Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Flight fares seen on thousands of routes, each dated, and where a group can meet. Not live. No key.
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.
cheapest_routesThe cheapest cached fare on every route we hold from an origin (or into a destination), cheapest one-way first, each with its cheapest round trip of a 3 to 21 day stay in `return` when we hold one. Filter by a maximum price and a departure month here rather than by reading the li
find_airportsLook up airports and city codes by name, or list the airports near a code or a lat,lon point. Use it to turn a city name into the IATA code the other tools take.
meet_linkA link to a2bflight.com's group page for people flying from different homes to meet in one place. Use it when the user already knows where; where_to_meet when they ask where. Without dates it picks the weekend whose round trips we have seen price everyone, with each fare and the
route_faresEverything we hold for one airport pair: the cheapest one-way, the cheapest round trip of a 3 to 21 day stay, the cheapest one-way by departure date and by month, and the cheapest round trips. When we hold no fare for the pair, it looks the route up at our fare source; if the far

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 (1.1.0) reached the registry 11 days ago.
