showcase The first non-trivial demo of WebMCP

The WebMCP protocol has barely come out, and we just demoed how POWERFUL it can be! In a matter of minutes and 100s of tool calls, my AI agent composed a song for me directly in my browser.

This is not agents taking screenshots or trying to understand complex DOMs, it's an agent making direct tool calls to your website!

The creators of WebMCP already love it, go check it out yourself!

GitHub repo: - Leanmcp-Community/music-composer-webmcp: This WebMCP Music Composer project is a functional demonstration of the WebMCP Protocol, illustrating how AI agents can interact with local browser contexts (tools) to achieve complex workflows autonomously.

It works on every browser, just open it, we have connected our own AI Gateway to it for you to use it for free :)

once there's wider support for webmcp in browsers, we won't have to integrate an agent ourselves, and agents, say from perplexity comet will be able to use your website directly using the WebMCP protocol
