Scored across 4 tools
Each tool has a distinctly different purpose: listing allowed roots, listing directory contents, reading a file, and writing a file. The only potentially similar pair is list_allowed_directories and list_directory, but the descriptions clearly separate them.
All tool names follow a consistent verb_noun snake_case pattern: list_*, list_*, read_file, write_file. The naming is predictable and easy to extend.
Four tools is a reasonable, focused count for a minimal filesystem access server. Each tool covers a distinct core operation and none feel redundant.
The set covers listing and file read/write, but lacks essential filesystem operations like creating or deleting directories, deleting or renaming files, and checking file metadata. Common workflows will hit dead ends.
