MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)

These three are never merged into one score: opinions, measurements and popularity are different things.

It passed 3 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 (1.0.2) reached the registry yesterday.
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.

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Briox credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/briox/
On first connect you provide the Country of your Briox account (Sweden or Finland), your Account ID (the long number in parentheses next to your company name) and an Authentication token (Admin → Users → Application Token; Briox registers API developers first). The server validates it and stores it per user. No keys go in config files.
