Description

From the marketplace listing

Connect Nifty to ChatGPT to analyze and organize your reselling business across every marketplace you sell on. ChatGPT can search and filter inventory, pull full item details and photos, check inventory health, manage favorites, private notes, and labels, review order history and expenses, edit items and update marketplace listings, and analyze sales, profit, and sell-through. Nifty unifies inventory and sales for resellers on eBay, Poshmark, Mercari, Depop, Etsy, and Whatnot.

Release notes

Annotation update. Every tool now sets readOnlyHint, destructiveHint, idempotentHint and openWorldHint explicitly to true or false. Justifications (RO/DE/ID/OW): Read tools, RO=true DE=false ID=true OW=false: search_inventory, get_inventory_item, get_inventory_summary, get_labels, get_pending_edits, get_action_status, get_account_settings, get_edit_item_instructions, search_orders, search_expenses, get_analytics_overview, get_profit_and_loss_report, search_categories, get_category_attributes, search_attribute_members. They only read the user's data or the marketplace taxonomy stored in Nifty; nothing is written and no marketplace is contacted. get_item_images RO=true DE=false ID=true OW=true: read-only, but photos hosted by a marketplace are downloaded from the marketplace's servers. load_dynamic_attributes RO=true DE=false ID=true OW=true: read-only, but calls the marketplace's API live with the user's connected account. Write tools: edit_item RO=false DE=true ID=true OW=false: stages edits in Nifty only (nothing goes live until apply); replaces any pending value for the same field and can stage attribute clears; same input gives the same staged state. discard_pending_edits RO=false DE=true ID=true OW=false: permanently discards unapplied staged edits; repeating discards nothing more; Nifty only. apply_item_edits_action RO=false DE=true ID=false OW=true: overwrites the item's live values with the staged edits and republishes its live marketplace listings; a repeat while edits are pending sends another update. add_draft_listing RO=false DE=false ID=true OW=false: adds new draft listings in Nifty only, never changes existing listings; a repeat for the same marketplace is refused. publish_drafts_action RO=false DE=false ID=false OW=true: creates new public listings on marketplaces from existing drafts; never deletes, delists or overwrites a live listing; each call is a new publish attempt that consumes publish credits. add_labels_action RO=false DE=false ID=true OW=false: only adds item-label links; existing links are skipped. remove_labels_action RO=false DE=true ID=true OW=false: removes item-label links; repeating removes nothing more. create_label_action RO=false DE=false ID=false OW=false: creates a new label; touches nothing existing. update_label_action RO=false DE=true ID=true OW=false: overwrites a label's name, color and description. delete_label_action RO=false DE=true ID=true OW=false: deletes a label and removes it from every item. set_favorite_action RO=false DE=true ID=true OW=false: overwrites the items' favorite flag (false removes it). set_private_notes_action RO=false DE=true ID=true OW=false: replaces the items' private notes (empty clears them). All write tools except apply_item_edits_action and publish_drafts_action act only on the user's data in Nifty.
