Server has 9 tools with basic schemas and descriptions, but significant gaps limit production readiness. All tools have descriptions (10-100 chars, mostly 50-120 chars, within baseline range), and input schemas are present with Zod validation. However, descriptions lack LLM-optimized guidance on WHEN to use each tool vs. similar ones, and parameter descriptions are minimal. No output schemas documented. Error handling is generic (no recovery guidance, no categorization). No tool annotations (readOnlyHint/destructiveHint). Naming is verb-first and clear, but composition issues exist: send_message and read_messages are tightly coupled; create_task and update_task lack idempotency guarantees. No pagination support despite list_agents and check_tasks returning potentially large result sets. Security: AGENT_ID and BROKER_URL injected via env vars (good), but no permission gates, audit logging, or rate limiting visible.

• Add structured output schemas to all tools. E.g., list_agents should return {agents: [{id, name, lastSeen, status}], total, nextCursor}. Document in tool description and return type.
• Implement pagination: add limit (1-100, default 20) and offset/cursor params to list_agents and check_tasks. Return total_count and next_cursor to enable multi-page iteration.
• Enhance error messages with recovery guidance. E.g., 'Key "xyz" not found. Call get_context() with no key to list available keys.' Categorize errors as retryable vs. user-fixable.
• Add tool annotations via MCP SDK: mark read_messages, list_agents, check_tasks, get_context with readOnlyHint=true; mark send_message, create_task, update_task, share_context with destructiveHint=true. Mark idempotent operations with idempotentHint=true.
• Document idempotency guarantees. E.g., 'create_task is idempotent: calling twice with the same assignedTo and description returns the same task ID.' Add request deduplication via idempotency keys if needed.
