Field notes
Maple places a review layer inside an application rather than routing feedback through separate chat or ticket threads. Its examples preserve details such as viewport width, light or dark mode, reviewer identity, and source-file coordinates, then expose the result to an agent over MCP. The page also describes a maple/visual-review status check that remains red while a visual comment is unresolved. The project identifies itself as Apache-2.0 and says it is in beta.
