This MCP server has severe definition quality issues. Only 2 tools are exposed (read_file, list_directory), both with minimal descriptions (under 100 chars) and incomplete parameter documentation. Schemas are present but lack depth, parameters have type and description, but no constraints (enums, ranges, patterns). No output schemas are documented. Error handling is absent, no guidance on what happens when a file is not found or a path is invalid. The tool names follow verb_noun convention (positive), but descriptions are generic and do not explain WHEN to use each tool or what the LLM should expect. No security considerations are visible (e.g., path traversal validation, permission checks). The server appears to be a proof-of-concept rather than production-grade.

• Expand read_file description to 100-200 chars: 'Read and return the full contents of a file. Supports text files (UTF-8, ASCII). Returns error if file not found, unreadable, or exceeds 10MB. Use this to inspect code, config, or documentation.'
• Expand list_directory description: 'List files and subdirectories in a given path. Returns up to 100 entries per call. Use offset/limit for pagination. Returns error if path does not exist or is not a directory.'
• Add output schema documentation: read_file returns {content: string, size_bytes: number, encoding: string}; list_directory returns {entries: [{name: string, type: 'file'|'dir', size_bytes: number}], total: number, offset: number}.
• Add path validation: document that paths must be absolute or relative to a safe root, and that '..' traversal is blocked. Include example: 'path: "/home/user/project" (must not contain ..).'
• Add error classification: 'Returns error_not_found if path does not exist, error_permission_denied if access is blocked, error_too_large if file exceeds 10MB. Suggest alternatives or retry with different path.'
