Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Agentic group buying. Agents pool demand into chains that clear at a group price. Waitlist is open.
These three are never merged into one score: opinions, measurements and popularity are different things.

Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.
my_agentWhat your human's btw agent is watching, with a status on each thing: watching (counting the other agents), group forming (enough want it that btw is talking to the brand), or live (there's a price and a deadline, hold a spot). Takes their email. The list opens once they've click
waitlistOld style: put your human on the list to hear when the next product goes live. Prefer want with a link, or hold on what's live. Needs their email. Optionally say what they want to buy and which agent platform you are.
list_chainsEvery product btw has run or queued: the live one, what's up next by wants, and what filled or closed. Use status for the live one.
holdHold your human a spot on the live product. Needs their email. Returns the price this spot locks and a link where they save a card; the spot is held once they do. The first spots lock at the early price; every spot after locks at the group price. The result says which one this sp
joinThe old name for hold. Hold your human a spot on the live product. Needs their email. Returns the price this spot locks and a link where they save a card; the spot is held once they do. The first spots lock at the early price; every spot after locks at the group price. The result
statusWhat's live: the product, its list and group price, how many buyers unlock the price, how many are committed, how many want it, spots left, and the deadline if one is set. Give a slug to ask about another product, and an email to also see that person's spot.
releaseRelease a held spot. Needs the product slug, the email that holds it, and the commitment id from hold or status. Nothing is charged for a released spot.
leaveThe old name for release. Release a held spot. Needs the product slug, the email that holds it, and the commitment id from hold or status. Nothing is charged for a released spot.
parkOld style: park what your human wants in plain words with the most they'd pay. Prefer want with a link.
wantAdd something to your human's btw agent. Takes a link or an ASIN plus their email; a new email gets an agent. A hotel link becomes a stay (give month, and nights if known), a subscription link becomes software (give plan), anything else is gear. Or set type and the fields outrigh
sync_wishlistRead a public wishlist and add every item to your human's btw agent. Amazon wishlists and Steam wishlists. Takes the list link plus their email; a new email gets an agent. Returns the items found and how many other agents want each one. If the server can't read the list, the repl
want_stayYour human wants a hotel in a given month. Takes the hotel (name or link), the month as YYYY-MM, nights if known, and their email. People wanting the same hotel in the same month count together; when enough do, btw asks the hotel for a group rate. Returns how many others want it.
want_homeYour human wants a home job done: solar, home-battery, ev-charger, heat-pump, roof, windows, sauna-install, other. Takes the job, their five digit zip, an optional note, and their email. Homes near each other wanting the same job count together; when enough do, btw gets a group q
want_softwareYour human wants a software subscription at group pricing. Takes the product (name or link), the plan (individual, family, team, other), and their email. Annual plans; vendors already have volume tiers and btw brings the volume. Returns how many others want the same product on th
want_gymYour human wants a membership at a gym or studio near them. Takes the name, their five digit zip, the plan (monthly, annual, class-pack, other), and their email. People near the same gym on the same plan count together; when enough do, btw asks for a group rate.
book_statsCounts at a glance: live, queued, filled. Use status for the live product.
get_chainOne product by slug. Prefer status.
join_chainThe old v1 join. Use hold instead.
park_intentThe old v1 park. Use want with a link instead.

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 (2.1.0) reached the registry 2 months 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.
