WebMCP Implementation
A practical guide for websites that want to expose genuine user actions to browser agents safely.
Start with one real user goal
Choose search, support lookup, a quote request or another workflow people already complete. A WebMCP tool should describe a useful capability rather than mirror every visual button.
Use document.modelContext
Register a tool with a name, description, inputSchema and execute function. Feature-detect the browser API and preserve the human-facing form as the fallback.
Protect consequential actions
Booking, checkout and submissions need a visible confirmation boundary and server-side authorization.
