Role in the system
WebMCP explores how a page can expose typed actions to a browser-mediated agent while retaining the active interface, session and origin context.
TECHNOLOGY
WebMCP is an experimental web-platform proposal for exposing page capabilities as structured tools that browser agents can discover and invoke.
EDITORIAL FRAME
A concise view of its scope, position, limitations and supporting sources.
WebMCP explores how a page can expose typed actions to a browser-mediated agent while retaining the active interface, session and origin context.
WebMCP proposes that web pages register typed tools through browser-native interfaces. An agent can discover an action and invoke validated arguments instead of reconstructing the interaction from pixels and simulated clicks.
The proposal targets local browser collaboration with a human present. It complements backend MCP servers and does not aim to replace websites, accessibility semantics or general browser automation.
WebMCP remains an experimental community proposal with open questions around permissions, embedded frames, user confirmation, output validation and streaming. Production designs should not treat its current API shape as stable.
Its central idea fits Electronic Artefacts: preserve a visible interface while exposing a smaller, typed action surface. A future Knowledge Hub could offer read-only graph navigation or relation-draft tools without giving an agent unrestricted DOM control.
