For site devs: set to true when WebMCP tools may perform a high-stakes action: anything that needs explicit user permission in order to execute. If you’re going to make a purchase, send an email, or book travel.

When to use WebMCP vs. MCP? 🤔
Use WebMCP to make your active website "agent-aware" by exposing UI tools directly in the browser.
Use MCP for connecting agents to external data and services beyond the tab.

Wondering what WebMCP is?
❌ It's not an MCP server
❌ It's not the same thing as Playwright MCP
✅ Instead of automating the UI, WebMCP turns your website into callable tools for AI agents.

This was possible with MCP's sampling (and probably with the coming WebMCP) but that's being sunset now
on a far tangent, i keep wanting a web standard for using local models on people’s devices (or routed through to their preferred subscription), with all their attendant personalization and preferences, for making really nice “chat (locally!) with this webpage” that the site itself helps customize
