This Electron-based desktop app exposes 16 tools via IPC handlers, not a true MCP server. Tools have basic descriptions (avg ~80 chars) and input schemas with types, but lack critical production-quality details: no output schemas documented, no error handling guidance, no parameter validation rules, no enum constraints where applicable (e.g., export-logs format is an enum but not validated in descriptions), and no idempotency/destructiveness hints. Naming is verb-first and clear (get_, search_, tag_, etc.), which is good. However, descriptions are generic and do not explain WHEN to use each tool or what downstream tools expect. No evidence of pagination, rate limiting, or recovery guidance. The server is STDIO-only (Electron IPC), capping protocol readiness at 50.

• Document output schemas for all tools. Specify field names, types, and what each field represents. E.g., get-timeline should return [{id: number, app: string, timestamp: ISO8601, content: string, tag?: string}].
• Add min/max bounds to numeric parameters. E.g., 'hours' should be 1 - 365; 'limit' should be 1 - 200. State these in parameter descriptions.
• Implement pagination with offset/limit or cursor. Return a 'total' count and 'has_more' flag. Cap default limit at 20 - 50 items to prevent context window exhaustion.
• Add error recovery guidance. E.g., 'If tag-activity fails with "entry not found", call search-timeline first to verify the ID exists.'
• Implement confirmation or dry-run for destructive tools (clear-chat-session, update-setting). Return a confirmation_token that must be passed to execute, or offer a preview of what will change.
