The State of Artificial Intelligence APIs

About this report

The largest market this research measures — 5,190 organisations — and the only one that has genuinely adopted the agent layer: MCP runs at 35.8%, the highest recorded anywhere and 2.8 times the median market. It is also the market that skipped every rail that makes an agent surface safe to drive. Idempotency is missing at 88%, consent and delegated identity at 91%, dry-run mode at 99%, and the described-workflow count is zero.

1062 companies. Kin Score median 52.3, Agent Readiness median 43.9. 104 reach the Exemplar band; 3222 sit in Emerging or Minimal. Every one of them is named and ranked in the report — if you work in this market, you are in the table, and so is everyone you compete with.

The AI industry adopted the protocol it invented and none of the safety rails that make it drivable. It shipped the door and skipped the locks.
