Grabblist is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
pingCheck connectivity and return the server version. Example: call once when a session starts.get_wishlistList saved items as static snapshots (prices as of save time). Example: platform="amazon", limit=20.get_itemFull snapshot of one saved item. Example: id from get_wishlist or search_saved.add_itemSave a page as an item: a static snapshot, nothing is monitored afterwards. Send only values present on the page; price is optional (omit for videos and free content); og:image is fetched when image is omitted. Example: url, title="Sony WH-1000XM5", price=349, currency="NZD", pladelete_itemSoft-delete one or more items (restorable with restore_item). Example: id=["<uuid1>", "<uuid2>"].restore_itemBring soft-deleted items back. Example: id="<uuid>".search_savedKeyword search over saved items. Example: query="standing desk", limit=10.update_priceRecord a new current price on an item (manual correction; the old price is kept for comparison). Example: id, price=299.update_itemEdit fields on one item, or the same fields on up to 20 items (batch: attributes replace instead of merge). Example: id, status="shortlisted", notes="best value so far".list_collectionsWithout id: all collections with item counts and totals. With id: that collection and its items; the other parameters filter and sort those items. Example: id="<uuid>", status="shortlisted", sort="price_asc".create_collectionCreate a collection (folder) for items, optionally with a budget. Example: name="PC build", budget=1500, budget_currency="NZD".add_to_collectionPut an existing item into a collection. Example: collection_id, item_id.remove_from_collectionTake items out of a collection; the items themselves are kept. Example: collection_id, item_ids=["<uuid>"].delete_collectionDelete a collection; its items stay in the Grabblist. Example: id="<uuid>".update_collectionChange the name, icon, color, description, budget or sharing of a collection; omitted fields stay as they are. is_public=true returns the public URL. Example: id, is_public=true.link_itemsLink two items with a relation: alternative, complement, upgrade (to_id replaces from_id), duplicate, same_seller. One pair via from_id/to_id/relation, or up to 20 via pairs. Example: from_id, to_id, relation="alternative".get_item_graphAn item with every linked item and the relation type. Example: id="<uuid>".unlink_itemsRemove one relation between two items. Example: from_id, to_id, relation="duplicate".get_item_historyChange events for an item: who changed what, when and why. Example: item_id, limit=10.get_collection_activityRecent additions, removals and edits in a collection. Example: collection_id.set_pinned_itemsPin up to 3 "Top Picks" shown first on the collection share page. Example: collection_id, item_ids=["<a>", "<b>"].send_feedbackMessage the Grabblist team: bug, parsing failure, feature request or feedback. Only when the user asks or agrees; show them the text first. Example: type="parsing_failure", tool="add_item", url, message="price not found".https://mcp.grabbitapp.com/api/mcpNot in Muse's Connectors list yet, but Muse can still use it.
