WebMCP lets websites publish structured tools for AI agents
Overview
WebMCP is a standard that lets web developers publish structured tools for AI agents to call, instead of agents interpreting screenshots or page structure, according to an O'Reilly Radar article.
Developers register a tool through document.modelContext with a name, description, input schema, and an execute function that reuses existing application logic.
The browser makes these tools available to a supported agent while the page is active, the article says. The article states that WebMCP is distinct from MCP, the separate protocol it is named after.
