AI agents already use your web app. They're just doing it poorly: screen-scraping, driving Playwright MCP through human-shaped UIs, and working around frontends never built for them.

WebMCP changes the contract. A new rising W3C standard, it brings MCP into the frontend: apps register structured, discoverable tools that agents call, reusing your existing auth, personalization, and business logic. Going agent-ready this way can be much faster than traditional MCP servers.

This talk starts with the basics: registering tools, defining schemas, and making frontend functions agent-callable. We’ll use Claude Desktop to drive a frontend-only document-retrieval app via WebMCP.

Then, we’ll push the frontend even further with a research assistant running fully in-browser, featuring multi-agent coordination, semantic search, multiple WebMCP tools, and on-device models. Navigating some stumbling blocks and hacks, we’ll tour the impressive world of web-based AI and agents

You'll walk away with an introduction to the frontend-for-agents landscape and concrete next steps to prototype against WebMCP and start building today for the AI agents arriving tomorrow.
