WebMCP: the page registers its data as tools for the agent in your browser
Across 30 boards the page now registers 32 different tools with the browser's document.modelContext (Chrome's origin trial, versions 149 to 162 on desktop and to 156 on Android; at most 8 on one page): 29 read-only data tools from the MCP catalog, the same data the page shows at the depth you see it, plus open_board, get_page_context and get_desk_notes. An agent that supports WebMCP reads the board instead of scraping it; a chip in the top bar lists the tools and a short notice appears when one is called. No account key is involved, there is nothing to sign up for, and nothing the agent sends is stored. Details on /developers#webmcp.
