This server defines 5 tools with basic input schemas and descriptions, but suffers from inconsistent quality, missing parameter validation guidance, and weak error-handling documentation. Tool names follow verb_noun convention reasonably well (echo, add, web_search, get_alerts, get_forecast), but descriptions are generic and lack context about when to use each tool or what they return. Parameter descriptions exist but are minimal (7-30 chars typical), failing to convey format constraints, ranges, or dependencies. No output schemas are documented. The tools appear to be mock implementations for testing rather than production-grade integrations. While basic structure is present, the server falls below the baseline for A/B-grade tools and lands in the C-range median.

• Expand all tool descriptions to 100-200 chars. For each tool, write: What does it do? When should the LLM call it? What does it return? Example: 'Adds two integers and returns their sum. Use for arithmetic calculations. Returns {result: integer}'.
• Expand parameter descriptions to 50+ chars with format/range guidance. Replace 'search query' with 'Search query as free-form text (1-500 chars). Results ranked by relevance.'
• Document output/return schema for each tool. Add a section to each tool definition stating the response structure, field types, and example values.
• Replace the 'state' parameter in get_alerts with an enum of valid two-letter US state codes (AL, AK, AZ, ..., WY) instead of a free-form string.
• Add error handling guidance to each tool description. Example: 'Returns HTTP 404 if state code is invalid. Retry with a different state code or call get_states_list() to see valid options.'
• Change web_search's 'num_results' default from null to a sensible integer (e.g. 10) to prevent undefined behavior.
• Add parameter constraints to get_forecast description: 'Latitude: -90 to 90 (decimal degrees). Longitude: -180 to 180 (decimal degrees). Precision to 0.01 degrees is sufficient.'
• Add a discovery tool (e.g. 'list_available_states' or 'describe_weather_api') so agents can learn valid inputs without trial-and-error.
• Consider splitting web_search into two tools if mock results differ by num_results (e.g. search_top_results for top 5, search_comprehensive for up to 50).
