Overview
- An analysis argues that WebMCP would move agents from parsing pages to invoking site-defined actions such as searchFlights or checkout with explicit parameters.
- It contrasts today’s screenshot- and DOM-driven loops—described as slow, token-heavy, and brittle—with direct function calls that bypass visual inference.
- The piece cites reported evaluations claiming up to 89% token savings and more than 60% less processing compared with screenshot-based methods.
- The approach is framed as a shift from a document web toward an action web where websites advertise capabilities rather than just content.
- The article warns that sites without such capabilities could become less visible to agents, potentially altering how discovery and ranking work.
