The MCP "roots" feature has been deprecated by SEP-2577 (roots capability, listRoots request, and roots/list_changed notification). Remove the roots protocol wiring from the server and the roots-based path restriction it fed in Context. normalizePath now only validates that a path is absolute and resolves it via realpath, without an allowed-roots boundary. See: https://github.com/modelcontextprotocol/modelcontextprotocol/blob/main/seps/2577-deprecate-roots-sampling-and-logging.md BREAKING CHANGE: The roots-based path restriction is removed. Tools no longer limit file access to client-provided roots and now accept any absolute path.
