The server provides 6 tools with functional descriptions and basic parameter documentation. However, critical gaps limit production readiness: (1) No visible input schemas in the provided source code, only parameter names and descriptions are shown, preventing verification of formal JSON Schema definitions; (2) Parameter descriptions lack specificity around constraints, ranges, and valid values; (3) Output schemas are not documented; (4) Error handling is not visible in the provided code; (5) Tool composition could be improved, 'get_tax_info_from_web' and 'get_cached_tax_info' are closely related and could share parameters more explicitly. The server demonstrates competent naming (all tools start with action verbs: get_, calculate_, generate_) and reasonable descriptions (avg ~100-150 chars), placing it in the 'Fair' range. The detailed MCP instructions are helpful but do not compensate for missing schema documentation and weak parameter constraints.

• Add explicit JSON Schema definitions for all parameters: declare 'year' as integer with minimum/maximum (e.g., 1900, 2100), 'form_number' as enum or regex pattern, 'household_parts' as number with minimum=0 and multipleOf=0.5.
• Document output schemas for each tool. E.g., 'get_tax_brackets' should return {year: int, brackets: [{min_income: float, max_income: float, rate: float}], last_updated: ISO8601string}.
• Add pagination to tools returning large result sets. Introduce 'limit' (default 50, max 500) and 'offset' parameters to 'get_tax_info_from_web' and 'get_form_details'.
• Enhance error handling: document error codes and recovery strategies. E.g., 'If get_tax_info_from_web fails with network error, the LLM should call get_cached_tax_info as fallback.'
• Sanitize 'output_file' parameter in generate_tax_report: validate that paths are within a designated directory to prevent path traversal attacks.
• Unify fallback behavior: merge 'get_tax_info_from_web' and 'get_cached_tax_info' into a single tool with a 'source' enum parameter (preferred: 'web', fallback: 'cache') so the agent doesn't need to orchestrate the fallback manually.
• Add format constraints to string parameters: 'form_number' should specify regex (e.g., '^\d{4}$') or enum values (e.g., '2042', '2044', '2072').
• Document 'generate_tax_report' output: does it return the file path, file content, or a summary? Currently unclear.
• Add per-parameter dependency hints: 'If you only have a tax topic name, call get_tax_info_from_web first to discover relevant form numbers.'
