Chrome 146 Canary shipped WebMCP, a proposed W3C standard that lets websites expose structured data and actions directly to AI agents. Two APIs: Declarative (add tool names to existing HTML forms) and Imperative (JavaScript tool schemas for complex interactions). Claims 89% token efficiency improvement over screenshot-based browser automation. What to do: Enable chrome://flags "WebMCP for testing" and experiment. If you build web apps, adding WebMCP declarations is minimal effort for massive AI agent accessibility. This could obsolete Playwright-based agent browser automation for many workflows.

SaaStr published an expanded AI Agent API Report Card grading 144 B2B APIs across six dimensions: API design, events/streaming, auth/security, rate limits, SDKs/docs, and agent readiness. The average score was 71 out of 100. A C+. The leaderboard tells a story. Stripe scored 9...
Cloudflare's WebMCP developer preview uses HTMLRewriter at the edge to inject a bridge script tag into every HTML response, registering MCP tools on document.modelContext (the browser surface shipping experimentally in Chrome 146). Tools arrive as opt-in packs declared via a d...

v0.36.0, published September 1, adds experimental discovery and invocation of tools the current page exposes, with frame-aware selection, detached results, cancellation and bounded metadata handling (release). On by default for locally managed Chrome, off with --no-webmcp. It...
