Detecting WebMCP... Vault idle

The vault you cannot open alone

5 locks. Each breaks a different human sense. Only human and agent together can open it. Human alone fails. Agent alone fails.

How WebMCP makes this possible

Each lock registers one document.modelContext.registerTool() tool. The agent discovers it via getTools() or toolchange event, calls it with structured args, and the page mutates shared DOM state. Human and agent see the same vault. Neither can cheat: tools validate inputs and locks judge deterministically.
