No agent calls WebMCP yet. Here's the honest case for shipping it today — and how to know the day that changes.

Short summary

WebMCP isn't wired into any mainstream AI agents yet (ChatGPT, Claude, Gemini all still scrape DOM), but shipping low-cost, feature-detected tools today is strategically sound: the cost is minimal (one afternoon, no migration debt), and instrumentation from day one lets you see exactly when agents arrive. Feature-detect navigator.modelContext, reuse existing handlers, log tool calls—so you capture value the moment adoption tips.

• •WebMCP adoption cost is minimal: feature-detected, additive, zero runtime risk
• •Real value emerges when agents start calling tools—instrumenting early lets you see it
• •Ship with proper instrumentation (beacon logging) to avoid the 'set and forget' failure mode
