The MCP 2026-07-28 revision marks the Sampling feature deprecated under SEP-2577, eight months after the revision that expanded it. A field log on what the deprecation registry actually says, why elicitation survived and sampling did not, and what to check before rewriting anything.
Elicitation has been in MCP since June 2025, but the current 2026-07-28 revision changed how it is delivered and calls the old pattern a breaking change. A field log on the three-revision diff, why elicitationId became requestState, and why the statefulness advice inverted.
MCP Apps went stable as the first official MCP extension in January 2026. A pre-build field log on the identifier mismatch, the bilateral opt-in that fails silently, the deny-by-default CSP, and which hosts actually render one in August 2026.
A three-month field log on the best MCP servers in 2026: the five that earned a permanent slot, the ones I uninstalled, and the context and trust costs no listicle mentions.
I wire an MCP server to my IDE's agent in about thirty minutes, and suddenly it reads my real Postgres schema and project files instead of hallucinating. MCP is just a standard way for agents to call external tools. I pick one server that solves a real annoyance, drop a small JSON config with command, args, and env, restart, and let the agent fetch its own context. That's the whole win.
