Environment Name Required Notes ROSLYNMCP_SANCTIONED_ROOTS No Server-owned filesystem boundary for path validation and solution discovery. Path-separator-delimited (';' on Windows, ':' on macOS/Linux). '.' scopes the server to its working directory. An empty value fails closed: every path-taking tool rejects its input.
Tools show up when the registry metadata or the repository README lists them. GitHub enrichment fills this in when a token is configured.
