The server provides 3 read-only tools for querying news data via NewsAPI. Tools have descriptions and input schemas defined, but exhibit moderate gaps: parameter descriptions are present but generic, output schemas are not documented, and error handling lacks recovery guidance. The decorator-based tool registration via FastMCP is clear, but the code snippet is incomplete (truncated mid-implementation), limiting full assessment of error handling and response structure.

• Add structured return type documentation to each tool. Example for search_everything: 'Returns {articles: [{id, title, source, url, publishedAt, content}], totalResults: int, page: int}'. This enables LLMs to extract IDs and chain calls.
• Enhance parameter descriptions with validation rules and examples. Instead of 'Comma-separated source IDs', write: 'Comma-separated NewsAPI source IDs (e.g., bbc-news,cnn). Max 20 sources per request. Invalid IDs are silently ignored by the API.'
• Add error recovery guidance in tool descriptions or separate error documentation. E.g., 'Returns 401 if API key is invalid (check SERVER_ADDRESS and authentication). Returns 429 if rate limit exceeded, wait 24 hours or contact NewsAPI support.'
• Document result limits and pagination strategy. Update page_size parameter description to: 'Number of results per page (1 - 100, default 20). Use pagination to retrieve more than 100 results. Response includes totalResults; compute max_pages = ceil(totalResults / page_size).'
• Clarify tool selection logic. Add to tool descriptions: 'Use search_everything for keyword search across millions of articles with date and language filters. Use get_top_headlines for current breaking news by country/category. Use get_sources to discover available news sources before querying.'
• Complete the server.py implementation and add error handling code. Validate inputs (enum constraints for language/country codes), catch API errors, and return actionable messages like 'Invalid country code: got "ZZ". Valid codes: ae, ar, at, ... (see docs).'

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