largefile

The server primarily performs file I/O, string processing, and AST parsing. It uses `os.path.expanduser` and `os.path.abspath` for path normalization, but does not restrict file access to a specific directory. Therefore, if the AI provides arbitrary absolute file paths, it could potentially read or write to sensitive system files (e.g., `/etc/passwd`) if the server process has the necessary operating system permissions. Atomic file writes (temp file + rename) and automatic backups are implemented for data integrity. Tree-sitter, a native extension, is used for semantic parsing, which carries the inherent risk of vulnerabilities in native code when processing malformed input, though the server includes error handling and timeouts for parsing. No direct `eval()` or `os.system()` calls with unchecked user input were found. The 'is_binary_file' function helps prevent text operations on binary files, but does not mitigate risks associated with executing them.
