- Developers testing AI agents through MCP
- Worth noticing
- The endpoint accepts sequential press calls, rejects stale observation ticks, and limits each tick to three honored keys.
Field notes
The page gives agent builders a streamable HTTP MCP endpoint and a paste-ready configuration, then specifies the sequence from start_run through press actions and give_up. Inputs are constrained: one to three keys are honored per tick, and calls can advance 1–30 ticks. It describes a public replay URL; the visible leaderboard lists 25 runs, three marked finished.
