Critical failures across all dimensions. No input schemas visible in source code, only tool names and brief descriptions in mcp.json manifest. No parameter definitions, type information, or output schemas documented. Descriptions are generic (10-50 chars) and lack actionable context. No error handling guidance, no security considerations, no composition hints. Tool definitions appear inferred from manifest rather than explicitly registered with full schemas. This is a configuration file, not a functional MCP server implementation.

• Add complete JSON Schema for each tool's input parameters. Include type, description, enum/pattern constraints, and required fields. Example: store_json should define 'key' (string, required), 'value' (object, required), 'ttl' (integer, optional, 0-86400 seconds).
• Expand tool descriptions to 50-200 characters with WHEN/WHY context. E.g., 'Store JSON data in persistent memory. Use this to save agent state, conversation history, or long-term context across sessions. Returns storage key and timestamp.'
• Document output schemas for all tools. retrieve_json should specify: {key: string, value: object, created_at: ISO8601, updated_at: ISO8601, ttl_remaining: integer}. view_usage should return: {total_keys: integer, total_bytes: integer, quota_bytes: integer, quota_remaining: integer}.
• Add parameter descriptions for all inputs. E.g., store_json 'key' param: 'Unique identifier for stored data (1-256 alphanumeric + underscore). Used to retrieve or delete later.' 'value' param: 'JSON object to store (max 1MB). Must be valid JSON.'
• Implement error handling guidance. E.g., delete_json should return: 'Key not found. Available keys: [list]. Did you mean one of these?' instead of a bare 404.
