This server exposes 8 tools with mixed quality. Naming is generally action-oriented (excel_edit, exec_command, fs_read, fs_write, fs_ops, fs_search, generate_image, kb_search), which is good. However, critical issues emerge in schema completeness, parameter descriptions, and output documentation. Most tools lack explicit parameter type definitions visible in the schemas provided. Descriptions exist but are often generic or translated (Chinese descriptions suggest possible translation artifacts). No explicit error handling patterns are documented. The server bundles multiple operations under single tools (excel_edit combines 7 different edit types; fs_ops combines 5 operations), which reduces clarity for LLM tool selection. Security concerns are present: exec_command allows arbitrary Python execution with minimal visible restrictions, and several tools perform write operations without documented permission gates.

• Document output schemas for all 8 tools. For each tool, specify: response type (object/array/string), required fields, field types, and examples. For fs_read: {path: string, content: string, format: string, lines?: number}. For fs_search: {results: [{path: string, type: string, relevance?: number}], total: number, limit: number}.
• Split bundled tools into single-responsibility tools. Create separate tools: list_directory (list), create_directory (mkdir), move_file (move), delete_file (delete), get_file_info (info) instead of fs_ops. Similarly, split excel_edit into excel_update_cells, excel_apply_formula, excel_format_range, etc.
• Add explicit permission gates to exec_command. Document that it runs under the 'sandbox' user with enforced resource limits (CPU, memory, file I/O quota). Require an explicit 'confirm=true' parameter for irreversible code execution. Log all invocations with timestamp, code, user, and result to stderr or external audit log.
• Add error recovery guidance to all tools. Document error categories: retryable (timeout, temporary network), user-fixable (invalid path, wrong format), fatal (permission denied). Return structured errors: {error: string, code: string, recovery_hint: string, retryable: boolean}.
• Clarify mutually exclusive parameters in generate_image. Update schema: exactly one of chart_data, mermaid_code, html_code is required. If multiple are provided, return error: 'Specify exactly one of: chart_data, mermaid_code, html_code'.
• Add pagination support to fs_search and kb_search. Add parameters: offset (default 0) or cursor (for cursor-based pagination). Return response: {results: [...], total_count: number, limit: number, offset: number, has_more: boolean}.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
