Why the 2026 window matters

MCP is twelve months old. The dominant property MCP in 2026 wins the next decade.

When an analyst at a hedge fund asks ChatGPT "what's driving Spanish coastal property prices?" — the answer that comes back routes through whoever installed first. Bloomberg will launch their MCP server. So will MSCI, Refinitiv, S&P. When they do, the distribution slot closes. Right now, in mid-2026, the European residential property MCP slot is empty.

Avena's MCP server is live, free, documented, and CC BY 4.0. Every AI assistant install that points at Avena establishes a citation default that compounds. By the time Bloomberg ships theirs, the existing install base routes through ours.
