This MCP server exhibits significant quality gaps across definition, schema documentation, and parameter clarity. Of 4 tools, only 2 have minimally acceptable descriptions (weather, health.ping). The csv_rag tools lack proper schema documentation in the source code provided, and parameter descriptions are sparse. Tool naming is reasonable (weather, health.ping, csv_rag.ingest_folder, csv_rag) but some tools use compound names (csv_rag.ingest_folder mixes a namespace with an action). Schemas are partially visible but incomplete, integer parameters like batch_size and top_k lack range constraints, enums, or validation guidance. No evidence of error handling patterns, recovery guidance, or output schema documentation. The server uses fastmcp (HTTP) but tool definitions appear inferred rather than explicitly registered with full schemas in the provided source.

• Add range constraints to integer parameters: batch_size (1-1000, default 32), top_k (1-100, default 10). Include these in the parameter description as 'Batch size for processing (1 - 1000, default 32).'
• Document output schemas for each tool. For weather: return {city: string, temperature: number, condition: string, humidity: number}. For csv_rag: return {results: [{score: number, content: string, source: string}], total_matches: number}.
• Expand tool descriptions to 100-200 characters explaining WHAT, WHEN, and WHAT TO DO WITH IT. Example: 'Query CSV RAG to search ingested CSV content. Use after csv_rag.ingest_folder() succeeds. Returns ranked results with source files and match scores.'
• Add error recovery guidance: 'If weather lookup fails, the city name may be ambiguous, ask the user for a more specific location (city, state, country).' For csv_rag: 'If no results found, try broader search terms or call csv_rag.ingest_folder() to ensure CSVs are indexed.'
• Specify folder_path format: 'Absolute or relative path to a folder containing .csv files. Must be readable by the server process. Symlinks are followed. Returns error if path does not exist or is not a directory.'
• Add idempotency guidance to csv_rag.ingest_folder: 'Calling this tool multiple times on the same folder is safe, existing data will be updated, not duplicated.'
• For weather tool, clarify city format: 'City name, optionally with state/province and country (e.g., "San Francisco", "San Francisco, CA", "San Francisco, CA, USA"). Partial names will attempt fuzzy matching.'
