Single tool 'search_datasets' has a clear verb-noun name and basic schema with typed parameters. However, the description is generic (58 chars, below the 194-char baseline), lacks context on when to use it vs. other discovery patterns, and provides no guidance on output structure or pagination. Parameter descriptions are minimal. No error handling guidance, no output schema documentation, and no indication of result limits or pagination support. The server exposes only one tool with limited sophistication, typical of early-stage implementations.

• Expand tool description to 150 - 250 chars: explain that this discovers available Eurostat datasets, when to call it before fetch_dataset, and that results are paginated. Example: 'Search the Eurostat catalogue for datasets matching a keyword (e.g., GDP, unemployment). Returns dataset IDs, titles, and descriptions. Call this first to discover available data before fetching. Results are paginated; use limit and offset for large result sets.'
• Document the output schema explicitly in the description or as a separate schema field. Specify: dataset_id (string), title (string), description (string), last_updated (ISO 8601 date), total_results (integer), has_more (boolean). This enables LLMs to chain to fetch_dataset with the correct field names.
• Add bounds and guidance to 'limit' parameter: 'Maximum number of results to return (1 - 100, default: 20). Eurostat API caps results at 100 per request; use pagination for larger result sets.'
• Add error handling guidance to the description: 'Returns empty results if no datasets match the query. Try broader keywords or check eurostat.ec.europa.eu/catalogue for available datasets. Network timeouts (>60s) are retryable.'
• Migrate from STDIO to HTTP transport (Streamable HTTP or HTTP+SSE) to enable remote accessibility and compatibility with hosted MCP clients. STDIO limits the server to local-only use.
