The Kagura Memory Cloud MCP server has significant definition quality issues. While 9 tools are registered with basic schemas and descriptions, most descriptions are generic and under 100 characters, parameter documentation is sparse, and output schemas are completely absent. Only 3 tools (remember, recall, forget) have moderately complete input parameter documentation. The remaining 6 tools (reference, explore, update, get_context_info, list_contexts, load_guardrails) have minimal or missing parameter descriptions. No tool provides output schema documentation, which is critical for chaining. Tool naming follows verb_noun conventions (remember, recall, forget, etc.), which is good, but descriptions lack the specificity needed for LLM tool selection, they do not indicate when to use one tool vs. another similar one (e.g., recall vs explore both retrieve memory information but serve different purposes). Error handling and recovery guidance are absent from all tool descriptions.

• Add detailed output schema documentation for all tools. For recall and explore, include sample result structures with fields (memory_id, subject, body, relationships, etc.), total counts, and next_cursor/pagination tokens if applicable.
• Expand tool descriptions from 1-2 sentences to 3-4 sentences explaining: (1) what the tool does, (2) when to use it instead of similar tools, (3) what data it returns, (4) any prerequisites or dependencies. Target 80-150 characters per description.
• Add descriptions for all missing parameters. For 'forget', add 'memory_id: The unique identifier of the memory to delete'. For 'reference', clarify whether external_url and memory_id are mutually exclusive or if both can be provided.
• Document return types for list_contexts and recall. Include field names, types (string, object, array), and whether results are paginated. For recall, specify what 'limit' actually caps (number of results? tokens? distance threshold?).
• Add error handling guidance to each tool description. Example: 'If memory_id is not found, returns error code 404. Try recall() first to discover valid memory IDs.'
• Implement pagination for tools returning multiple results (recall with limit, explore, list_contexts). Return a total_count and either next_cursor or page/offset parameters.
• For 'forget', consider adding an optional dry_run or confirmation_required parameter, or document that the tool requires explicit confirmation before execution.
• Clarify parameter constraints. Add minimum/maximum bounds for depth (explore), limit (recall), and other numeric parameters. Document whether context_id and memory_id are opaque system IDs or user-readable names.
