Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise.

Declared by sources
What the publisher says
Attributed to the source that supplied each field. Treated as claims, not facts.
Read-only market data on Roblox Limiteds as tracked by RBX Invest: the catalog and its rankings, one item in depth with its price history and score, items currently listed below RAP, recent UGC Limited releases, creator track records, the collector leaderboards, the market in aggregate, and a three-step beginner guide. All prices are in Robux. Each skill takes a JSON object: send a message whose part is {"data": {"skill": "<skill id>", "arguments": {...}}} using the argument names documented at https://rbxinvest.com/api#a2a (they are the same as the MCP server's tools). A plain-text message is treated as an item name search. Every task completes inside the SendMessage call and its result comes back as a JSON artifact; nothing here needs a credential and nothing can write.
