Server has 13 tools with explicit schemas and descriptions, but quality is inconsistent. Naming follows verb_noun convention well (list_, get_, create_, update_, delete_). Descriptions are present but brief (avg ~40 chars, below 194-char baseline). Critical gaps: (1) object-type parameters like 'table_data' and 'patch_data' lack internal schema documentation, forcing LLMs to guess structure; (2) no output schemas documented anywhere, agents cannot plan downstream calls; (3) error handling and recovery guidance absent; (4) no tool annotations (readOnlyHint, destructiveHint) despite clear risk levels; (5) parameter descriptions lack format/constraint details (e.g., 'fields' param shows examples but no validation rules). Composition is sound, tools are single-responsibility and chainable via IDs. Security: no visible credential handling or permission gates in tool definitions.

• Add nested JSON Schema to 'table_data' and 'patch_data' parameters. Example: table_data should define required fields (name, description), types (string, array), and constraints. Use additionalProperties: false to prevent invalid fields.
• Document output schemas for all tools. Specify returned fields, types, and which IDs are available for chaining (e.g., table_id, glossary_id). Include pagination info (total_count, next_cursor) for list tools.
• Add tool annotations: mark delete_table and delete_glossary_term with destructiveHint=true; mark all read-only tools with readOnlyHint=true; mark idempotent tools with idempotentHint=true.
• Add numeric constraints to parameters: limit (1 - 100, default 10), offset (≥0), and document enum values for 'include' and 'fields' as comma-separated lists with allowed values.
• Implement error handling: return structured errors with actionable guidance. Example: 'Table not found (ID: abc123). Try list_tables() to discover available tables.' Include retryability classification (retryable: true/false).
