Server has 7 tools with basic schemas and descriptions, but significant quality gaps. Tool names lack consistent verb-noun structure (check_availability, get_list_dbs vs query). Descriptions are present but generic (avg ~60 chars, below 194-char baseline). Parameter descriptions exist but lack detail on constraints, formats, and dependencies. No output schemas documented. Error handling is minimal. The query tool accepts complex nested objects (where, fields) without clear format guidance. Credentials are passed via environment variables (good), but no per-tool permission gates or audit logging visible. Overall structure is functional but falls short of production-grade tool design.

• Rename 'query' to 'query_table' and 'check_availability' to 'check_csmar_availability' for clarity. Ensure all tools follow verb_noun pattern.
• Document output schema for each tool. E.g., get_list_dbs returns {databases: [{name: string, table_count: integer}]}. Include all fields the LLM might need for chaining.
• Add enum constraints to schema for 'lang' parameter (values: ['0', '1', '2']). Document 'where' parameter format with an example: {field_name: value, operator: 'eq|gt|lt'}.
• Add error handling section to each tool description. E.g., 'login: Returns error if credentials invalid (user-fixable: ask for new credentials) or if CSMAR service unavailable (retryable after 30s).'
• Specify result limits and pagination. E.g., 'query returns max 1000 rows; use offset/limit for pagination. If result_count > limit, include next_offset in response.'
