A reusable WebMCP accessibility pattern

No site tool plays for you.
The agent helps the game listen.

MCPilot is a working reference for inclusive web games: evidence carries its limits, capabilities register only after player decisions, and every tune stays reversible.

Shared live state

The human sees the same trial, settings, and results the agent acts on.

Approval is code

The apply tool exists only after visible approval, then disappears.

The check-in can veto

A real comparison waits for a visible UI check-in; sample data can never support an outcome claim.
