A few seconds later the agent hands back a clean, confident shortlist. The names look right, the ranking reasonable. Everyone moves on. https://rinaldofesta.com/thoughts/mcp-isnt-dead.html Tue, 19 May 2026 00:00:00 +0000 https://rinaldofesta.com/thoughts/mcp-isnt-dead.html A recruiter at Cosmico opens a chat and types one sentence: "start the match for deal X."
