This MCP server exposes only 2 tools, both of which are destructive (shutdown/stop operations) with minimal, uninformative descriptions. The server is fundamentally designed to control its own lifecycle rather than provide useful agent-composable operations. Tool descriptions lack actionable context for LLM decision-making. No input schemas are visible in the provided source code. The tools violate the single-responsibility principle by providing two nearly identical shutdown mechanisms without clear differentiation. The naming is clear (shutdown, stop) but the descriptions provide almost no guidance on when to use each tool versus the other, or what the side effects are beyond a terse statement.

• Add complete JSON Schema input definitions for both tools. Even if they accept no parameters, define empty input schemas with explicit 'type: object' and 'properties: {}' to signal intentional design.
• Rewrite tool descriptions to disambiguate. Example: 'Gracefully shutdown the server, allowing existing connections to complete cleanly within a 30-second timeout. Use this for planned maintenance. Returns success only after all handlers finish or timeout expires.' For stop: 'Immediately terminate the server without waiting for connections to close. Use only in emergency cases. Returns immediately without confirmation.'
• Implement a confirmation step before executing shutdown/stop. Add a 'dry_run' or 'confirm_action' parameter (default false) requiring explicit confirmation, or return an 'input_required' result that prompts the agent to confirm before proceeding.
• Document output schemas. Specify what each tool returns on success (e.g., {'status': 'shutting_down', 'timestamp': '2025-01-15T10:30:00Z'}) and on failure (error code, reason, suggested recovery action).
• Add permission checks. Require the calling agent/user to have an 'admin' or 'server:shutdown' scope before executing. Return a 403 Forbidden with a clear message if unprivileged.
• Consider consolidating shutdown and stop into a single 'shutdown' tool with a 'graceful' parameter (enum: true|false, default true). This eliminates ambiguity and reduces cognitive load on the LLM.
• Add rate limiting or invocation guards. Prevent accidental double-invocation of shutdown by tracking the last invocation timestamp and returning an error if called more than once within 5 seconds.
