Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Tells an AI assistant how a watch fits a given wrist, with a to-scale drawing. Free, no sign-in.
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.

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.
fit_watchHow one to three watches fit a wrist of a given size, checked against WORN's catalogue of 46,000 watches (case, thickness, lug width): how far each watch's lugs stop from the edges of the wrist, whether it wears bigger or smaller than its case, and how it sits under a shirt cuff.
suggest_sizesThe case diameters and lug-to-lug spans that fit a wrist of a given circumference, and why lug to lug matters more than the case.
start_try_onFor a person who does not know their wrist size, or wants to see watches on their own wrist. Makes a link, with a QR code for a computer, that opens on their phone: the back camera measures the wrist in a few seconds with no tape or coin, then draws each watch on a photo of their
get_try_on_resultThe wrist size the person measured with their phone through a try-on link (start_try_on), the watch they liked best, and how each watch fits that wrist. Says when they have not sent it yet, or when the link has expired.

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 (2.0.0) reached the registry 12 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.
