The server demonstrates solid definition quality with well-structured tools, clear naming conventions, and comprehensive parameter validation. All 4 tools follow verb-noun patterns (get_*, search_*) and have detailed descriptions. However, there are notable gaps in output schema documentation and error handling guidance. The tools are read-only and low-risk, but lack explicit error recovery patterns and structured output documentation that would elevate this to A-tier (80+).

• Document the return structure for all tools: explicitly specify that results are objects with fields like 'disclosures' (array), 'total_count' (int), 'retrieved_at' (ISO string), and disclosure object schema (code, name, title, category, url, date).
• Add error recovery guidance to descriptions: 'If no results found, try a broader keyword or check date is within last 30 days.' Include enum-like guidance on disclosure categories.
• For get_disclosures_by_date, explicitly document: 'Returns 400 Bad Request if date is outside the available ~30-day window. Use get_latest_disclosures for recent data without specifying a date.'
• Add examples of expected outputs in docstrings (not parameter descriptions): Show a sample disclosure object with all fields, types, and nullable fields clearly marked.
• Document any rate limiting, API timeout behavior, or partial failure modes (e.g., 'If the API is unavailable, this tool returns a timeout error. Consider retrying or using cached results.').
• Consider adding a helper tool or discovery mechanism to list available disclosure categories and their codes, so LLMs can guide users to valid searches.
