In my opinion sites that want agent access should expose server-side MCP, server owns the tools, no browser middleman. Already works today.

Sites that don’t want it will keep blocking. WebMCP doesn’t change that.

Your point about selenium is absolutely right. WebMCP is an unnecessary standard. Same developer effort as server-side MCP but routed through the browser, creating a copy that drifts from the actual UI. For the long tail that won’t build any agent interface, the browser should just get smarter at reading what’s already there.
