.

get_market_cap ~154

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.

NameTypeReqDescription
daysintegerLength of the range in days; 9999 for the whole series, which reaches 2021 on two items and 2022-11-24 for the rest.

No output schema declared.

No examples provided.

get_market_stats ~61

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.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

get_new_limiteds ~156

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

NameTypeReqDescription
all_experiences_onlybooleanOnly items sold in any experience — the ones a buyer can list in their own game and keep the 40% affiliate commission on.
availabilitystring
hide_freebooleanDrop items the creator released at 0 R$.
limitinteger
max_age_daysinteger
querystringPart of an item name, to search within recent releases.
resellable_onlybooleanOnly items whose resale window has opened.
sortstring

No output schema declared.

No examples provided.

get_player_holdings ~87

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.

NameTypeReqDescription
limitinteger
roblox_user_idstringyesNumeric Roblox user id, e.g. "27170037".

No output schema declared.

No examples provided.

rank_creators ~213

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.

NameTypeReqDescription
directionstring
limitinteger
offsetintegerRows to skip, for reading past the first page.
querystringPart of a creator name, to rank within matching creators.
sortstringchance = how often their releases end up profitable, score = RBX Invest's creator rating, totalValue = RAP across everything they have made, copies = copies of their items in circulation, uniqueItems…

No output schema declared.

No examples provided.

rank_players ~131

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.

NameTypeReqDescription
limitinteger
metricstringvalue = total RAP held, copies = number of copies held, growth = average lifetime appreciation across holdings (only players holding 3 or more copies are ranked).
offsetintegerRows to skip, for reading past the first page.

No output schema declared.

No examples provided.

search_items ~517

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 1/7/14/30 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.

NameTypeReqDescription
asset_typestringOnly this kind of item, e.g. Hat, HairAccessory, FaceAccessory, BackAccessory, Face, Gear. Omit for every kind.
availabilitystringavailable = copies still in stock from the creator.
directionstring

item_typestringregular_limited is a classic Limited, ugc_limited a UGC one.
