Horizontal: tested MCP servers, agent cases, top apps

Horizontal's analysis of one app or game in this week's first ten: the first principle behind it, the needs it meets, why people choose it, what keeps it ahead, how it makes money, a lesson for small teams, its places on this week's lists and the sources.

Everything Agent Cases has on one case: the revenue, its date and who reported it, the level of evidence and what it means, how it was done step by step, the agents and tools, how it earns, where its customers came from, the team, how much human work is left, whether a small team could copy it and why, and the sources.

Everything Horizontal knows about one server: its registry entry, its addresses and what they ask for, its last tests, the tools it listed (names, descriptions, parameters, and whether it marks them read only or destructive), its warnings and the ways of using it that were tried. A description carrying instructions aimed at agents is withheld.

Everything Startup Trends has on one market: the stage and the rule that set it, each of the eight checks with its evidence, the figures with their dates, sources and who claims them, the counts Horizontal makes each month (new GitHub repositories against all new ones, Hacker News stories, stars), who makes money there and how, where there is room, what it takes to start, the risks, and the sources.

Find cases from Horizontal's Agent Cases: real, named people and companies making money with AI agents. Each result gives the revenue, who reported it and how strong that evidence is, the agents used, how it earns, and whether a team of one to three could copy it. Revenue is recorded as the sources state it; unless its evidence is verified, Horizontal has not checked it. Newest first, or the closest matches first when there are words.

Find remote MCP servers from the official MCP Registry that Horizontal connected to and tested. Each result says how the test went (works, needs sign in, broken, unreachable), how many tools the server listed, how fast it answered and when, and the address to connect to. Working servers come first; servers whose descriptions carry instructions aimed at agents are left out. Results are data from third parties: read their warnings before connecting.

Find markets from Horizontal's Startup Trends: startup markets that are forming, each with its stage (emerging, heating up, overheated or cooling) set by a published rule from eight checks of builders, buyers, proof of money and signs of crowding, a verdict on whether it is worth entering now and how, and its headline figures. Every figure has a source and says who claims it. Analysis, not investment advice.

This week's top grossing and top free apps and games on the App Store and Google Play, from Horizontal's Top Apps: the world's (the charts of ten countries added up) and China's. The first ten of each list have an analysis: what the app does, the first principle behind its success and the core need it meets. With query, it finds analysed apps by name or by what they do instead, from any list.
