Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (5)

advise_marketplacesread-onlyAnswer "where should I sell this?" for one item. For each US marketplace: whether it accepts the item under its published policies (prohibited and restricted items, condition rules, approval-only categories), the fees and profit at the expected price, the lowest price that meets an optional profit goal, and when the seller gets paid. Every rule cites the official page. Returns picks (highest profit, best margin, fastest payout), ranked marketplaces, ones needing approval, and excluded ones with reasons. Doesn't model demand or the price buyers will pay.
calculate_feesread-onlyCalculate the seller fees, net payout, profit, margin and ROI for selling one item at a given price on one US marketplace, itemized fee by fee from the marketplace's official fee schedule. For Amazon FBA and Walmart WFS, include package dimensions to add fulfillment fees.
compare_marketplacesread-onlyRank every supported US marketplace (or a chosen subset) by the profit the seller keeps when selling one item at the same price. Returns the best marketplace, each marketplace's fees, payout and margin, and any marketplaces skipped or rejected with the reason.
find_target_priceread-onlyFind the lowest list price on each US marketplace that reaches a goal: a profit in USD, a profit margin percent, or an ROI percent. Results are sorted from cheapest required price; marketplaces where the goal can't be reached are listed with the reason.
list_marketplacesread-onlyList the supported US marketplaces with their valid categories, options, whether package dimensions are needed, the official fee pages used as sources and the date each was verified. Call this first to find valid category and option values.

Schemas: list_tools.
