WebMCP Browser Tools
WebMCP is a browser API specification — published as a W3C Community Group Draft by contributors from Google and Microsoft (February 2026) — that enables web applications to expose their own UI functionality as MCP tools to AI agents.
Direction of data flow: Web App → exposes tools → AI Agent calls them.
This is the reverse of web scraping. The web app author decides what functions agents can call. The agent doesn't read the page — it calls structured tools the page registered.
Critical Distinction
| Scenario | Correct Tool |
|---|---|
| Agent fetches content from an external website (BLS, Ongig, news sites) | WebFetch or mcp__Exa__web_search_exa |
| Web app exposes its own actions (add to cart, filter results, submit form) to an AI agent | WebMCP |
| Agent automates a browser (click, fill, navigate) | mcp__chrome-devtools__* or Playwright |
WebMCP is not a web scraper, crawler, or search engine. It is a tool registration protocol for web apps that want to be first-class AI-callable services.
