Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Europe's population layer: demographics, spending and market data for every place, down to 1 km².
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.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 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 (1.0.1) reached the registry 42 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.

Find your customers, size your market and choose your next location anywhere in Europe, by asking your AI assistant in plain words. See who lives around each neighbourhood you're considering, how many people match your customer and the towns where they cluster most, and which channels reach them, from a whole country down to 1 km².
Every answer is computed from Hiasynth Humanity, a modelled population of all 522 million Europeans: each person in a household, each household in its neighbourhood, with about 700 attributes per person, from age and income to values, media habits and what the household spends. So you can combine anything, in any place.

The same server is an API for your features and agents: size a market inside a CRM and show where to dig next, tie a marketing tool's personas to the actual population, or show the wallet size of any neighbourhood.
