Responded
The server completed its last measured handshake. This is an observation, not a guarantee.

Unmeasured means there is not enough evidence to decide. How these checks work
Start using Grabblist
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.
Claude Code
claude mcp add --transport http grabblist https://mcp.grabbitapp.com/api/mcpCapabilities
Save 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", platform="noelleeming".
DiscoveredPut an existing item into a collection. Example: collection_id, item_id.
DiscoveredCreate a collection (folder) for items, optionally with a budget. Example: name="PC build", budget=1500, budget_currency="NZD".
DiscoveredDelete a collection; its items stay in the Grabblist. Example: id="<uuid>".
DiscoveredSoft-delete one or more items (restorable with restore_item). Example: id=["<uuid1>", "<uuid2>"].
DiscoveredRecent additions, removals and edits in a collection. Example: collection_id.
DiscoveredFull snapshot of one saved item. Example: id from get_wishlist or search_saved.
DiscoveredAn item with every linked item and the relation type. Example: id="<uuid>".
DiscoveredChange events for an item: who changed what, when and why. Example: item_id, limit=10.
DiscoveredList saved items as static snapshots (prices as of save time). Example: platform="amazon", limit=20.
DiscoveredLink 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".
DiscoveredWithout 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".
DiscoveredCheck connectivity and return the server version. Example: call once when a session starts.
DiscoveredTake items out of a collection; the items themselves are kept. Example: collection_id, item_ids=["<uuid>"].
DiscoveredBring soft-deleted items back. Example: id="<uuid>".
DiscoveredKeyword search over saved items. Example: query="standing desk", limit=10.
DiscoveredMessage 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".
DiscoveredPin up to 3 "Top Picks" shown first on the collection share page. Example: collection_id, item_ids=["<a>", "<b>"].
DiscoveredRemove one relation between two items. Example: from_id, to_id, relation="duplicate".
DiscoveredChange 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.
DiscoveredEdit 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".
DiscoveredRecord a new current price on an item (manual correction; the old price is kept for comparison). Example: id, price=299.
