Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Save and organize web finds in persistent, user-controlled collections for AI assistants.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.

Works in Claude on the web, desktop and mobile:
https://mcp.grabbitapp.com/api/mcpRun this in your terminal
claude mcp add --transport http grabblist https://mcp.grabbitapp.com/api/mcpPaste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{
"mcpServers": {
"grabblist": {
"url": "https://mcp.grabbitapp.com/api/mcp"
}
}
}Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.
Paste into .vscode/mcp.json in your project

ChatGPT connects only to servers on the internet:

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
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", pla
delete_itemSoft-delete one or more items (restorable with restore_item). Example: id=[" ", " "].
restore_itemBring soft-deleted items back. Example: id=" ".
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=" ", 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=[" "].
delete_collectionDelete a collection; its items stay in the Grabblist. Example: id=" ".
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=" ".
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=[" ", " "].
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".

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (2.2.1) reached the registry 2 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
