memgas-mcp exposes 5 memory-management tools with clear verb-noun naming (memory_search, memory_save, memory_forget, memory_ingest, memory_status). All tools have descriptions (10 - 200 chars, within baseline range) and explicit JSON Schema input definitions with required fields. However, parameter descriptions are sparse or missing: 'query', 'content', 'transcript', and 'id' lack detail on format, constraints, or examples. Output schemas are undocumented, LLMs cannot predict response structure. Error handling is minimal: tools throw generic errors ('missing required argument', 'no such memory') without recovery guidance. The server targets a specialized domain (long-term memory for agents) and implements it coherently, but falls short of production-grade parameter documentation and output clarity.

• Add parameter descriptions to all tools. For memory_search: 'query (string, 1 - 500 chars): Natural language search term. Searches across memory content and metadata.' For memory_save: 'content (string, 1 - 8000 chars): Fact or note to record. Will be indexed for future retrieval.' For memory_forget: 'id (string): Memory ID returned by memory_search or memory_save. Archiving is reversible.'
• Document output schemas. E.g., memory_search returns: {items: [{id, content, scope, kind, createdAt, score}], total: number}. memory_status returns: {totalMemories: number, activeBackends: string[]}. This enables LLMs to chain tools and extract fields.
• Enhance error messages with recovery hints. E.g., 'Memory not found: id=xyz. Try memory_search() to find memories by content, or memory_status() to list available IDs.' This guides the agent's next step.
• Standardize response language to English. Replace Chinese responses with English equivalents: 'Remembered (id): content' instead of '已记住'. Ensures consistent LLM parsing across locales.
• Add 'kind' and 'global' parameter descriptions to memory_save. E.g., 'kind (string, optional, default="note"): Memory type (note, fact, event, person). Helps organize retrieval.' 'global (boolean, optional, default=false): If true, memory is shared across all scopes; if false, scoped to current session.'
