Source Code
Section titled “Source Code”Everything Ritual serves over a network offers its source, as section 13 of the AGPL asks: the footer of every site build-site produces (and of a site serve --api hosts), the foot of the admin site’s navigation, and the MCP server’s instructions. Each names the Ritual version and its license, and links to the source of exactly that version: the release tag for a release build, or the commit for a development build.
A modified build should point those links at its own source; see Development for RITUAL_SOURCE_URL.

Ritual downloads Scryfall’s bulk data files into a local card cache rather than looking cards up one at a time, so most commands never touch the network. None of these sites is affiliated with Ritual.
