- The hook downloads the artifact and writes it locally, setting executable permissions on non-Windows platforms; no integrity check appears in the inspected installer.
- The launcher spawns the downloaded binary when invoked.
- The download URL uses a GitHub releases path named for rivemcp.
- The download runs from the install hook, while the binary runs when the user invokes the launcher.
