Raw values for browser-devtools-mcp in namespace io.github
io.github.serkan-ozal/browser-devtools-mcp · Registry status: active
No name of its own reaches this register for this entry. The heading therefore carries the trailing segment of the identifier; the identifier itself is listed below as a coordinate.
What the source declared verbatim, unchanged and uninterpreted. The derived values on the overview page are computed from these.
Evidence for this page: The values on this page come from several collections. Each row therefore states its own origin.
