WebMCP support now available in mcp-handler
The brief
Vercel's mcp-handler 2.2.0 adds experimental support for WebMCP, a proposed standard that exposes tools to agents inside the browser. Developers explicitly opt tools in and load a script from their MCP endpoint. Calls are forwarded to the MCP server using the signed-in user's identity, allowing authenticated tools without a separate browser-side OAuth flow.
